Which drug class is first-line for stable chronic angina?
An AI quiz generator reads your lecture or study material and writes practice questions for you. Distill’s quiz engine goes beyond generic question generation — it pulls the content that was actually emphasized (definitions, cause-and-effect relationships, numeric thresholds, named entities), writes questions calibrated to exam difficulty, and provides full explanations tied back to the source material.
You choose the mix: straight multiple choice for memorization, short-answer for recall practice, case-based vignettes for clinical reasoning (or legal analysis, or business cases), and true/false for quick fire revision. Every question comes with a rationale, a confidence score, and a link back to the exact timestamp or page where the answer was taught.
Quizzes are timed, self-scoring, and tracked over time — so you can see which topics you keep missing and which concepts have finally clicked. Practice questions from notes, automatically: the self-test loop every learning-science study recommends, without the prep work.
Not another note app. A real shortcut from lecture to long-term memory.
Before: Generic quiz generators spit out trivia-style questions that don’t match your exam’s style.
With Distill: Distill matches question style to your subject — USMLE-style vignettes, MBE fact patterns, SAT-style reasoning, or GCSE-style short answer.
Before: Getting a question wrong doesn’t teach you anything unless you know *why*.
With Distill: Every question shows the correct answer, why the distractors are wrong, and a link to the exact spot in the lecture where the concept was taught.
Before: You can’t tell which topics you actually understand until you’ve failed the exam.
With Distill: Distill tracks accuracy by topic over time and auto-generates weakness-focused quizzes so you study what you’re weakest on, not what feels easy.
From first tap to ready-to-study — a few minutes, max.
Any lecture, PDF, or set of notes you’ve processed in Distill. You can combine multiple sources into one quiz.
Choose length (5, 10, 25, 50 questions), question types, difficulty, and exam style. Distill also has one-tap presets: ‘mid-term prep’, ‘exam simulator’, ‘quick revision.’
Answer in-app with a timer. Each question is scored, explained, and tagged with the concept it tests.
See your performance by topic, and generate a follow-up quiz focused on your weakest areas.
Distill matches the format of the exam you’re actually sitting — not a generic quiz template.
Most ‘AI quiz’ tools were built for teachers making homework. Distill is built for students taking exams.

Jenna takes 10-question FAR quizzes on her phone during her subway ride. The app tracks which FASB standards she keeps missing and loads the next quiz full of them.
“The USMLE-style vignettes are genuinely good. Distractors are plausible, the explanations cite the right pathways. I cancelled my Kaplan Qbank subscription.”
“I was skeptical an AI could match the style of A-level past papers. It can. My teacher couldn’t tell which quiz was AI and which was from the exam board.”
“Weakness-focused quizzes saved my CFA prep. I stopped wasting time on the stuff I knew and drilled the exact concepts I was failing.”
Questions are written by a model specialized for assessment, then verified against the source for factual consistency. In our internal testing, 96% of questions are factually correct and 91% have plausible distractors. You can flag any bad question and it auto-rewrites.
Yes. Distill has a shareable quiz mode — generate a quiz, click ‘share with class’, and your students get a link. Teacher plans include student analytics.
Yes. Short-answer responses are graded by an AI rubric that accepts paraphrases and synonyms. Grading is transparent — you see exactly what the rubric looked for.
Yes. Export to Anki (as cloze cards), Kahoot, Google Forms, PDF, or CSV. Quizzes can also be imported into your LMS (Canvas, Moodle, Blackboard) as QTI.
Each preset is a prompt profile tuned to match that exam board’s style — USMLE step 1 questions are long-form vignettes ending in ‘what is the most likely…’, SAT reading is evidence-based, MBE is fact-pattern analysis. We iterate these quarterly.
Tap ‘⚠ report’ and it auto-rewrites with a second model. If you’re still unhappy, you can edit the question directly — Distill learns from the edit.
Distill is more than ai quiz generator— it's a whole studio for your lectures.
