Science-backed algorithm that optimizes when you review each word
Spaced repetition is a learning technique proven by cognitive science to dramatically improve long-term memory retention. Instead of cramming all at once, our AI algorithm determines the optimal time to review each vocabulary word based on your mastery level.
The system tracks how well you know each word and automatically schedules reviews right before you're about to forget. This "forgetting curve" optimization means you spend less time studying while remembering more words for longer periods.
Our algorithm monitors your performance on each word, tracking correct answers, review frequency, and confidence levels.
Words you struggle with appear more frequently, while words you've mastered show up at increasingly longer intervals.
The system continuously adapts to your learning pace, ensuring you review words at the perfect moment for maximum retention.
Once a word moves to long-term memory, the algorithm spaces out reviews to months, ensuring permanent retention with minimal effort.
Based on your mastery level, words are reviewed at strategic intervals:
New Words
Review within 1 day
Learning
Review every 3-7 days
Familiar
Review every 2-4 weeks
Mastered
Review every 1-3 months
