## What is Margin?

Margin is where what you read goes when you're done reading it.

Most of what survives a book isn't its plot — it's the sentence you underlined
and half-forgot. In a paper book, that sentence stays trapped on the page.
Margin gets it out.

CAPTURE FROM PAPER
Photograph a page and Margin reads the text off the photo, so you can keep a
passage from a physical book without typing it out. Everything happens on your
device.

EVERYTHING IN ONE PLACE
Every highlight, note, and passage you save collects in Marginalia — one feed
across your whole library, searchable by passage, note, title, or author.
Filter to just highlights or just notes, or group by book.

TRACK WHAT YOU'RE READING
Keep your library organized by what you're reading, what you've finished, and
what's next. Group books into collections. Set a yearly reading goal and build
a reading streak.

READ PDFS AND EPUBS
Import your own PDFs and EPUBs and read them in the app, with highlights and
notes saved alongside everything else.

YOURS, AND PRIVATE
There is no account and no sign-up. Your library lives on your device and syncs
through your own iCloud, so it follows you to a new phone. Nothing is stored on
our servers — we can't see your books or your notes.

FREE, WITH NO CATCH
Every feature is included. No subscription, no paywall, no ads.

An optional AI reading companion is available if you supply your own OpenAI API
key. It stays off until you do.
