AniSync - An anime addon offering tracking, rich metadata, recommendations, and much more!

AniSync synchronizes your anime watchlists with MyAnimeList, AniList, and Simkl in real-time with AI-powered recommendations, discovery catalogs, RPDB & TOP Poster overlays, and filler episode tagging.

Aside from basic tracking, it also adds a few quality-of-life visual features:

• Guest Mode: Browse discovery catalogs and configure the addon without logging into any tracker - perfect for trying out the addon first.
• Multi-Tracker Sync: Automatically mirrors your watch progress across MyAnimeList, AniList, and Simkl in real-time, so you can manage lists on any service and stay in sync everywhere.
• Combined Watchlist: Merges and deduplicates your MAL, AniList, and Simkl lists into a single, clean Stremio catalog.
• Dubbed Anime Catalogs: Discover dubbed anime with a preferred audio language preference (English, Spanish, French, German, Portuguese, Italian) that filters catalog entries by available dub tracks.
• Customizable Catalogs: Configure each catalog independently - pick landscape or portrait orientation, set custom titles, drag-and-drop reorder, shuffle, and preview live before saving.
• 5 Metadata Providers: Choose independently between Kitsu, MyAnimeList, and AniList for posters, backdrops, synopses, and airing data - so the source for each field is yours to decide.
• New Episode, Airing Countdown & Movie Badges: Overlays "New Episode" banners with release countdown and tracker logos (MAL/AniList/Simkl) on TV shows, plus a "Newly Released" badge on anime movies in your watchlist.
• RPDB, TOP Posters & Custom URLs: Show ratings and custom artwork via Rating Poster DB, TOP Posters, or your own URL pattern - whichever you prefer.
• AI-Powered Recommendations: Custom recommendations in Stremio home feed based on your combined MAL + AniList + Simkl watch history, with optional Gemini AI support for enrichment.
• Catalog Sorting & NSFW Filter: Sort by Title, Score, Last Updated, or Airing Date - with title-language awareness (English, Romaji, Japanese) - across multiple sort options, and toggle a one-click NSFW filter to hide adult content.
• Watched & Filler Tags: Prepends clean [Watched] and [Filler] tags directly to episode titles in the player and detail views so you know what you've finished and what you can skip.
