Margen

You underline a passage that moves you, close the book… and months later you can't even remember what it was about. That's what Margen is for: to save what a book left you with and bring it back to you when you've forgotten it.

It's not a social catalog or a network of readers. It's your reading memory.

THREE WAYS TO TAKE NOTES

Each note has its own nature, and Margen treats them differently:

- Quotes — the exact passage, saved with its page number and highlighted just like in the physical book.

- Ideas — the important points, summarized in your own words.

- Reflections — what it made you think or feel.

All formats support Markdown and tags for easy retrieval.

YOUR HIGHLIGHTS TODAY

Every day, Margen retrieves one of your quotes and displays it when you open the app. You can activate a daily notification at the time of your choice. It's the difference between highlighting and remembering.

LIBRARY WITH COVERS

Type the title and Margen automatically fills in the cover, author, and year. Organize your books into those you're currently reading, those on your reading list, and those you've finished, and rate them from one to five.

SHARE YOUR QUOTES AS IMAGES

Turn any note into a social media-ready image, complete with Margen's typography and highlighting. One tap and it's in your stories.

WHAT TO READ NEXT?

Margen suggests books based on your ratings and tags. The content of your notes never leaves your device for this: only a summary of your reading preferences travels.

READING SESSIONS

A 25-minute reading timer with a 5-minute break helps you get into a rhythm when it's hard to start. Margen tracks how much you've read each week.

TO-DO NOTES

Note the topics you want to revisit—reread a chapter, look up the author, compare an idea—with an optional deadline and linked to the book that sparked them.

WORKS OFFLINE, ALWAYS

Margen saves everything on your device. You can read and write on the subway, on a plane, or in the countryside, without a signal and without waiting for anything to load.

An account is optional. If you activate it, your notes sync across your devices; if not, the app works perfectly fine. No passwords: log in with a code sent to your email.

YOUR DATA IS YOURS

- No ads.

- No analytics or tracking.

- Download a complete backup whenever you want.

- Export notes from any book as a text file, ready for Obsidian, Notion, or wherever you prefer.

Margen doesn't lock you in: you can take what you write with you.

WHO IS IT FOR?

For essay readers who want to retain what they've learned. For those who underline passages in novels and want to revisit those lines. For students, for those who keep a reading journal, and for anyone who has ever felt a book slip away from their memory.
