Track what you've read, what you're reading, and what's next
One library for past reads, current reads, and future reads, with a quick search when you want to find a book again.
Reading isn't the hard part. Remembering what mattered is.
Margin is for the sentence you underlined on page 134 and the question it put in your head. It keeps your thinking next to the text, so the reading has somewhere to go after you close the book.
What Margin does
Your library, your thinking, your people.
Read with friends. Create or join a digital book club.
Start a group, invite your friends, and keep every discussion threaded under the book it is about.
Revisit ideas without digging or re-reading everything
Quotes, notes, and reviews stay attached to the book, so the idea you saved is one tap away months later.
Support local bookstores while you build your library with the 'find now' feature
Add a book to your library, then find a copy from an independent bookshop instead of defaulting to a warehouse.

- 04
Come back later
Your notes stay with the book. Always.
What Margin isn't
A few things we decided early.
- Not a leaderboard.
- No streaks, no reading challenges, no annual bar chart. Reading isn't a sport, and shame isn't a product feature.
- Not another feed.
- You see other readers' notes when you look for them. Nothing scrolls past you demanding a reaction.
- Not performative.
- Every book, every note, every list has a privacy toggle. Share what you want seen. Keep the rest for yourself.
- Not a Goodreads clone.
- Star ratings and shelves are fine. We're more interested in the sentence that changed your mind on page 212.
The idea behind Margin
Margin isn't about remembering what you read. It's about remembering what you thought while reading it, and discovering what those ideas mean to other people.
Trying the beta?
Margin is being built in the open. If you've been using the app, tell us what's working and what isn't, we read every note.
