Your learning preferences

Spaced review uses FSRS for words, phrases, and forms you’ve missed, once you learn them, and items you choose to keep reviewing. Other understood items stay unscheduled. Use the blue marking tool or the vocabulary library to choose reviews. Settings apply to future reviews. Reviews become due at the start of their calendar date in your device’s local time; there is no review hour to wait for.

Personalize FSRS

Fit the review scheduler to how you remember words, phrases, and grammar. Optimization runs in your browser using WebAssembly.

Using the default FSRS scheduler.

Loading your review history…

Fitting needs at least 50 recorded FSRS reviews, including 8 reviews on later days. Learning repetitions and extra practice on the same day do not count. Keep learning and return when your reviews are due.

Changes apply when you next review a concept; existing due dates stay in place. Your settings and review history save with your progress and sync when you’re signed in.
