Smart distractors
AI generates plausible wrong answers that test understanding rather than mere recall.
Adaptive difficulty
Questions adapt to your performance — harder when you are sharp, gentler when you stumble.
Performance analytics
Track accuracy, speed, and knowledge gaps with detailed session statistics.
Multiple formats
Multiple choice, true / false, fill-in-the-blank, and matching — generated automatically.
Memory
Spaced repetition, intelligently scheduled.
Review at the right moment — neither too soon nor too late. The algorithm does the bookkeeping; you simply show up.
Forgetting-curve optimization
Drawing on Ebbinghaus, reviews are scheduled just before recall slips — strengthening long-term memory.
Adaptive intervals
Stubborn cards return more often. Mastered cards quietly recede into the background.
Long-term retention
Spaced repetition can improve retention by up to 200% compared with traditional cramming.
Time-efficient learning
Fewer minutes spent reviewing. More minutes spent reading something new.
