About

MargiNotes

Features
Read full description

MargiNotes is a calm reader and note-taking app for PDF, EPUB, and paper books. Its difference is simple: a note can keep a path back to the book it came from. Import a highlight from Kindle or Apple Books, or capture a quote from a printed page. If the matching PDF or EPUB is in your library, MargiNotes can search that book on your device and relink the note to its real place. No guessed links. If MargiNotes cannot find a reliable match, it says so clearly. READ AND CAPTURE • Read PDF and EPUB books with adjustable themes, typography, layout, and reading settings. • Highlight while you read and keep each note with its book. • Capture quotes from printed books with on-device OCR. • Scan a barcode to fill in a paper book's title, author, and cover. • Add comments, tags, and voice notes alongside what you read. FIND YOUR WAY BACK Search inside a book and your own notes appear first, next to the book's own sentences. Search quotes, comments, tags, and transcripts across your whole library, or find a note straight from iPhone search. Ask your notes a question and the answer is built only from them — and always shown with the notes it came from. Writing the answer needs Apple Intelligence; without it, MargiNotes still finds the notes closest to your question. YOUR NOTES, PORTABLE Create shareable quote cards, follow your reading with simple statistics and widgets, and export to Markdown, PDF, or an Obsidian vault where every note keeps its links. PRIVATE BY DESIGN • No account • No ads • No analytics • No cloud AI — text recognition, transcription, and answers run on your device • Sync only through your own iCloud The app never goes online by itself. The one exception is the barcode lookup you start yourself, which sends only the ISBN — and you can switch it off. Your books stay yours. MargiNotes is built to help you remember not only what you saved, but where it came from.
