Read. Listen. Learn. Grow.
The reading app that remembers everything you’ve read — so no great idea ever slips away.
How much of the last book you finished do you still remember?
For most readers, most of it is gone within weeks. MindBook changes that: upload any book or document and it becomes summaries, flashcards, quizzes, and audio you can listen to anywhere — with an AI Book Coach that connects ideas across your whole library and turns what you read into what you actually use.

From a file on your phone to knowledge in your head
Three steps, and the book starts working for you.
1
Upload anything
Add books and documents in PDF, EPUB, MOBI, DOCX, or TXT — a novel, a textbook, a handbook, a work manual. Your library is private and always yours.
2
Read it — or listen
A clean reader with adjustable fonts, themes, and a dyslexia-friendly option. Or press play and listen with natural voices at your speed, hands-free.
3
Learn it, for real
Summaries, explanations in plain language, flashcards, quizzes, and mind maps — plus a Book Coach that remembers it all and connects it to everything else you’ve read.
Don’t just finish books. Keep what they teach you.
Every book you own is full of ideas you meant to use. MindBook pulls them out, connects them, and brings them back to you — built for students, professionals, and lifelong learners who read a lot.
A reader that fits your eyes
Adjustable fonts and sizes, light, dark, sepia, and focus themes, and a dyslexia-friendly typeface. Highlight in your own colors, bookmark pages, and keep typed or voice notes tied to the exact passage.
Listen anywhere
Every book becomes audio. Choose a voice, set your speed from 0.5× to 2×, and keep listening in the background — in the car, on a walk, while you cook.
Study tools in one tap
Summarize a chapter, pull the key ideas, generate flashcards and quizzes, and turn dense passages into plain language. Difficult concept? Tap it and ask AI to explain it simply.
Search everything you’ve learned
One search across every book, note, highlight, and bookmark in your library. That quote from three books ago? You’ll find it in seconds.
Read in any language
Books in any language, with built-in AI translation — read the world’s knowledge without waiting for someone to translate it for you.
Watch yourself grow
Daily reading goals, streaks, a reading journal, and a personal growth dashboard that shows the themes running through your library — and how far you’ve come.
Your next book could stay with you for life.
Start free with up to 10 books, summaries, listening, and your own Book Coach — no card needed, nothing charged today.

Not a chatbot bolted onto a reader — a personal mentor that learns alongside you, book after book. It’s the feature readers ask about most.
- Remembers every book you’ve read and connects ideas across them automatically.
- Builds reading plans around your goals — business, health, relationships, finance, spirituality, study, or personal growth.
- Asks the questions that deepen understanding and helps you turn lessons into real-life action plans.
- Recommends what to read next — including books that challenge your thinking — and brings back lessons before you forget them.
AI Book CoachYour reading mentor
I keep starting books about focus but never finish them. What am I missing?
Looking across the three focus books in your library, they all land on the same point: your environment beats your willpower. You highlighted it twice and then moved on. Want a 7-day plan that turns that one idea into a daily routine?
Yes — and remind me what the second book said about mornings.
It argued your first hour sets the terms for the whole day. I’ve added it as day one of your plan, with the passage you highlighted in March.
An example of how the Coach connects your own library.
Start free. Feel the difference. Then decide.
Your first 10 books are free — no card, no risk. Plus gives you room to grow, and Pro makes it unlimited. Prices in USD.

Questions, answered
What can I upload?
Books and documents in PDF, EPUB, MOBI, DOCX, and TXT — in any language. If you can read it, MindBook can work with it: novels, textbooks, professional handbooks, study materials, and personal documents.
Are my books and notes private?
Yes. Your uploaded books, notes, and highlights belong to you. Your library is tied to your account, and you always own your books, notes, and personal data.
How does paying work?
At launch you’ll create a free account with your email or Google, pick a plan, and check out securely by card through Stripe. Your plan activates on your account as soon as your subscription starts — that’s what raises your book limit and opens up your plan’s AI allowance — unlimited on Pro and Family.
