Every AI headshot product works roughly the same way under the hood, and once you know the shape of it, most of the weird results stop being weird.

You upload 10 to 20 selfies. Twenty minutes later you get 100 portraits back. Some look exactly like you. Some look like your cousin. One looks like you wearing a jacket you've never owned, in an office you've never been to, and that one is usually the most interesting failure.

Here's what's happening in between.

The pipeline has four stages

Face detection and crop. Your uploads get run through a face detector, cropped square, aligned so the eyes sit on roughly the same horizontal line, and resized. Anything where the detector fails, or finds two faces, gets dropped.
