About The Project

Nyaa Enhancer is a browser extension that turns Nyaa into a faster torrent workflow. It adds batch magnet copy, torrent download, and send-to-client actions, an on-page Filters panel, Quick Search, user and keyword monitoring, optional metadata from AnimeTosho, ameNZB, nekoBT, Tsukihime, and SeaDex, and a Similar tab that finds related, recommended, and same-vibe anime. Most options live on a Settings page in the Nyaa navbar; the extension popup is reserved for torrent-client connection details and API keys.

History (/history; enable in Settings → History):

• Each entry stores the torrent info hash from the magnet link (urn:btih:…)

• File size filter with a min/max range slider and unit selectors
• Completed-downloads threshold (greater than, equal to, or less than)

• Related (sequel, prequel, spin-off, movie), Recommended (MyAnimeList + AniList by default, or TMDB if enabled), and Same vibe (shared genres, tags, and studio)
• Adjustable same-vibe mix in Settings; changing it re-scores cached titles without extra API calls
• Click a card for synopsis, score, and links; Ctrl/Cmd-click still searches Nyaa (or opens Quick Search if enabled)
