Built for how you actually watch
Local files, streaming, or both. Ryuuji doesn't care — it just keeps up.
Automatic detection
Supports 20+ media players on Linux and Windows, plus streaming services like Crunchyroll, Netflix, and Jellyfin in your browser. All player definitions live in a config file — adding new ones doesn't require touching the code.
Smart recognition
Correctly identifies anime even from messy fansub filenames like [SubGroup] Title - 05v2 (BD 1080p) [ABCD1234].mkv. Fuzzy matching means minor naming differences won't trip it up.
Multi-service sync
Connect MyAnimeList, AniList, or Kitsu and your progress syncs automatically after each episode. Import your existing list from any of them to get started instantly.
Local-first storage
Your library and watch history live in a local database on your machine. Works fully offline — tracking services are optional, not required.
How it works
Three things happen in the background every few seconds while you watch.
Detect
Ryuuji scans for running media players on your system. If you're watching in a browser, it checks the active tab against known streaming services like Crunchyroll, Netflix, or Jellyfin.
Recognize
The anime title and episode number are extracted from the filename or browser tab. Even heavily tagged fansub releases are parsed correctly. The title is then matched against your library using fuzzy search, so small naming differences are handled automatically.
Update & Sync
Your episode progress is updated locally and logged to your watch history. If you've connected a tracking service, the update is pushed there too. Multi-season shows with continuous numbering are remapped automatically.
Works with what you already use
Players, streaming services, tracking sites, and browsers — no switching required.
