Genuinely curious, how you manage to derive value from this kind of LLM-assisted reading. At least in the areas I know, the gpt summaries are wrong and generic enough to the point that a read of the book summary, or a read of the preface, is more useful than what the AI returns. If I want to summarize something I provide, it works great. But for these more general overviews I don't trust it.

The handful of business style books I have run through it are wildly accurate and did a great job of summarizing the book chapter by chapter. I would probably not rely on it for technical books but for business books that often have only a handful of key ideas, it works great.
