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.
