MarginNote

Where deep reading leaves a trace·marginnote.com

MarginNote is a PDF and e-book study tool where a single highlight becomes a mind-map node and a flashcard. It supports annotation of PDF, EPUB, web pages, and video, with OCR for equations, tables, and handwriting, and offers 10 mind-map layout styles. It includes an FSRS spaced-repetition scheduler for reviewing flashcards and an AI reading assistant that can summarize chapters, surface key terms, and generate quiz questions. It runs on Mac and iPad, with highlights synced across devices via iCloud.
