For active readers
“Not every note needs to become an essay.
Sometimes one honest sentence is enough.”
Margin gives your reading thoughts a permanent home—without giving you another system to maintain.
Inside Margin
Capture quickly while you read. Organize naturally. Return when you are ready.
Quotes, questions, chapter notes, and longer reflections stay connected to the work that inspired them.
Search books, notes, authors, and tags—or return through the day you first captured the idea.
A calm activity view helps you notice your rhythm without turning reading into another performance metric.
A note before the thought slips away.

See what you read and thought on any day.

The Margin philosophy
Your library belongs to you, stored on your device and ready to export.
Margin adds a thoughtful layer around reading without trying to become the main event.
No feed. No notifications. No points to chase. Just your books and what they leave behind.
A record, not a scoreboard
Reading Streak is a soft nudge—not a tiny supervisor. Review active days, notes, books, and words, then click back into the day itself.
