Read a little every day.
Margin is a calm reading-streak app. Track your minutes, read your own books, and let your AI assistant see your library.
iPhone, iPad, and the web. Free to start, no card needed.
A streak that stays kind
Log minutes with a focus timer or by hand, set a daily goal, and watch reading days fill the calendar.
Your books, read here
EPUB and PDF with a page curl that follows your finger, highlights, notes, and your place kept to the sentence on every device.
A library with shelves
Add a book by title, barcode, or a photo of its cover. Sort it into collections and genres.
Ask your assistant
Margin speaks MCP, the open protocol AI assistants use to reach your apps. Connect it once, approve what it may do, then ask about your reading in plain words.

Add Margin as a connector
In your assistant's settings, add a custom connector with this address.
