Every ChatGPT conversation about a book is an island. Three months later, that brilliant synthesis is buried in chat history. iChatbook builds a persistent library, Idea Graph, and cross-book connections that compound with every book you read.
“Because it has this huge memory on me, it knows what I'm dealing with. It knows the businesses I'm building, the problems I have.”
But does it remember what you learned from the last 20 books? Does it connect Chapter 3 of one book to Chapter 7 of another? No. It remembers a few sentences about you. Not your intellectual journey.
ChatGPT has conversations. iChatbook has a knowledge map that grows with every book.
See how “second-order thinking” appears in Thinking in Bets, The Great Mental Models, and Antifragile — automatically mapped.
Browse 22,000+ auto-extracted concepts from your library. Find unexpected connections.
AI creates learning paths between concepts — “Take me from probability theory to decision-making.”
