A really good example of this is NotebookLM. Feed it anything complex and it will surface a few important points, but it will also spend half the time on the third sentence in the eigth paragraph of section five.

I tried to point it at my Sharpee repo and it wanted to focus on createRoom() as some technical marvel.

I eventually gave up though I was never super serious about using the results anyway.

If you want a summary, do it yourself. If you try to summarize someone else’s work, understand you will miss important points.
