CullKit: NAS Photo Cull & Rate

Cull RAW from NAS or a folder

Free · In‑App Purchases

Group the photos the AI missed, merge the groups it split, and pull shots back out. Your hand-made groups survive a re-analysis. Cull, rate, and tag thousands of photos fast, straight from your Synology NAS, the Apple Photos library on your iPhone and iPad, an SD card or external SSD, any network share over SMB, or a local folder on your Mac, iPad, or iPhone. Now with on-device AI that scores every frame, groups bursts, and suggests your keepers. Ratings, keywords, and captions sync to Lightroom and Capture One via XMP. No desktop step, no cloud, no lock-in. CullKit turns any photo source into a focused review tool. Point it at Synology Photos, your Apple Photos library on iPhone and iPad, a mounted NAS share, an SD card straight out of the camera, an external SSD, or a folder on your device, then rip through a shoot, mark keepers with stars, and let your ratings and metadata write back to XMP sidecars so Lightroom, Capture One, and Darktable pick them up automatically.

  • This app hasn’t received enough ratings or reviews to display an overview.

The AI groups bursts and near-duplicates for you. Now you can correct it when it gets one wrong. Select two or more photos and group them yourself. Add a loose shot to a group the AI already found, or merge two groups it split apart. The rest of the app treats a hand-made group like any other: the best shot gets suggested, and the stack collapses in the grid the same way. Take photos back out Pull a single photo out of a group, or ungroup a whole stack in one tap. In the compare view you can drop any frame out of the group while you are looking at it. Your groups stay put A hand-made group survives a re-run of the analysis, including a forced one. Start an auto-cull, discard it, and your grouping is exactly as you left it. Tidier toolbar Move, grouping, and Organize by Date now share one Organize menu, so Delete has the corner to itself. Everything still runs on your device. No photo leaves it.
