AirGrabber

AirGrabber is a free, open source Windows desktop app for people who keep their own media library. A calendar shows when the episodes of your series air, including shows on streaming services, and Discover helps you find new ones.

Its built-in renamer, MediaForge, gives episodes and films tidy names from TMDB using your own naming format and moves them to your library folders. It can add posters, trailers and subtitles, and if your setup needs them, quality in the file name, NFO files and background pictures. You see every new name first and can undo any run later.

It can also search torrent indexers and send results to qBittorrent, Transmission or Synology Download Station, and it connects to Plex to show what you have. It updates itself and goes back to the previous version if an update won't start.
