MetaTana

Official

Docker app from watari_dev's Repository

Overview

MetaTana is an AI-powered media manager for the library you already own. Point it at a folder and it identifies every movie, show, and anime title using AI vision and trusted metadata providers, then enriches everything with artwork, subtitles, trailers, cast, and crew. It renames and organizes files into a clean, consistent structure and writes sidecar metadata your player can read.

It fixes the things that make a library feel broken: wrong matches, missing posters, duplicate copies, inconsistent naming, and half-identified seasons. A health score shows what still needs attention.

MetaTana is metadata-only and downloader-agnostic. It works alongside any media server, including Plex, Jellyfin, Kodi, and Emby.

Setup notes:

  • Map App Data to /app/data so your library, settings, and thumbnails survive a container update.
  • Map your media share under /media. Use Read/Write so MetaTana can organize files, or Read Only to scan without changing anything.
  • PUID 99 and PGID 100 are Unraid's usual nobody:users identity for share access.
  • Sign in with an email code on first run. A free account is enough for local library features.
