Cull AI Studio

What Cull AI Studio is
Cull AI Studio is desktop software for photographers who want help sorting photo shoots. Available for macOS and Windows, it analyzes sharpness, exposure, faces, eyes, bursts, and duplicates on the photographer’s computer. Images judged with confidence are sorted into KEEP or REJECT; less certain decisions go to REVIEW for the photographer to assess. Corrections are used to train a personal model locally, with training starting after about a thousand decisions have been recorded.
The app supports RAW files from major camera brands, including Nikon, Canon CR3, Sony, Fujifilm, Olympus, Panasonic, Pentax, and DNG, as well as JPEG, TIFF, and PNG. RAW+JPEG pairs stay together. For Lightroom workflows, it writes XMP sidecars that mark keepers with five stars and green labels, rejects with one star and red, and review images with yellow. Culling works offline, though the subscription needs verification once a week. The 7-day full-feature trial requires no payment card; access pauses at its end unless a card is added and a subscription is started. Monthly service costs $19.99 a month, or the annual plan costs $159 a year; both cover unlimited shoots and photos, one signed-in computer at a time, and updates.
