I stumbled upon it as part of my Business Standard account with Google Workspace. I uploaded all content - blog posts... docs of LI posts... and whatever I could find that I'd created. Then --- wow. It's a research tool --- so it's not a creator. but - I'm exploiring what's possible for myself. (I'm a micro-business, teeny tiny) This is a powerful way to use my ideas to source themes for content... then take that to other AI to help me wrote posts, etc... I'm curious if anyone else has used NotebookLM (I expect there are other ways to do what I'm doing - so far this is easy, and uncomplicated.)
