Why a quiz beats a summary
Reading a summary is still passive learning — you recognize the answers in the text but you couldn't produce them on a blank page. A quiz forces active retrieval: you have to pull the answer from your own memory, which consolidates far more durably.
Meta-analyses on the testing effect show that self-testing is up to 80% more effective than rereading for long-term retention. A 15-minute quiz session beats an hour of skimming a summary.
Three question modes generated
Diane picks the right format from the content, or you can lock a mode:
Multiple choice (MCQ)
Best for nuances and classic traps. AI generates 4 options with one correct answer and plausible distractors pulled from the PDF itself. No silly fake answers — distractors come from related concepts students often confuse.
True/False
Quick format to check your grasp of a statement. Diane mixes verbatim claims from the text with subtly false variations (one word flipped, a date inverted). You sharpen precision fast.
Cloze (fill-in-the-blank)
For lists, dates, formulas, names. A sentence is extracted from the PDF with one key word hidden. You retrieve it. Excellent for factual recall.
Grading isn't just a score
For each missed question, Diane shows the correct answer, the PDF excerpt the question came from (with page number), a short pedagogical explanation, and a link to the matching flashcard if you want to drill that point.
You learn from mistakes, the quiz becomes useful beyond the score itself.
Re-quiz and spaced repetition
Missed questions don't vanish. Diane queues them back at increasing intervals: an hour later, the next day, in 3 days, in a week. After 2-3 cycles, hard questions become solid.
This uses the same FSRS-5 logic as our flashcards: Diane predicts when you'll forget a concept and brings the question back just before. You maximize retention for minimal review time.
Use cases
Students: end-of-chapter quiz before a midterm, self-eval on a dense lecture pack, last-day exam prep. Teachers: generate a quiz from your own slides for your class. Working pros: quick test after a whitepaper or onboarding doc.
A quiz isn't the end goal — it's a diagnostic. In 15 minutes you know what you own and what still needs work, then you focus your study where it pays off.
