Review at the right time
Yuzu Dojo schedules your reviews based on what you remember, so you always know what to practice next.
See it stick
Every word climbs five mastery levels — from New to Known — as you review.
Spaced repetition, done right
An algorithm that knows
when you'll forget.
Yuzu Dojo schedules every review with FSRS — a modern memory model that predicts your forgetting curve per word. You review just before you'd forget, and nothing more.
