How the Index works

This page explains how AI Drama Leaderboard verifies and presents series information, and how the Romance Fantasy Index v0.3.6 is calculated.

The Romance Fantasy Index is a reference for comparing dramas whose characters and settings are made with generative AI. Every day, by the same published criteria, it measures the technical quality of each drama’s visuals along with its observed views and audience engagement, and sums them up in one number from 0 to 100. Whether a story is to your taste is yours to decide. The Index exists to help viewers compare many series by the same criteria and find the ones they want to watch.

The site’s pages, series information and the way the Index is calculated may change. Every change is recorded on this page. For now, the Index is based on selected measures of Technical quality and Views & engagement. We keep adding measures and refining the method.

How the Romance Fantasy Index v0.3.6 is calculated

The Index starts from a perfect score. For each Technical quality and Views & engagement measure, points come off in proportion to how far a series falls short of the reference value, and the total deduction is converted to a fixed 0–100 scale and rounded to a whole number. The site operator sets the weights and reference values and manages them as versions of the calculation criteria.
These measures make up the Index. Reference measures add context but do not affect the score. Measures under consideration may be added in a future version of the Index.
- Total: The starting score minus deductions in both categories, converted to a 0–100 scale
  - Technical quality: The technical polish of the AI-generated visuals and editing
    - Picture quality: Image clarity and smoothness of motion
    - Character consistency: Whether each character’s face stays the same throughout an episode
    - Scene transitions: How cleanly one shot cuts to the next
    - Art style consistency Reference only: Whether the visual style stays the same throughout an episode
    - Quality vs. the original Under consideration: Image quality measured against the original video
  - Views & engagement: How often the videos are watched and how viewers respond
    - Average daily views: Average views per day since each original episode was released
    - Engagement rate: Likes and comments as a proportion of views for each original episode
    - Clip & compilation reach: Views and likes on Shorts, highlights and compilations cut from the episodes
    - Story Reference only: How viewers respond to the story is treated as part of views and engagementThe Index does not judge whether a story is good or to your taste, and the story receives no separate score. We assume viewers’ response to the story shows up in views and engagement, and count it there. Each series’ tags describe its genres and themes.
    - View trend Under consideration: Recent growth in views compared with the previous period
Technical quality is the technical polish of the AI production. The originality and variety of the story and its subject matter are not scored separately; we assume they are reflected in views.
Technical quality is measured on a sample of several episodes from each series. Episodes that cannot be measured are left out and the score rests on the remaining samples; the number of samples is shown alongside.
Each measure’s deduction follows the reference values set in the current version of the calculation criteria. Some measures compare a series with the other series scored that day, so an Index can shift even when nothing about the series has changed. Because views are counted differently for Shorts than for regular videos, a series released entirely as Shorts is compared only with other Shorts series. Only the Total appears as a number. The series details show each of the two categories as five segments, and name and describe the two categories and the measures under each.
A series is scored when it meets the inclusion criteria and has at least two episodes free to watch on the tracked platform. How single-video series and Shorts episodes are counted is explained under Inclusion criteria and Episode counts. Views and likes on Shorts, highlights, compilations and other re-edits of the episodes are measured apart from the original episodes, as Clip & compilation reach. Series offered through paid platforms or paid memberships, advertising and promotional videos, video series in webtoon, visual novel or 3D animation form, series whose romance fantasy elements cannot be clearly established from public information, and series whose creators asked to be left out stay on the list as “Not scored.”
We never fill in a value we could not measure. If either scored Technical quality measure (Picture quality, Character consistency) cannot be measured, the series appears as “Pending” with the reason, and without an Index. If every like count is hidden or comments are turned off on every episode, that measure loses all of its points and the Index is still calculated. Wherever you see an Index, every scored Technical quality measure was actually measured. Pending notices say what is being waited for: public episodes, confirmation that a single video holds the complete story, measurements and data, inclusion checks, or a discontinued series.
We keep researching and developing the method so the Index can serve as a reference for comparing series by the same criteria. The version may change without separate notice; every change is recorded in this page’s change history, and Index values from different versions are not compared. To raise an objection or ask a question, contact us as described on the Requests page. The Index moves at most 5 points a day, so a larger change plays out over several days. The cap applies when the series had an Index of the same version the day before; on its first day, or after a day or more without an Index, the Index is that day’s calculated value. This rule applies to calculations from 2026-10-06 onward.

Labels and symbols

▲ / ▼ number: the change from the previous day’s Index. The Index moves at most 5 points a day, so a larger change plays out over several days.
—: no data from the previous day. ═: no change.
AI badge: AI-generated audio or translation, which may contain errors.
Unconfirmed: not yet verified from official sources.
+N: N more languages not shown here.
Ties: series with the same Index are ordered by the release date of their first episode, earliest first. Popularity plays no part.
Not yet scored / Pending / Not scored: the status of a series without an Index. A series receives an Index only after every required measure has actually been measured.
Short-form / Long-form: verified episodes of 10 minutes or less are short-form; longer ones are long-form. If only Ep. 1 was checked, the label says so.
K-AIDrama: appears beside the creator of a series that is likely a Korean production, based on the creator’s and series descriptions or an original title written in Hangul.
Index: the Romance Fantasy Index. The number in the list and the popup is its total (0–100); “As of (date)” is the date it was calculated for.
Five segments: the popup shows each of the two categories as five segments. The more segments are filled, the fewer points that category lost; the segment bounds are fixed within a version.
N-episode sample: a series whose technical quality was measured on two episodes or fewer shows that number under its Index in the list. The popup lists the sampled episodes.
N episodes released: the highest episode number currently available. Released is the day an episode became watchable (Korea time). Free means you can watch the released episodes without paying. “Free · Early access for members” means members see new episodes first, and “Free through Ep. N” means a paid platform’s series is free up to Episode N.
Scheduled: an episode whose release time the platform announced in advance has a dashed outline and a clock icon, with the time shown in your time zone. Once that time passes, it looks like the other episodes and counts toward the episodes released and the latest episode; if a check after that time still finds it unreleased, it reads “Not yet released.” Episodes not announced in advance appear once they are released.
On hiatus: no new episode has been released in 30 days, and the series has not been marked complete.
Last checked: the day each listed source was checked.
Available languages: audio and subtitle languages available from Episode 1 onward, based on Episode 1 and the other episodes we checked. Subtitles found only in specific episodes are labeled “Ep. N only.” The “Available in English” filter uses this language information.
Filter and tag buttons: tap to cycle through Included → Off → Excluded. Included (filled) shows series that match that filter. Off (outlined) leaves that filter inactive. Excluded (crossed out) hides matching series.

How series information is verified

Inclusion criteria

The list centers on romance fantasy. To identify its elements in a series, we look at the relationships, the setting, the synopsis and the videos together. A historical setting, or a focus on growth, revenge or adventure, does not by itself rule a series out of the Index, and a separate fantasy premise is not required either. Series whose romance fantasy elements cannot be clearly established stay on the list without an Index.

A series is listed when it meets requirements 1–4 and neither exclusion 5 nor 6 applies. Items 7–11 cover how listings are maintained and corrected, and what is published.

Being listed means a series meets the inclusion criteria; it says nothing about how good the series is.

1. We identify an AI drama by its video, whose characters and settings are made with generative AI rather than filmed, together with the creator’s description or the platform’s AI label. When neither confirms it, the series is listed only if the operator judges it an AI drama after watching the videos.
2. The episodes of a series are a continuing story released in installments, with a fixed cast and an ongoing plot. A stand-alone video, music video, trailer, recap, clip or re-upload is not an episode, but a music video posted as an episode while a drama is being released counts as one of its episodes. A musical, where the characters’ dialogue drives the story and some of it is sung, is a drama. So is a silent drama, which tells its story and the characters’ lines in on-screen subtitles over background music.
3. A series is listed as soon as its second episode is free to watch on the tracked platform (Shorts included), even if other episodes are paid. A series released as a single video (one without an episode label, or a compilation labeled with a range of episodes) is listed when its title says it holds the whole series (“Full,” “All episodes” and the like), no next episode follows within 7 days of upload, and neither its title, its description nor the creator’s first comment says the story continues. When the operator has confirmed from the series’ own material that a single video is complete, it is listed without the 7-day wait.
4. The Index is calculated once Technical quality has been measured on the sample episodes.
5. If a series reproduces a real person’s appearance or clones a particular person’s voice, with or without consent, scoring is put on hold, without the reason being published, as soon as a report that meets the requirements is received. The hold lasts up to 30 days from receipt, and continues until a formal procedure ends if the reporter shows within that time that one is under way, such as a platform complaint or a rights holder’s formal notice. Scoring resumes when the report is withdrawn or the period ends. Who holds the rights, and whether they were infringed, is settled between the parties through procedures such as platform complaints or lawsuits; receiving a report and holding the score are interim steps while that outcome is pending. The requirements and procedure are on the Requests page.
6. A series reported over the rights to an original work it adapts is handled the same way as in 5.
7. A series with age-restricted episodes is not excluded; it is simply marked “Age-restricted.”
8. Every series is reviewed again each day. A series that no longer meets the requirements shows as “Pending,” and the status of every video (removed, private, restricted) is checked at the same time. A series also shows as “Pending” if any episode from Ep. 1 through its latest cannot be watched in any episode video or public compilation (members-only episodes aside).
9. Inactivity is never a reason for removal. A series shows as ongoing, completed, on hiatus (no new episode in 30 days and not marked complete) or discontinued (its creator has announced that it has stopped). A discontinued series stays listed and shows as “Pending.”
10. Once channel ownership is confirmed, a creator can ask us to re-measure a series, review it again after a correction, or leave it out of the Index. Requests to delete personal data or stop processing it follow the Requests page.
11. What we publish: the total (0–100), the version of the method and an outline of its measures.

Episode counts

Released episodes are counted from the official channel’s own numbering (titles, playlists, chapters), not from the number of uploads. An episode released in parts (EP1-1, EP1-2) counts once, and an unnumbered “finale” video counts as the last episode. Two episodes released as one video (Ep. 3·4) count as two and appear as one button (Ep. 3·4) in the series popup.
Compilations, trailers, clips such as highlights, remasters, translated editions and soundtracks do not count as episodes. An episode whose title carries a subtitle note such as “[ENG SUB]” is not a translated edition. A compilation of the same series helps us verify which episodes are public, and its views and likes are measured as Clip & compilation reach; it is never used as a sample for picture quality. A compilation that names a season or side story belongs to that season or side story, and a video confirmed to be a compilation is treated as one even when its title does not say so.
In a series released as Shorts, every Short with an episode label counts as an episode. If a series began as Shorts and later moved to regular episodes, the Shorts released before the first regular episode count too. Any other Short from a series with regular episodes is treated as a re-edit of those episodes, not as an episode.
“N episodes released” is the latest episode we have verified. When it cannot be verified, the series shows “Episode count unconfirmed.” For series on the tracked platform, the count is updated from the released episodes found in each day’s collection. A series released as a single video shows that video’s length and its date as the latest episode, with no episode count or average interval, since its episode count cannot be known.
Each season and side story counts as its own series, with its own episode count. Even when a season carries on the numbering of the season before, we count from its own Episode 1 and show the creator’s number in parentheses (for example, Ep. 1 (EP.13)).

Length and format

The total length in the list adds up the runtimes of every released episode, including every part of an episode released in parts. Episodes whose length is unknown count at the average of the others, and the total then says “about”; if fewer than 7 in 10 released episodes have a known length, it reads “total length unconfirmed.” On a platform we do not check daily, the total is estimated from the number of released episodes and the runtime of the verified ones, with “about” when episode lengths vary or only Episode 1 was verified. For a series still releasing, “every N days on average” comes from the gaps between its recent episodes.
When every verified episode runs 10 minutes or less, the format is “Short-form”; when every episode runs longer, “Long-form”; when both occur, “Mixed length.” If only Episode 1 has been verified, the label adds “based on Ep. 1.”

Completion status

A series is marked “Completed” when its official channel says so in the latest episode’s title or description, or in the title of a full-series compilation posted afterward. A series with only a pilot is marked “Pilot.” If those videos say the story will continue or more episodes are coming, or a next episode is scheduled, the series is not marked “Completed” until we have checked.
A series whose creator says in a comment or on a thumbnail that it has ended also shows “Completed” once the operator has checked, and a series whose creator announces that it has stopped shows “Discontinued.” The creator’s statement is listed under Sources.
A series without a verified completion notice shows “Ongoing.”
The latest-episode date is the original release date of the newest episode our collector has found (a re-upload keeps the original date). A series with no new episode in 30 days and no completion notice shows “On hiatus.”
Series on platforms our collector does not cover, such as paid AI drama platforms, show neither the date nor the status.

Audio and subtitles

The original audio language is the one the platform recognized in the speech of the sampled episodes; the uploader’s “original” label is not used. When the episodes disagree, the audio stays “Unconfirmed.” A language the operator has verified by listening takes precedence over the platform’s recognition. A series that tells its story with music and subtitles alone shows “No dialogue” once the operator has checked it.
Subtitle languages come from the sampled episodes’ subtitle tracks and on-screen subtitles: tracks the creator uploaded, subtitles burned into the picture, and the platform’s automatic captions of the speech. When the episodes differ, their lists are combined.
Dub tracks are verified in the official player’s settings panel. We never infer a language from the title or the channel’s language.
Auto-dubbed audio and auto-generated subtitles carry an AI badge; the audio or translation may contain errors.
A track missing from the player does not necessarily mean the language is unavailable. Languages we could not verify are marked “Unconfirmed.” The list shows up to two languages, and +N tells you how many more there are.
The list’s original-audio chips (for example, “Original English audio”) select series whose original audio is in that language; automatic (AI) dubs are left out. “Available in English (including AI translation)” adds, to the series available in English, those with a subtitle track the platform can machine-translate into English; we do not check the quality of that translation or whether every series actually offers it.

Access

“Free”: verified as a public original with no members-only episodes found. It does not guarantee that the whole series is free.
“Free · Early access for members”: every released episode is free, and members see new episodes first. The list’s “Free” filter includes it.
“Some episodes require payment · Free through Ep. N”: a series on a paid platform verified as free up to Episode N. The list’s “Some episodes require payment” filter includes it.
“Some episodes require payment”: a series on a paid platform whose free episodes have not been verified.
“Some episodes are members-only”: we verified both members-only and free episodes.
“Members only”: every verified episode is members-only.
“Viewing options unconfirmed”: members-only episodes exist, but we have not yet fully verified which episodes are public.
“Age-restricted”: some episodes carry an age restriction set by the platform; the label appears beside the access label. Those episodes can be watched on the platform after its age check, and they are left out of the Index (episode count, samples, views).

Production country

K-AIDrama marks series we believe were made in Korea, based on what the creator has published: their profile, series descriptions and comments. The country set on a channel is provisional evidence, and no single piece of evidence decides. If this research has not been done yet, a series is presumed Korean when its original title is written in Hangul. We do not verify where a series was produced or the creator’s nationality.

Cover image

The cover image is a thumbnail from an official video, loaded from the address each platform provides and not stored on this site.

At a creator’s request, the series is shown without one. A series with age-restricted episodes uses the thumbnail of a public episode that is not age-restricted, or none if there is no such episode. When the cover would be a Short’s thumbnail but the first button in the viewing information opens a regular video (a compilation, for example), that video’s thumbnail is used instead.

Reference dates and sources

The line “N series · updated n hours ago” shows how many series are listed and how long it has been since our daily update checked episode information and statistics for the series we collect each day. Hover over the time to see it in UTC. Series on paid platforms are checked when we research their information. “n new episodes” counts the episodes released since the previous day’s update and appears only on days with new releases. The “As of” date in a series’ details tells you when its information was current: the calculation date if it has an Index, the episode collection date if it does not, or the research date if it lies outside our regular collection.
Each series’ sources are listed under “Sources” in its details. For series on the tracked platform, the episode buttons in the Watch section link to the released episodes found in daily collection. Sources and availability may change after the reference date.

Languages

The site is available in English, Korean, Chinese, Japanese, Hindi, and Spanish.
Every series keeps its original title. If the creator has published a title in your language, we show that first, with the original title underneath. Each day we check for translations the creator has added to episode titles, including titles in other languages written into those titles. When the episodes offer no title in a language, we use the name of the channel playlist that collects the series’ episodes, but only if the same name also appears in an episode’s title or description. We use only titles the creator has published. If no title exists in your language, we use AI to translate what the original title means and show it underneath, labeled “Title meaning.” This gloss never replaces the original title and is not used as the page title or on share cards. Creator names appear as written. Audio and subtitle languages are named in your language.
We use AI to write each synopsis and choose its tags from the creator’s descriptions and Episode 1. A synopsis sets up the premise and the relationships in one or two sentences, without giving away the ending or offering an opinion. Tags reflect only what Episode 1 or the creator’s descriptions confirm, so a missing tag does not mean that theme is absent. Tags appear in your language. If a synopsis is not available in your language, we show the English one with a note, and automatically translated synopses are labeled “Machine translation.”

Data updates

Series information comes from the operator’s research; for some series it was drafted and reviewed automatically from the creator’s text and Episode 1. The Index is calculated once a day. As of 2026-11-10. Series information and statistics are collected from each platform’s public data, and the Index is this site’s own calculation under the criteria published here. Series information and statistics are fetched afresh every day, and dated collection records are deleted within the period set by the policies of the platform that provides the data.

Change history

Versions

2026-10-08: Romance Fantasy Index v0.1 went public as defined on this page: its definition, inclusion criteria, measured elements and calculation. From this day on, this page is the reference for this version, and later changes are listed here.
2026-10-16: the calculation moved to Romance Fantasy Index v0.2. The Technical quality deductions and the scale of the total were adjusted. The definition, inclusion criteria and measured elements did not change. The history was recalculated from the stored measurements starting 2026-10-08.
2026-10-22: the calculation moved to Romance Fantasy Index v0.3. Technical quality is now adjusted for series whose picture moves so little that defects are less visible. The other deductions and the scale did not change. The history was recalculated from the stored measurements starting 2026-10-14.
2026-10-31: the calculation moved to Romance Fantasy Index v0.3.1. Scores move less when a new episode changes the samples. The deductions and the scale did not change. The history was recalculated from the stored measurements starting 2026-10-20.
2026-11-04: the calculation moved to Romance Fantasy Index v0.3.2. The resolution of a video whose frame is wider than 16:9 is now read the same as that of a 16:9 video of the same quality. The other deductions and the scale did not change. The history was recalculated from the stored measurements starting 2026-10-28.
2026-11-08: the calculation moved to Romance Fantasy Index v0.3.3. Technical quality counts up to a set level, and series above it receive the same points. Differences above that level have not been confirmed by people comparing the pictures side by side. The other deductions and the scale did not change. The history was recalculated from the stored measurements starting 2026-10-31.
2026-11-11: the calculation moved to Romance Fantasy Index v0.3.4. Engagement rate now leaves out the share of comments and replies written by the creator’s own channel. Character consistency counts only faces that turn into a different person in place within a shot; differences that come from a cut or a change of face angle are no longer deducted. The adjustment of Technical quality for series whose picture moves little has been removed. The other deductions and the scale did not change. The history was recalculated from the stored measurements starting 2026-11-01.
2026-11-11: the calculation moved to Romance Fantasy Index v0.3.6. Scene transitions moved from a reference measure into the score: the more often a series has fragments of one or two frames where one shot cuts to the next (residual cuts), the lower the ceiling on its Technical quality. Because these fragments also catch deliberate effects such as flashes, a series that other defects already hold below that ceiling loses nothing more. The other deductions and the scale did not change. The history was recalculated from the stored measurements starting 2026-11-03.

Entire page

2026-10-06: first public version. The request guidance moved to its own page.
2026-10-17: sentences describing the calculation and the screens were updated to match how they work: when the 5-point daily cap applies, views from before a series is listed, the time at the top of the list, information drafted automatically for some series, total length and release gaps, and the scope of synopses and tags. The 2026-10-16 entry was also corrected. The calculation did not change.
2026-10-21: the people who make the series are now called “creators” in every language (the Korean, Japanese and Hindi pages used words meaning “producer”). The methodology, requests and terms pages now share the list page’s footer (document links and contact address, the note that this is an independent information site, and the copyright line).
2026-10-21: the change history is now grouped by topic. Changes to the Requests and Terms pages are listed in each page’s own change history.
2026-10-22: a “Versions” group at the top of this history now shows what each version changed, when, and the date from which its history was recalculated, and each calculation entry names the version it applies to. The version rule no longer distinguishes major and minor versions: the method is researched and developed continuously, its version may change without separate notice, and objections or questions go through the Requests page.
2026-10-22: the definition of the Index was rewritten to state what is measured, against which criteria, how often and on what scale, and the purpose of the Index was added. The first sentence of the version rule now follows that purpose. The calculation did not change.
2026-10-23: the descriptions of the calculation and of the criteria for series information were condensed to an outline of each item, and earlier entries in this history were rewritten at the same level. The three planned picture-quality measures that compare against the original video are shown as one item. The calculation and criteria did not change.
2026-10-24: the English wording on this page and on screen was revised to read more naturally, including some terms (for example, Completeness → Technical quality, Viewing & response → Views & engagement, Pending inclusion → Pending, Outside scope → Not scored). The calculation and criteria did not change.
2026-10-24: the Japanese wording on this page and on screen was revised to read more naturally, including some terms (for example, 完成度 → 映像の完成度, 視聴量・反応 → 再生数・反応, 編入待ち → 保留中, 表記規則 → 表示の見方). The calculation and criteria did not change.
2026-10-24: the Chinese wording on this page and on screen was revised to read more naturally, including some terms (for example, 完成度 → 画面完成度, 观看量·反应 → 播放量·互动, 待收录 → 暂缓计算, 不在计算范围 → 不参与计算). The calculation and criteria did not change.
2026-10-24: the Hindi wording on this page and on screen was revised to read more naturally, including some terms (for example, पूर्णता → तकनीकी गुणवत्ता, दर्शक संख्या·प्रतिक्रिया → व्यू और प्रतिक्रिया, शामिल होने की प्रतीक्षा → गणना रुकी हुई, रचनाकार → क्रिएटर). The calculation and criteria did not change.
2026-10-24: the Spanish wording on this page and on screen was revised to read more naturally, including some terms (for example, Acabado → Calidad técnica, Audiencia y respuesta → Vistas e interacción, Pendiente de inclusión → Pendiente, vídeo → video). The calculation and criteria did not change.
2026-10-31: the scope paragraph in the calculation section was shortened, and the rules for single-video series and Shorts episodes moved to Inclusion criteria and Episode counts. The sentence on single-video series confirmed complete was rewritten in plain words, and the sentence on when the Index history starts was removed from Limitations. The method and the criteria did not change.
2026-11-07: the Korean wording on this page and on screen was revised to read more naturally, including some terms (for example, 완성도 → 영상 완성도, 내러티브 → 이야기, 편입 대기 → 산출 보류, 공개 형태 → 이용 조건, 완결 상태 → 연재 상태). The calculation and criteria did not change.
2026-11-07: the English wording on this page and on screen was revised again to read more naturally, including some labels (for example, regular update → updated, Complete · 1 hr or less · Free → Completed · 1 hr or less · Free, and the tags Family and childcare → Family & parenting, Sweet romance → Devoted love, Scheming husband → Mastermind husband, Salvation arc → Saved by love). The calculation and criteria did not change.
2026-11-07: the Japanese wording on this page and on screen was revised again to read naturally for Japanese readers of all ages, including some terms (for example, 算出前 → 未算出, 算出対象外 → 対象外, 利用条件 → 視聴条件, ご依頼について → リクエスト・お問い合わせ). The calculation and criteria did not change.
2026-11-07: the Chinese wording on this page and on screen was revised again to read more naturally, including some terms (for example, 人物一致性 → 角色一致性, 评价项目 → 测量项目, 语音 → 音频, 可用中文观看 → 支持中文, 已更新N集 → 更新至第N集), and the Chinese text now refers to the Index as Index throughout. The calculation and criteria did not change.
2026-11-07: the Spanish wording on this page and on screen was revised again so that the site’s own terms read naturally to Spanish-speaking readers (for example, Romance fantástico Index → Index de romance fantástico, Elementos → Qué se mide, Coherencia de personajes → Consistencia de personajes, Contraer/Expandir → Ver menos/Ver más). The calculation and criteria did not change.
2026-11-07: the Hindi wording on this page and on screen was revised again in plainer, more natural Hindi, including some terms (for example, मानदंड → शर्तें, संस्करण → वर्ज़न, अपुष्ट → पुष्टि बाक़ी, केवल सदस्यों के लिए → केवल मेंबर्स के लिए, गणना के दायरे से बाहर → गणना में शामिल नहीं). The calculation and criteria did not change.

How the Index is calculated

2026-10-30: pending notices are grouped into five types based on what is awaited. Confirmation of a complete single-video story is distinguished from too few public episodes; detailed technical causes remain in the internal record.
2026-10-06: (v0.1) only the total is published as a number; the two axes and the items under them are shown by name and description. The total moves at most 5 points a day (from later calculations on).
2026-10-10: (v0.1) the webtoon format among the “Not scored” reasons now includes the visual-novel format, for series whose creators label them that way.
2026-10-11: (v0.1) the “Not scored” reasons now include series made mainly as advertising or promotion, for series whose creators label them that way.
2026-10-11: (v0.1) the “Not scored” reasons now include series whose episodes are only for paying channel members, and unofficial derivatives of an existing original are now scored. Exclusion 6 (unauthorized adaptations) applies to them as well.
2026-10-12: (v0.1) a series that began as Shorts and moved to regular episodes now counts its Shorts episodes before its first regular episode. Previously, every Short in a series with regular episodes was treated as a re-edit.
2026-10-17: (v0.2) a series whose information is drafted automatically from the creator’s text and Episode 1 gets its Index once the review is done, and until then it is also left out of the other series’ calculations; before this, series under review were calculated with the rest.
2026-10-18: (v0.2) a series whose videos all hide their like counts or all have comments turned off now gets an Index. The hidden item gets no weight, and its weight is not spread over the other items. Before this, such a series was shown without an Index as “Pending.”
2026-10-21: (v0.2) the webtoon and visual-novel format among the “Not scored” reasons now includes 3D animation, and it also applies to series the operator identifies from their visual style, not only those whose creators label them that way.

2026-10-18: each label and symbol, and a new “Tags” section (every tag by kind, with its meaning), are explained on this page, and the ⓘ beside the list headings and popup headings links to them.
2026-10-18: each tap now moves a chip in the filters and tags panel through Included → Off → Excluded, then starts over (previously Included → Excluded → Off). The labels and symbols section describes the three states and their order.
2026-10-21: the labels and symbols section gained entries on hiatus and the daily cap, and the note for a score on hold now reads “Scoring is on hold during a review.”
2026-10-23: series with the same Index are listed with the earliest first episode first. Previously, they followed catalog order.
2026-10-23: episodes whose release time the platform announced appear as scheduled buttons (dashed outline and clock), and Released now means the day an episode became watchable: for a premiere, the day it started rather than the day its page went up.
2026-10-25: once a scheduled episode’s time has passed and it looks like the other episodes, the list and the series popup also count it in the episodes released, the total length, the latest episode and “New episodes · Last 3 days.” Before, it was counted only at the next check, so the popup’s episode buttons and the list’s count could differ.

Inclusion criteria

2026-10-30: the notices for paid platforms, memberships and advertising or promotion are combined. Channels introducing paid-platform series are classified with those platforms. Genre-related notices now refer to romance fantasy elements that cannot be clearly established from public information; setting or the emphasis on growth, revenge or adventure alone does not determine exclusion.
2026-10-17: the inclusion criteria now open with the scope of the list: Romance Fantasy at its core, plus series from other eras and worlds, among others, when romance is at the heart of the story.
2026-10-17: a series whose AI-production evidence can no longer be confirmed in the daily check is shown as “Pending” under criterion 8; before this, its Index was still calculated.
2026-10-19: the scope was narrowed back to Romance Fantasy: series in which romance is at the heart of a story set in an imagined world or a reality transformed by fantasy. Series with a contemporary setting that were listed before this change are under separate review.
2026-10-20: at a creator’s request, a series is left out of the Index, and the series and its official video links stay on the list as “Not scored.” A request to delete personal information or stop processing it, or a report of rights infringement, also takes the series off the list.
2026-10-21: a series released as a single video (a video without an episode label, or a compilation labeled with a range of episodes, such as a whole season in one video) is scored without the two-episode requirement if that video runs 20 minutes or longer, and its episode count is not estimated; it shows “Episode count unconfirmed.”
2026-10-21: inclusion criteria 5 and 6 were reworded around the report procedure; what can be reported and how it is handled did not change.
2026-10-21: removal from the list was taken out of the requests in inclusion criterion 10, which now says that requests to delete personal data or stop processing it follow the Requests page.
2026-10-22: a series with any episode, from Ep. 1 to its latest released one, that cannot be watched in any episode video or public compilation is shown as “Pending” (criterion 8, members-only episodes aside).
2026-10-25: series set in the present day or near future without fantasy elements are now listed when romance is at the heart of the story, shown as “Not scored.” Series with a contemporary setting listed before 2026-10-19 follow the same rule.
2026-10-26: a series released as a single video is scored, in place of the 20-minute rule, once its title says it holds the whole series, no next episode has followed within 7 days of its upload and nothing says the story continues. Until then it is “Pending” and its first watch button reads “Watch the compilation”.
2026-10-27: music video series, made of songs and images alone, are no longer treated as dramas and left the list. A music video posted as an episode of a drama being released counts as an episode, and a musical, where the characters’ speech drives the story and some of it is sung, is a drama. A silent drama, which tells its story and the characters’ lines in on-screen subtitles over background music, is also a drama.
2026-10-27: fantasy series that include romance and focus on a female protagonist’s own story, such as growth, revenge or adventure, are now listed and shown as “Not scored.”
2026-10-28: a series whose AI production neither the creator’s description nor the platform’s label confirms is now listed when the operator judges it an AI drama after viewing its videos. Before, only series with such a description or label were listed.
2026-10-29: a series whose creator announced that it has stopped (discontinued) stays listed and is shown as “Pending.” Before, discontinued series were scored.
2026-10-29: series set in a real historical period without fantasy elements are now listed like present-day and near-future series when romance is at the heart of the story, shown as “Not scored.”

Episode counts

2026-10-12: each season and each side story now counts as a separate series. A series that contained several seasons continues as its Season 1, and later seasons and side stories are registered as new series. The “Season 1 complete” label was therefore removed.
2026-10-12: compilations are now stated to count toward Clip & compilation reach and never to be used as video-quality samples. A compilation that names a season or side story belongs to that season or side story. A video confirmed to be a compilation is treated as that series’ compilation even if its title does not say so.
2026-10-19: a season numbered on from the previous one counts from its own Ep. 1, with the creator’s numbering in parentheses (for example, Ep. 1 (EP.13)). For a season whose titles carry no season mark, the series popup notes that the season split is inferred from the channel and its season videos.
2026-10-21: two episodes released as one video (e.g., Ep. 3·4) count as two and appear as one button in the series popup.
2026-10-23: more kinds of separators between an episode label and its number, and of range marks between two numbers, are now recognized.
2026-10-23: more kinds of part marks right after an episode label are now recognized, so an episode released in parts counts as one episode.
2026-10-25: a series released as a single video no longer shows “Episode count unconfirmed”; it shows only the video’s length, since its count is unknowable rather than pending.
2026-10-26: an episode titled only with the name the creator gives the series in another language, or one that says it includes a song (“OST included”), now counts as an episode of that series.
2026-10-26: a series released as a single video now shows, like the others, the latest episode’s date (that video’s) beside its length; the episode count and the average interval stay out.
2026-10-28: the total length now adds up the runtimes of all released episodes, every part of an episode released in parts included, and reads “total length unconfirmed” when fewer than 7 in 10 episodes have a known length. Before, it was estimated as the number of released episodes times the middle of the verified episodes’ length range.

Completion status

2026-10-06: a long hiatus is defined as 30 days.
2026-10-12: the first-episode date is now Episode 1’s own date.
2026-10-26: besides the latest episode’s title, its description and the title of a full-series compilation posted after it are checked for a completion notice (for example “Ep. 6 Final,” “final episode,” or a “(Complete)” compilation). If those videos say the story continues or more is coming, or a next episode is scheduled, the series does not show “Completed” until this is checked.
2026-10-26: a series whose creator says in a comment or a thumbnail that it has ended also shows “Completed” once the operator has checked it. A series whose creator announces that it has stopped shows “Discontinued,” and the Status row has a “Discontinued” chip.

Audio and subtitles

2026-10-12: the uploader’s “original” label no longer sets the original audio language; the platform’s recognition does. When the recognitions disagree, the audio stays unconfirmed, and a language the operator verified is shown instead.
2026-10-17: available subtitle languages are now decided from Episode 1 together with the other checked episodes; other languages are listed as “Ep. N only,” “Available in English” follows the same rule, and the on-screen terms are defined under Labels and symbols.
2026-10-18: when a series’ title is written in Hangul, kana, Devanagari or Chinese characters, subtitles in that language count as available once the checked episodes show them clearly enough, even without Episode 1.
2026-10-18: Korean subtitles of a presumed Korean production (K-AIDrama) follow the same rule as a title’s language.
2026-10-18: on-screen subtitles are also judged in episodes where few frames show text.
2026-10-18: the Language row gained “Available in English (incl. AI translation),” selectable instead of “Available in English,” which also includes series with a subtitle track the platform can machine-translate into English. The audio chips now cover original audio only, leaving out automatic (AI) dubs, and read like “Original English audio.”
2026-10-19: the subtitle lists of each series’ sample episodes are now read, and an episode that contradicts them is rechecked periodically.
2026-10-28: the audio of a series that tells its story with music and subtitles, without dialogue, is shown as “No dialogue” once the operator has checked it. Before, it showed as “Unconfirmed.”

Access

2026-10-18: access now reads “Free,” “Free through Ep. N” for a paid platform’s series, and “Free · Early access for members” when members see new episodes first.
2026-10-18: a series free through Episode N reads “Partly paid · Free through Ep. N” and counts as Partly paid; “Partially paid · Membership” now reads “Partly members-only.”
2026-10-21: episodes the collector cannot see are now told apart as members-only or as private or deleted, so a series with members-only episodes shows that in its access status.

Production country

2026-10-20: a series whose production country was not researched is presumed K-AIDrama when its original title is written in Hangul, the same rule used for a title’s language among the available languages.
2026-10-25: the creator’s own comments are also read as evidence of a Korean production; the country set on a channel is provisional evidence, and no single piece of evidence decides.

Cover image

2026-10-20: a cover whose video is gone is replaced by the thumbnail of the series’ starting video.
2026-10-21: a series with age-restricted episodes now shows a cover image: the thumbnail of a public episode that is not age-restricted.
2026-10-26: a series whose cover would be a Short’s thumbnail and whose first button in the viewing information opens a regular video now uses that video’s thumbnail instead of the Short’s vertical frame.

Reference dates and sources

2026-10-11: the list header and each series popup show one date, “As of …”; its meaning is explained under “Reference dates and sources” above.
2026-10-12: the popup’s source list now adds the released episodes found by the daily collection after the researched sources, which stay as they are.
2026-10-18: episode links now appear only in the episode buttons, and Sources & details lists the other sources.
2026-10-24: the update time at the top of the list (“Updated 2026-10-23 21:24 UTC”) now reads like “179 series · regular check 13h ago · 17 new episodes”: the number of series, the time since the regular check, and the episodes made public since the previous day’s run. The UTC time appears on hover.

Data updates

2026-10-20: the notes on the materials used for measurement now describe their purpose.

Screen layout

2026-10-06: covers sit in a smaller 16:9 frame, a divider comes before the series without an Index, and the Index badge in the header links to this page. Audio and platform marks are monochrome symbols.
2026-10-11: the count of episodes watchable now is no longer shown.
2026-10-17: the series popup now gathers the viewing information (Watch Ep. 1, release and access tags, episodes released and total length, dates, audio and subtitles). The window reads in this order: series (synopsis, tags by kind), viewing, Index and sources; the small numbers after a fact point to the source list below.
2026-10-18: chips that state a fact have square corners and chips you can tap are rounded, and the share cards show the current Index version.
2026-10-18: the list’s “Available in English” switch became chips in the filters and tags panel. Access “Free” and language “Available in English” start on, English and Korean audio chips were added, Completed moved to the panel’s Status row, and “Completed · Under 1 hr” gained the free condition as “Completed · Under 1 hr · Free.” The selected filters are part of the list’s address.
2026-10-18: the filters and tags panel lists the tag rows first, then Access, Language and Status. Access has a chip for each access status a series has, the language chip reads “Available in English” (the language chosen for the site), and Status has Ongoing, Completed, On hiatus and Pilot. A series has one access status and one status, so choosing a chip in those rows replaces the row’s current choice. The note on tapping chips at the end of the panel became a legend at its top (Included → Excluded → Off).
2026-10-18: the list opens with “Free” and “Available in English (incl. AI translation)” on. “Clear filters” removes every filter, including the BL exclusion, and shows every Romance Fantasy series.
2026-10-18: the K-AIDrama chip now works like the BL chip: each tap cycles through included, excluded and off, and the choice is part of the list’s address.
2026-10-18: the list has a field to search titles and creators and a back-to-top button. On narrow screens, the filter line ends with a link to the labels and symbols; each row name in the filters and tags panel has an ⓘ linking to its explanation, and the note on “Available in English (incl. AI translation)” appears under the Language row. On touch screens, the ⓘ, the source numbers and the AI badge are easier to tap.
2026-10-18: the Watch section of a series popup has a button for each released episode (“Ep. 2,” “Ep. 3” …), with “+N” opening the rest of a long series. Status and Access appear as labeled rows like the series tags, the format (Short-form or Long-form) shows in the list only, and the Copy link button sits before the title.
2026-10-18: the legend at the top of the filters and tags panel and the note on “Available in English (incl. AI translation)” under the Language row were removed, and a rule now separates the panel’s rows. The chip is explained in the “Audio and subtitles” section, which the Language row’s ⓘ links to.
2026-10-19: the list opens with “Free” and “Available in English (incl. AI translation)” off. Excluding BL is the only filter at first, shown beside the filters and tags button as “−BL,” like any excluded chip.
2026-10-20: when the creator uploads a compilation of the whole series, the series popup puts a “Watch the full series” button first in the viewing information, and Episode 1 shows as a button like the other episodes. It must be a public video uploaded after the latest episode, whose title names the whole series or that runs from Episode 1 to the latest; a Shorts compilation is used only for a series released as Shorts. Compilations are not used as video-quality samples in the Index.
2026-10-20: the first button in the viewing information and the list’s title and cover links now open a public video the collector has checked. When Episode 1 is gone, they open a compilation from Episode 1 (for example, “Watch Ep. 1–7”) or the lowest public episode, and the episodes before it are marked as currently unavailable. The series page link is kept only for addresses that are not videos.
2026-10-21: episodes that were released and can no longer be watched are no longer noted in the episode summary; the series popup shows their buttons in gray with diagonal lines, without a link.
2026-10-21: age-restricted episodes are also linked from the series popup's episode buttons (the platform handles the age check).
2026-10-21: the first button in the viewing information is “Watch the full series” when the title names the whole series (the series then shows as completed), or “Watch Ep. X–Y” for a compilation of a range.
2026-10-21: the synopsis now opens with an “Our summary” label, and the bottom of the list and the series popup note that this is an independent information site that organizes public information about each series using the same criteria, with a link to the Requests page.
2026-10-21: a green banner at the top of the screen now says that the site cheers on AI creators around the world, and that watch links go to the creators’ official videos while the Index is based on each series’ public information to help viewers discover series; it can be closed. The footers of the list and the document pages are now light green bands.
2026-10-21: a compilation labeled with a range of episodes appears in the series popup’s viewing information as a “Watch Ep. X–Y” button just before the button for its first episode. Of compilations covering the same range, the latest public one is shown.
2026-10-21: hovering over the “On hiatus” chip, the ▲▼ number and the watch links now shows the definition of a hiatus, the 5-point daily cap, and where the video opens (in a new tab).
2026-10-22: a season whose titles mark it also shows “Episodes are numbered from this season’s Ep. 1; the creator’s numbering is in parentheses.” under its episode buttons when they carry the creator’s numbering. The first watch button keeps its text on hover, in white on a darker green.
2026-10-22: the gray hatched buttons in the series popup now start from Ep. 1: an episode before the latest public one that the collector never found is also shown as unavailable (previously only episodes it had seen removed or made private).
2026-10-23: the episode buttons in the series popup’s viewing information always start from Ep. 1 or a compilation that includes it. When Ep. 1 is gone and a series starts at a later public episode, the first watch button takes that episode’s place in the order, and the “+N” fold always shows it.
2026-10-23: the first button in the viewing information and the list’s title and cover links open the first video a viewer can watch, in the order of the episode buttons. Among buttons that start at the same episode, the one covering more comes first: the full series, then a compilation from Ep. 1, then Ep. 1; a series whose earlier episodes are gone starts at the compilation of the next ones (e.g., Watch Ep. 13–22). An episode released in parts opens at its first part.
2026-10-24: tapping a row’s summary and tags also opens the series popup. On a phone, "Details ›" on the Index line is now a bordered button.
2026-10-24: when the creator has published a series title in the interface language, the list and the series popup show that title first and the original title below it, marked "Original title". Search finds the series by that title too.
2026-10-24: a series with no title published in the interface language shows a "Title meaning", translated by this site with AI, below its original title, and search finds the series by it. The share card of a series address also uses the title the creator published in the interface language.
2026-10-25: the label “Our synopsis” became “Synopsis” with the AI mark, and the AI mark of “Title meaning” now follows the label. This site writes the synopsis and chooses the tags with AI.
2026-10-25: the AI marks of the synopsis and the "Title meaning" no longer open a note; the ⓘ beside them links to "Nature of the information and liability" in the terms of use.
2026-10-25: the “Are you a creator?” link to the Requests page now also follows the as-of date at the top of the series popup and the first sentence of the green banner at the top of the screen. The links at the bottom of the list and of the series popup remain.
2026-10-25: for a series not yet completed, a compilation of all its episodes reads “Watch the compilation” instead of “Watch the full series,” and “Watch Ep. 1–N” when the operator has checked which episodes it holds. The pending reason now says it counts episodes free without an age restriction (age-restricted episodes have buttons in the popup but are not used for the Index).
2026-10-26: more ways of writing a range in a title are read (for example, “14-26EP”, or “9~11” in a compilation’s title). A video whose range does not start at Ep. 1 shows as a compilation of that range rather than “Watch the full series,” even when its title says the series is complete.
2026-10-26: a compilation button names its range of episodes or the full series only when the title or description and the measurement agree: the video’s length is within 15% of the episodes it holds, or it says it includes a trailer, side story or remaster. Otherwise, or when it cannot be measured, it reads “Watch the compilation” until the operator checks it.
2026-10-26: the creator’s first comment on a compilation now counts among the creator’s words checked against the measurement. Hovering over a button that reads only “Watch the compilation” shows “The episodes included are still being confirmed.” In the creator’s words checked for a compilation’s range and a series’ completion, a line with a link counts only when the link goes to an earlier or later episode of the same series; a line pointing elsewhere (for example, “Next episode on ○○ 👉”) does not.
2026-10-26: a GL chip is added. The list now opens with GL excluded as well as BL, shown beside the filters and tags button as “−GL,” like any excluded chip. The GL chip appears in the Genre & format row once a GL series is listed.
2026-10-27: when the episodes give no title in the interface language, the name of the channel playlist that collects the series’ episodes is shown as that language’s title, but only if the same name also appears in an episode’s title or description.
2026-11-01: the list has a go-to-bottom button. It appears at the bottom right while more than a screen lies below, under the back-to-top button when both show.
2026-11-07: the Index box in the popup shows each of the two categories as five segments, and a series whose technical quality was measured on two episodes or fewer shows that number under its Index in the list. Labels and symbols explains both.

Limitations

Views & engagement is calculated from recent collections. Views, likes and comments are running totals since release, so they include activity from before the series was listed.
Collection runs once a day, and the statistics are the values at that moment. Changes within a day show up in the next collection, and values for past days are never filled in later.
Technical quality is assessed on a sample of each drama’s episodes.
