So I was trying out another PDF reader just for the hell of it, and was confused about highlighting (There was a tool in the ribbon bar that I was too stupid to use).
Instead of looking through documentation, I actually tried to use the built-in AI to see what wisdom it could offer a peasant like me.
On the same subject, are there any open source PDF readers you can recommend?
Not really a helpful comment but Acrobat Pro is an AI shitshow these days. Either hangs or crashes on launch while it attempts to give me an AI summary of the content which I didnt ask for. I use Firefox to view now instead, opens instantly without all the bloat nonsense.
