Anki vs MarginNote
Side-by-side comparison of features, pricing, ratings, and alternatives.

Anki is a flashcard application built around spaced repetition, using an algorithm to schedule reviews so learners spend more time on challenging material and less on cards they already know well. It is free and open source on desktop (Windows, macOS, Linux), with source code publicly available on GitHub and an extensible add-on ecosystem built by the community.
MarginNote is a study and knowledge-management app for Mac and iPad, positioned as a place 'where deep reading leaves a trace.' It integrates PDF/EPUB annotation, mind mapping, and an FSRS-based spaced-repetition flashcard system so that highlights and notes automatically become study cards across multiple linked formats.
