MetaTana sits between your files and Jellyfin. It reviews and writes clean NFO metadata, artwork, subtitles, and sidecars beside your media, then tells Jellyfin to rescan. It does not replace Jellyfin and it does not modify your media files. Jellyfin reads NFO and local images natively, so it is a natural fit.
Jellyfin is only as good as the data on disk. When matches, artwork, and NFOs are messy, your library shows it. MetaTana cleans the source of truth before the scan.
MetaTana writes reviewable NFO metadata and artwork beside your files and triggers a Jellyfin library scan so the corrected data lands in your library. Everything stays as open files you control.
Run MetaTana in Docker next to your server or on the desktop. It reads the local truth already beside your files, proposes reviewable writes, and rolls back cleanly if you change your mind. Jellyfin keeps doing what it does best.
No. MetaTana is not affiliated with Jellyfin and does not replace it. Jellyfin stays your player and library server. MetaTana is the metadata QC layer that cleans filenames, NFO metadata, artwork, and sidecars beside your files, then triggers a Jellyfin scan.
No. MetaTana does not modify your media. It reads filenames and sidecar metadata, writes NFOs, artwork, and sidecars alongside them, and tells Jellyfin to re-scan. Every write is journaled so you can roll back.
Yes. Jellyfin reads NFO metadata and local images natively. MetaTana writes clean NFOs and artwork beside your files and can trigger a Jellyfin library scan, so the corrected data shows up in your library.
No. The media organizer is free, including local BYOK provider lookups. Pro adds hosted AI Vision for difficult matches and MCP automation, but the core Jellyfin metadata cleanup works on Free.
