Marginalis

Every great book leaves a mark. Marginalis makes sure you never lose it.
A reading journal for physical book readers — capture highlights with Live Text, organise your library, and revisit the passages that changed how you think.

Capture quotes without the friction
Point your camera at any page. iOS Live Text does the rest. Your highlight is captured in seconds — no typing, no losing your place, no forgetting which page it was on.
Prefer to type? Every note has space for the quote, your own comment, a page number, and tags you create yourself.

Five kinds of notes, because not every thought is the same
Quote. Idea. Question. Reaction. Summary. Each note type gives your thinking room to breathe — and makes it easy to find exactly what you were looking for when you come back.

Your library, the way you actually read
Organise books across Reading, Up Next, Wishlist, and Finished. Add any title by scanning its barcode, searching by name, or entering it manually. Cover images fetch automatically.

Share the passages that moved you
Turn any note into a beautiful image card — paper or editorial style, portrait or square format. Edit the text inline, then share anywhere. Because some quotes deserve more than a screenshot.

Understand your reading life
A heatmap of your annotation activity. Note type breakdowns. Favourite authors. A tag cloud built entirely from your own words. Marginalis reflects your reading back to you in ways that are actually interesting.

AI Book Summary — on your device, privately
On supported devices, Marginalis can generate an intelligent summary of your notes for any book — powered by Apple Intelligence. Processed entirely on your iPhone. Your words never leave your device.

Your favourite quotes, on your Home Screen
The Marginalis widget brings your reading life to your iPhone's Home Screen. A randomly chosen quote or highlight from your library — refreshed daily. A small reminder of why you read.

Seamless iCloud sync
Your library and notes sync automatically across all your iPhone and iPad devices via iCloud. Private, seamless, and requiring nothing beyond your Apple ID.

Built for privacy, from the ground up
No account required. No subscription. No analytics. No advertising SDKs. Your library, your notes, and your reading life belong entirely to you — stored on your device, synced only if you choose.
