What you are seeing is NotebookLM it is by Google it is meant as a study tool. You can go and upload a couple PDFs and generate a podcast to listen to while you work. I would say like many things automated - if you cannot do it yourself than it can benefit you but if you can read the paper and understand it well the AI talking about it is probably going to be the worse than just reading it yourself. Maybe it could be good again if you wanted to grab a bunch of niche topics and see if something with a big perception could offer any unique insights.

notebooklm.google it can actually be nice if you just want to passively get the gist of something while you are doing something else.
