With the recent announcement of unlimited photos, I decided to reactivate my auto upload to Google photos (previously, it was eating into my drive space, which I did not like at all)
But yes, you can explore the photos you have uploaded here:
https://photos.google.com/search
The search feature is pretty darn awesome (it is Google after all)
I tried a few random searches to determine the intelligence of the engine
‘Cat’:
This yielded a picture of my friend and a cat and myself and a pomeranian
‘Chick’: (Very impressive, it is able to understand ‘chick’ = ‘girls’)
So yes, my female friends are tagged here (together with her toes and my obviously guy friend and myself)
‘Handsome’:
Well, need to go for plastic surgery I guess.
But yes, have fun and try out the searches inside your own album
