CullKit: NAS Photo Cull & Rate

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.

AI culling, right on your device

• Every photo gets on-device scores for sharpness, faces, eyes open, and overall quality

• Bursts and near-duplicates are grouped, with the best shot suggested and side-by-side compare

• Auto-cull pre-selects keepers and rejects in one tap; every suggestion is revertible

• Filter and sort by AI verdict, check key faces up close, zoom to full quality

• A cull intensity slider decides how strict the AI is: keep more or keep less

• All analysis runs on your iPhone, iPad, or Mac. No photo ever leaves your device
