RemNote

RemNote is a unique tool designed for learning and long-term knowledge retention, combining a note-taking outliner with built-in spaced repetition flashcards (RemCards). Its portal feature creates non-linear connections, and everything is a 'Rem' (a fundamental unit) that can be linked and nested. It's ideal for students, researchers, and lifelong learners who want to connect notes and actively remember information. It offers a generous free plan with premium features for AI and storage.

It scores well for its specialized, effective fusion of knowledge management and evidence-based learning techniques.
