Lumidex Studio can find the faces in your library so you can name the people in them and browse everything they appear in — a fast way to pull together every shot of one person across years of photos. Detection runs entirely on your Mac.
Run to scan your catalogue for faces. Like the other library tools it works in the background, is resumable (it picks up where it left off if interrupted), and reads a cached thumbnail rather than hitting your originals on a network drive. It uses Apple's on-device Vision framework — no photo or face data ever leaves your Mac.
Once faces are detected, you assign names to them yourself:
Once you've named someone, selecting that person shows every photo they appear in — across every folder and collection. It's the quickest way to gather, say, every photo of one family member for an album or a gift.
Automatic grouping — where the app suggests "these 40 faces look like the same person, name them once" — isn't available yet. For now, naming is done by hand. Automatic face recognition creates sensitive biometric data, so when it does arrive it will be opt-in, kept only on your Mac, and fully deletable; we'd rather ship it right than ship it early.
Face detection is on-device and off by default — it only runs when you start it. Nothing about the faces in your photos is uploaded, and there's no cloud service involved at any point.
