BOOK MAPS

One book, grown into a tree of ideas.

Upload a book and in a few minutes you get its whole structure: chapters open level by level, all the way down to individual ideas. See the big picture first, then read any section closely — each idea comes with the original text, a plain-language explanation, and a chat to keep asking.

Your first book is free (up to 300K words)

Log in to upload your first book

Your books are visible only to you. Your first book is free within the free allowance.

EPUB · PDF · Word · TXT · Markdown · Up to 100 MB per book

1. Upload a book: EPUB, PDF, Word or TXT. The table of contents is read in seconds, and you see the price before anything starts.
2. Watch the map grow: Each section lights up as it’s organized, so you can start exploring before the whole book is done.
3. Read one section closely: Original text, explanation and a quick self-check sit in the side panel. Stuck? Open a chat about that section.
