Hrm. Pretty much every LLM summary I've seen of a document I've read, or a meeting I've attended, at absolute best misses important details and overemphasises trivia, and often just flat-out makes stuff up. I'm not sure I want my own _thoughts_ filtered through that.

Have you tried notebooklm at all? I'm actually pretty astonished by it's audio overviews and the insights/summaries it's able to do. Of course, with the right prompt massaging. But it's actually really really well done.
