Bazarr

Bazarr is a companion app for Sonarr and Radarr. It manages and downloads subtitles based on your preferences. You set your preferences for each TV show or movie, and Bazarr takes care of the rest for you.

Please note that Bazarr does not scan your hard drive to detect TV shows and movies: It only handles TV shows and movies that are indexed in Sonarr and Radarr.

Manual search
Find all matching subtitles, select the ones you want, and download them to your media directory under the correct name so that your media player can recognize them correctly.

Subtitle Updates
Regularly search for matching subtitles and update those you have previously downloaded if a better version becomes available.
