MarginNote

Overview

MarginNote is a deep reading and learning tool that integrates reading, annotation, note-taking, mind mapping, and spaced-repetition review into a single application. Designed for students, educators, researchers, and professionals, it focuses on knowledge internalization by helping users deconstruct information from documents and reconstruct it through interconnected notes and visual hierarchies. The app implements the SQ3R learning methodology (Survey, Question, Read, Recall, Review) through its Document Mode, Study Mode, and Review Mode.
