Every night it looks at every file in your Plex library through Sonarr, Radarr and Bazarr, finds what will not play right, fixes what is safe to fix, and tells you about the rest in plain words. Nothing is ever deleted; anything it moves can be put back with one click.
The nightly loop
The arrs say what the library should be, the files say what it is, and a finding is the gap between the two. Auditarr never scans your whole disk from scratch: it probes only what is new or changed, so a 10,000-file library takes about 25 minutes the first night and minutes after that.
What a finding is
One file (or one missing episode), one problem, one sentence that says what is wrong and what fixes it. The coloured word says how bad:
won't playwrongwaitingFYI
Won't playNo audio or no video, a zero-byte or corrupt file, a sample instead of the episode.
WrongFrench audio on an English show, a Blu-ray tag on a 720p file, an episode that is really a different episode.
WaitingNo subtitles yet while Bazarr searches, a missing episode the indexers have not found, a duplicate copy.
FYI10-bit, AV1 or Dolby Vision that one of your players cannot play directly; an extended cut; a harmless title mismatch.
Every button is reversible
Nothing is deleted outright. Moves go to a trash folder on the same disk with a countdown, repairs are lossless remuxes that keep the original in the trash, and re-downloads are watched: if nothing better arrives, the original is put back automatically.
What it does on its own
Out of the box every switch that removes a file is Off. You turn things On one at a time, watch Only report for a few nights if you like, and the plan is always visible before the night runs it.
Where it runs
One containerDocker on Unraid or compose. Needs the arr addresses and keys (Setup page), and the media folder mounted at the same path the arrs use.
Its own databaseSQLite in the config folder: findings, actions, history, settings. Backed up nightly; a weekly drill boots the backup to prove it restores.
Tested like it mattersSynthetic media with known defects, a fake arr stack, a browser bot clicking the real buttons, chaos and slow-service drills, all in CI.
