This conversation has been merged. Please reference the main conversation: Lightroom: Automatic image tagging
But one thing I really fell in love with when testing google / apple photos was their auto keywording features. Being able to have all "cars" "landscapes" "animals" etc automatically keyworded makes searching and adding my own keywords exponentially faster.
I found this cool plugin http://wordroom.org/ but it only keywords 1 photo at a time when you manually tell it to.
I know lightroom is in a bit of a different ballgame than google / apple photos but I'm guessing there are a lot more people like me who use Lightroom over those options but would love to see stay competitive in the auto-keywording area as well.
