Roediger and Karpicke (Science, 2006) found students who practiced retrieval through testing retained 50% more material than those who re-read their notes.
Every time you attempt retrieval during a quiz, you strengthen the neural pathways tied to that knowledge — even when you get the answer wrong. GoodOff amplifies this by feeding missed questions back into your FSRS review queue, so the system surfaces them again at the optimal moment for memory consolidation. Read the original study.
Upload any study material (PDF, slide deck, lecture video, your own notes) and the AI extracts the key concepts, writes multiple-choice questions, and includes plausible wrong answers (distractors) that test real understanding. Each question comes with an explanation so you learn from misses.

(2) Adaptive difficulty: GoodOff escalates questions when you streak and backs off when you struggle. (3) Spaced repetition: missed quiz questions feed back into your FSRS review queue automatically.
Yes. Generated quizzes can be shared by link with study groups. Everyone runs the same quiz, scores roll up to a shared leaderboard.
Multiple-choice with four answer options today, including AI-generated distractors designed to test real understanding. True/false and fill-in-the-blank are on the near-term roadmap.
