Turn quick facts into lasting knowledge with intelligent spaced repetition. Add short notes or discoveries in seconds, tag them by topic, and let smart scheduling adapt to how well you remember each one.

Review smarter, not harder — the app automatically spaces reviews for maximum retention, highlighting weak spots and tracking your progress through detailed insights and streak stats. Flexible modes let you focus by topic, time, or cards due for review, while secure backups and sync keep your knowledge safe and accessible everywhere.
