I could be behind the curve of course but I hadn't heard before yesterday about a plug-in for LR called Wordroom.
It's a download which acts as a plug-in and uses AI to produce keywords. Select a folder within LR, run the plug-in and Woodroom opens a box showing a copy of the image and offers about 30 key words. Its easy to pick and choose, add your own, delete some - whatever. Click Add to Image and all the key words chosen appear in the LR keyboarding box. Wordroom then goes into the next image and so on.
I loaded it and had a play last night. For topside images it was pretty impressive. Not tried u/w yet. It was fast, suggestions sensible and helpful and beats the heck from flogging through thinking of key words. It adds emotions, movements and colours as well as the obvious features.
The download is free although limits the number of images you can keyword through it a month.
