When you ask ChatGPT to summarize a book, it reconstructs from reviews, blurbs, and training data fragments. It hasn't read the book. iChatbook's summaries are generated from actual indexed chapters via RAG — at 4 depth levels you control.
“Can you make that book for me? Make it 20 pages.”
The question is: what is that “book” actually made of?
Result: Plausible-sounding content that invents experiments, flattens arguments, and omits qualifications the author actually made.
Result: Accurate, chapter-by-chapter understanding that maps to what the author actually wrote.
ChatGPT gives you one shot. iChatbook gives you a dial.
Core thesis and key takeaways per chapter. The “20 pages” Bartlett asked for — except grounded in reality.
Arguments, evidence, and frameworks. Enough to discuss the book intelligently without reading cover-to-cover.
Full argument reconstruction with supporting evidence. You'll know more than most people who “read” the book.
Chapter-by-chapter study notes with concept extraction — the kind of notes a grad student takes over a semester.
Ask ChatGPT: “Summarize Chapter 4 of Thinking, Fast and Slow”
ChatGPT: Produces a confident 500-word summary. Mentions anchoring. Gets the broad concept right. But invents a “salary negotiation study” that doesn't exist in the chapter, omits Kahneman's specific wheel-of-fortune experiment, and misattributes a finding to Tversky that Kahneman credits to a different colleague.
iChatbook: Produces a summary citing the actual experiments from Chapter 4 — the wheel-of-fortune anchoring study, the real estate pricing study, the charitable donation framing experiment — because it processed the real text and can point you to the passages.
