A universal library of books, pre-indexed and ready to interrogate — with AI summaries, cross-book chat, and an authoring workspace that turns the talks, memos, and decks you've already made into a published book. No uploads. No setup.
The Retention Problem
Book summary apps condense books into bullet points. You read them, nod along, and forget everything by next week. That's because reading is passive — your brain doesn't encode information you don't actively engage with.
iChatbook pairs AI book summaries at 4 depth levels with active recall testing, graded quizzes, and spaced repetition — then lets you chat across the entire library and write your own book back into it. Whether you're a professional, student, or lifelong learner — iChatbook is where books live.
Every book interaction in one place — from the first page to your own published work.
A universal library of titles, pre-indexed and ready to query. AI summaries at 4 depth levels — Brief (2 min), Standard, Detailed, and Chapter-by-Chapter Analysis. No uploads needed.
Active recall quizzes, fill-in-the-blank tests, and spaced repetition. The science behind med-school flashcards, applied to every book in the library.
Ask a question. Get answers from multiple authors at once. Cross-book synthesis surfaces agreements and contradictions across the entire library.
Turn your voice memos, decks, and essays into a published book. Three-voice drafts, library-as-sources with inline citations, and publish-and-sell built in.
No uploads needed. Explore AI-powered summaries and study tools for any title in our library.
Instant intelligence for today's most influential books
Join thousands of professionals and students mastering books with iChatbook.
Research Scientist
I previewed 15 books on systems thinking in one evening. Found the two that were actually rigorous — then read them cover to cover. iChatbook saved me from wasting months on the wrong ones.
High School Teacher
My students chat with books before reading them and come to class with real questions. They're reading more than ever because they actually know why each book matters to them.
University Professor
I use the Idea Graph to show students how concepts connect across their entire reading list. It turns isolated books into a coherent intellectual journey.
Business Analyst
I explored five strategy books through conversation, found the one that spoke to my exact challenge, then read it deeply. That single book changed how I approach market analysis.
Content Creator
I used to feel guilty about not finishing books. Now I preview widely, commit to the ones that resonate, and actually retain what I read. I've finished more books this year than the last three combined.
Software Engineer
The knowledge mastery challenges helped me actually retain concepts from technical books. I'm not just reading — I'm building real understanding that sticks.

Homeschool Parent
My kids create their own stories and then get excited to read the real books that inspired them. It's turned reading from a chore into an adventure they ask for.
Medical Researcher
Being able to ask questions across my entire medical library and trace ideas back to their sources has transformed how I do literature reviews. I read more primary sources now, not fewer.
Language Learning Coach
My students preview books at their level, build confidence through conversation, and then tackle the full text. The adaptive approach meets them where they are.
Product Manager
I chat with a book to understand its core argument, then decide if it deserves my weekend. Most don't — but the ones that do get my full, undivided attention.
PhD Student
The persistent memory connects insights across my entire reading history. When I'm deep in a new book, it surfaces relevant ideas from things I read months ago. It makes every book richer.
Corporate Trainer
I build reading paths for my team — they preview, discuss, then commit to the books that fit their growth areas. Engagement with actual reading is up 3x since we started.
