How many questions are generated?

VoiceBrief typically generates 10-20 questions per document, covering the most important concepts and details.

Can I generate more questions?

You can regenerate quizzes to get fresh questions. Each generation may produce different questions from the material.

How does spaced repetition work?

Questions you answer correctly appear less frequently over time (1 day, 6 days, etc.). Questions you miss reset to daily review. This optimizes long-term memory.

Are the questions good quality?

Questions are generated by GPT-4o, which understands context and creates meaningful questions. They test comprehension, not just surface-level recall.
