Marginalis

Every great book leaves a mark. Marginalis makes sure you never lose it. A reading journal for physical book readers — capture highlights, 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. Prefer to highlight in other apps? Send any selected text straight to Marginalis from Kindle, Apple Books, Safari, or anywhere with a share sheet. 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. Browse by genre or reading status. 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. Edit inline, then share anywhere. Because some quotes deserve more than a screenshot. Explore your reading with AI Synthesis lets you have a real conversation with your reading. Select books or tags, then ask anything — what themes keep coming back, what tensions you noticed, what remains unresolved. Your reading assistant answers from your own notes, citing exactly where each idea came from. When something is worth keeping, save it as a permanent insight. On supported devices, Marginalis can also generate an intelligent summary of your notes for any book — powered by Apple Intelligence, processed entirely on your iPhone.
