... after a few minutes googling I found a few contenders...

However, nothing is going to be as easy as the google or microsoft ready to go products.

I've been pleasantly surprised by the face- and object-recognition AI in the Synology Moments app: https://www.synology.com/en-us/dsm/feature/moments

Synology is a Network-Attached Storage (NAS) appliance.

I don't think it uploads my data anywhere. If it does, it certainly doesn't upload everything, because I would have noticed the bandwidth usage, but I haven't verified that it doesn't upload some low resolution version of photos.

I'm building that right now. Want to help test it? https://blog.photostructure.com/introducing-photostructure/
