Smart Notifications
Never miss a review with customizable reminders, quiet hours, and overdue alerts tailored to your schedule.
POWERED BY THE FSRS ALGORITHM
Brainbank uses the Free Spaced Repetition Scheduler (FSRS), a modern machine learning-based algorithm that adapts to your unique learning patterns for optimal retention.
Personalized Learning Paths
Each card maintains separate difficulty and stability metrics that evolve with every review. Cards progress through distinct states (New → Learning → Review → Mastered) with the algorithm detecting at-risk cards before you forget them.
Intelligent Prediction & Scheduling
FSRS analyzes your performance across four confidence levels (Again, Hard, Good, Easy) to predict optimal review times. Reviews are scheduled with precision based on memory stability and retrievability, ensuring you see cards at the perfect moment before forgetting.
Complete Customization
Customize learning steps, graduating intervals (1-30 days), maximum intervals (30-730 days), and interval multipliers for Hard/Easy ratings. Fine-tune 19 FSRS weights (w0-w18) that control memory prediction, difficulty calculations, and retention optimization.
TRACK YOUR LEARNING JOURNEY
Study Activity Calendar
Visualize your consistency with a color-coded heatmap showing daily study sessions over weeks and months, helping you maintain momentum and identify patterns in your learning routine.
Memory Curve Insights
Track how well you retain information over time with FSRS-based retention graphs, revealing the effectiveness of your spaced repetition and when knowledge consolidates into long-term memory.
Performance Analytics
Monitor your learning velocity with detailed metrics including retention rate, cards reviewed, average difficulty, and mastery progress across all your decks and study sessions.
