Read deeply.
Become unbound.
Books deserve better software.
Read the world's greatest books in a distraction-free workspace built for deep thinkers. Highlight meaningful ideas, capture lasting notes, and explore every page with an AI companion that helps you understand, question, and connect timeless ideas.
From Bound Books to Unbound Minds.
Crafted for the way serious readers actually think.
Every feature was designed around one question: what does it feel like to truly live inside a book?
A reading experience built for the long session
Multiple themes, typography controls, full dark mode, and progress tracking — tuned for the reader who spends hours, not minutes, with a book.
A companion that has read every word
Ask questions, get summaries, unpack arguments. The AI only draws from what's actually on the page — no generic answers.
Highlights that remember their origin
Mark a passage and it stays permanently linked to the page it came from. Annotate inline, organize by theme.
Your reading memory, intact
Bookmarks, streaks, reading analytics, and the exact paragraph you left off at — across every device, always.
Five centuries of great books. Free, forever.
Philosophy, history, psychology, science, and literature — 500+ public domain titles, always free, no credit card.
The page adapts to you, not the other way around
Fonts, themes, margins, line height — every reading parameter in your hands. Distraction-free mode strips everything away.
Your library. Your progress. Your mind.
Progress, streaks, highlights, and your library — all in one view, across every device you own.
The quiet place where ideas stay.
Themes
Light, sepia, dark, and true black — choose what's easy on your eyes for hours of reading.
Typography
Adjust size, typeface, line height, and margins as you read. Your preferences, always remembered.
Progress
See exactly where you are — by page, by chapter, by percentage. Know how far the story goes.
Highlighting
Mark a passage in a single tap. It stays saved alongside the page it came from, forever.
A companion that has read every word.
It only knows what's actually on the page — no guessing, no generic summaries. Pure, grounded intelligence drawn from the author's own words.
