I'm not even sure what all is going on inside it anymore, because I just add new features when they popup, and tell Claude to do it, and it let's me know when it is done, and every new "input feature" can run against the entire catalogue of files.
Eventually I'll add facial recognition to the photos with one or more people, but I've not felt like delving into that can of worms. I tried it years ago. I've contemplated just training my own model off of the few 10s of thousands of images I have to automatically tag them in a single pass since I have everything labeled already.
