CullAi uses AI to assist you in automatically discarding obvious rejects and to reduce your manual steps and time to pick better photos.Auto Rate helps you in discarding obvious rejects. Auto Pick automatically picks better photos. But even if you want to manually choose, Auto Group, Faces display, Important People and Faster Previews helps you in picking better photos quickly.

Other apps like Photomechanic only have Faster Previews to help you in culling, but you still have to go through each photo manually multiple times before getting final picks.
