Set the level, chapter count (auto or manual), and content depth (standard or extended), and toggle whether to include quizzes and a final exam.

Review before you keep

A review drawer shows the just-generated cards, flags likely duplicates, and lets you delete the weak ones before you save.

A spaced-repetition engine that adapts

Review with a proven scheduler that brings cards back at the right moment and retires what you have mastered.

Rate and reveal

Tap to reveal, then rate Again, Hard, Good, or Easy by button, keyboard, or swipe, with next-interval previews.

SM-2 scheduling

An Anki-style SM-2 scheduler moves cards through learning, review, and relearning, with short in-session learning steps.

Adaptive retirement

Cards you reliably recall at a long interval retire automatically, so mastered material stops crowding daily reviews.
