Duplifind

Duplifind is a duplicate video finder built for people who actually have to clean up a video library — creators, families with years of phone backups, editors juggling exports and re-encodes. Drop in a folder and Duplifind finds exact duplicates by content hash, near-duplicates by matching duration, resolution, and file size, and — with Pro — visually similar re-encodes using on-device comparison. No cloud, no accounts, nothing leaves your Mac.

Review results in a side-by-side comparison view with thumbnails and full metadata (size, duration, resolution, codec, date), then decide with the keyboard: number keys pick which copy to keep, arrow keys move to the next group. Nothing is ever deleted for good — every removal goes to the Trash with a full undo trail.

Keep a library of past scans, export a CSV or JSON report of what was found, and tune matching sensitivity and file types in Settings. Duplifind is a one-time unlock, not a subscription — clean your library once or twice a year and move on.
