I ran one of my papers into it, mind blown how well they dumbed it down without losing too much details (still quite a lot was ommitted). I wonder if it's domain specific, and I wonder what's the variance by topic.
A lawyer friend of mine also suggested giving it the Spanish civil code, a long, arid legal text. The podcast of course didn't cover the whole text in 10 minutes, which would be impossible, but they selected some interesting tidbits and actually had me hooked until the end and made me learn a few things about it, which is no small merit. And my friend was quite impressed and didn't complain about correctness.
Lately, when I just want to get the gist of a long article or research paper, I run it through NotebookLM and listen to the podcast while I’m exercising.
My only complaint is that the chatty podcasty gab gets tiring after a while. I wish it were possible to dial that down.
