Why this tool exists

  • Turns scary duplicate clusters into a reviewable keep/remove recommendation.
  • Explains why a candidate wins so the output feels trustworthy.
  • Bridges cleanly into DupeZappa's preview, move, and delete flows.

Local scope

No upload. No hidden apply step.

Pick a folder and let the browser worker inspect the files you expose. The results stay local and the delete or move decision stays inside DupeZappa.

Keeper recommendation

Run the scan and choose the keep rule.

Keep rule

Your browser is using directory upload fallback. The scan is still local, but empty folders cannot be detected.
