How AniGems compares anime ratings

Compare ratings from MyAnimeList, Bangumi, Filmarks and Gamer, see how the Global Score is calculated, and find an anime to watch next.

What the scores can tell you

AniGems puts ratings from MyAnimeList, Bangumi, Filmarks and Gamer on one page. You can compare each site’s original score, check its rating count and follow the series’ score history.

Each platform has its own users and scoring habits. A difference between sites does not tell us why people rated a show differently, or what an entire country thinks of it.

Use the Global Score to browse the catalog, then check the individual scores and the show’s premise before deciding what to watch.

The four rating sources

Source scores keep their original scales on anime pages. Only the combined Global Score uses a shared 10-point scale.

The AniGems Global Score

Eligible platform scores are converted to a 10-point scale, then weighted by the logarithm of their rating counts. Some titles have fewer than four eligible sources.

How the Global Score is calculated

A source contributes only when its score is within the platform’s scale and it has more than one rating. Missing or ineligible scores are left out.

1. Convert the scaleFilmarks and Gamer: score × 2
2. Weight by rating countScorei × log10(Ratingsi)
3. Calculate the averageSum of weighted scores / Sum of weights

Logarithmic weights reduce the influence of differences in rating counts. They do not adjust for how generously each site scores titles. The result is rounded to two decimals; one person may rate on several sites.

Questions about the data

Why do scores differ between sites?

Scores come from different groups of users, using different scales and rating habits. Converting 3.5/5 to 7/10 aligns the arithmetic, but does not make the two sites’ scores mean exactly the same thing.

Are scores updated as each episode airs?

The website shows the data available when it was built. Update times appear on anime pages. Score history records the whole series at episode milestones, rather than individual episode ratings.

Why is a title or platform score missing?

The catalog does not cover every anime. A title may also lack a match or a published score on one of the four sites. Use the original source links to check what is available.
