CullAi is an AI assistant for professional photographers to select final photos from a photoshoot. It uses AI to auto rate photos based on face capture quality, groups similar photos and auto picks the best ones from those groups.

CullAi calculates AI score of photos by checking for better lit, sharp faces with open eyes. Furthermore, it also detects important people in a shoot and displays faces alongside each photo to quickly check quality manually. Auto Rate, Grouping, Auto Pick, Filters and Fast Previews features help quickly discard obvious bad quality photos.

Photo Groups Grid

This shows all filtered photo groups in a grid with count of photos in each group shown on top right red badge. While CullAi is analyzing photos you will see 1 cell for each imported photo. Once analyzing and grouping is completed you will see group of photos in each cell. Each cell shows most rated picked photo from the group as thumbnail of that cell. In case no photo was rated in a group it just shows thumbnail of the first photo in that group.

You can scroll vertically to see all groups. You can select photo groups using usual selection methods in macOS, Export and Share actions consider selected photo groups or all in case of no selection. Furthermore, you can also drag these photo groups to other apps.
