The Learnie plugin helps learners reinforce knowledge through active recall and spaced repetition by integrating note tracking, flashcard creation, and quiz reviews into their workflow. It allows users to convert notes into trackable learning units, generate revision histories, and create custom questions directly from highlighted text. A diff view helps monitor content changes over time, while daily review sessions and auto-reminders keep the revision routine on track. The plugin also supports flashcard quizzes filtered by tags and provides options to configure notification timings and quiz lengths. All associated data is stored in structured revision and question files linked via frontmatter metadata.
