Most apps leave you with a pile of highlights you'll never open again. ZenRead links each quote to related ideas across your whole library, then draws the entire web as an interactive graph you can explore.

The problem with every other reading app
Notes apps bury them in folders. Goodreads forgets them. A highlight that never resurfaces is a dead idea. ZenRead is built the opposite way. Every quote becomes a node you can link to any other, so the longer you read, the more your library connects. The connections are the product.
Built around the connections worth keeping
Capture is effortless and the essentials are all free. The connecting is what makes it yours.
Every book, beautifully
Open a book to a full-bleed cover, your rating and status, the genres, and every quote you've saved from it, all on one calm, distraction-free page.
Quotes page
Capture quotes by typing, scanning an ISBN, or photographing the page with on-device OCR. Each one keeps its page number, your notes, and links to other books.
Quote preview
Open any quote to see your thoughts and the other books it's linked to. The @-mentions and references turn a single passage into a doorway across your library.
Reading, at a glance
Totals for books, quotes and favorites, a breakdown by status, plus your average rating and top genre. A quiet dashboard of everything you've read.
Right on the home screen
The home screen opens to a living snapshot of your reference graph, showing the books and quotes you've woven together, centered on your latest thought, with the hubs gently breathing. One tap steps you into the full, interactive map.
Make it yours
Dress your reading journal in the palette that feels right, and every screen follows along.
ZenRead Pro
A captured quote that never gets revisited is a dead quote. Pro draws the threads between ideas, across authors, books, and years, so what you've read keeps working for you.
See your whole library as a constellation, with books glowing as hubs and quotes orbiting the book they came from. Pan, zoom, and tap to follow a thread, or collapse and filter links to keep even a large library readable.
Link a passage directly to related quotes anywhere in your library. Build your own web of ideas across authors, books, and centuries.
Your library lives on every device and is safely backed up, so a new phone never means starting your reading life over.
Inside the reference graph
Every book and every quote becomes a node; every @-mention and quote-to-quote link becomes a thread between them. The result is a constellation of everything you've read, one you can pan, zoom, and explore.
Explore
Books shine as hubs and your quotes orbit the book they came from, so related ideas gather into clusters you can actually read. The more a book connects across your library, the larger and brighter it glows.
Stay focused
A big library shouldn't become a tangle. Fold every book down to a single hub for the big picture, show only each node's strongest links when things get busy, or spotlight one idea to dim everything but its direct connections.
Simple pricing
The whole reading journal is free. Pro draws the threads between your ideas: link any quote to related passages across your entire library, and watch your reading form a map only you could have made.
Everything you need to keep reading.
No sign-up. Just install and read.
Connect the ideas. Keep them everywhere.
