Adaptive Spaced Repetition for Maximum Long-Term Retention
Remember more while spending less time reviewing. Notum Learn leverages cognitive science and adaptive memory algorithms to schedule cards right before you are about to forget them.
SM-2 Memory Algorithm
Proven interval expansion based on recall ease, accuracy, and confidence ratings.
Accelerated Exam Mode
Switch to higher-frequency interval curves, preparing for upcoming exams.
Due Queue Optimization
Smart daily batching so you never get overwhelmed by backlog review spikes.
Interactive preview
Test formula typesetting and active recall in your browser.
Simulate grading your recall on a flashcard:
Interval scaled by 2.5x ease factor
The Science of Ebbinghaus Forgetting Curves
Without active retrieval practice, the human brain forgets approximately 70% of new information within 24 hours. Spaced repetition counteracts this forgetting curve by prompting recall at exponentially increasing intervals.
Notum tracks every card's repetition history, interval multiplier, and difficulty rating to ensure optimal memory consolidation with minimal daily study time.
Effortless Confidence Ratings
Mark cards as Hard, Good, or Easy to calibrate your personal retention curve.
Daily Streak & Goal Tracking
Stay consistent with daily review targets and habit streak visualizations.
Customizable SRS Parameters
Adjust initial intervals, minimum ease factors, and lapse penalties to fit your style.
