Example: a quiz on supply and demand
Three questions in the format the tool writes. A full quiz has 10, each with four options.
- When the price of a good rises and nothing else changes, what happens to the quantity demanded? (a) It rises (b) It falls (c) It stays the same (d) Supply falls
- (b) It falls. That's the law of demand: at a higher price, buyers want less, all else equal.
- What is true at the equilibrium price? (a) Supply is zero (b) The government sets the price (c) Quantity supplied equals quantity demanded (d) Demand is at its highest
- (c) Quantity supplied equals quantity demanded, so there's no shortage or surplus pushing the price to move.
- A price ceiling set below the equilibrium price usually causes what? (a) A surplus (b) A shortage (c) No change (d) Higher prices
- (b) A shortage. At the lower price, buyers want more than sellers are willing to supply.
What people use it for
Checking yourself before a test
Upload the chapter you think you know and find out. The questions you miss tell you exactly what to review.
Turning lecture notes into practice
Paste your notes after class. Ten questions take a few minutes and do more than reading the same pages again.
Learning something new
No material yet? Type a topic in Ask AI and use the quiz to find the gaps in what you think you know.
What you get
10 multiple choice questions per quiz, ordered from easy to hard. Each one has exactly four options and one correct answer, and the wrong options are meant to look plausible, so guessing won't get you far. After you answer, a one sentence explanation says why the right answer is right.
When you give it your own material, the AI is told to use only that material. Each run reads up to about 15,000 characters, roughly 2,500 words, so quiz yourself one chapter or lecture at a time.
Why testing yourself works
Pulling an answer out of memory strengthens it more than reading it again. Researchers call this the testing effect, or retrieval practice, and it's one of the most reliable findings in learning science. A wrong answer helps too, as long as you see the correct one right after, which is why every question here comes with an explanation.
The catch is timing. One quiz helps today. Quizzing again a few days later, then again after a longer gap, is what makes it last. That's the part the full lezrn app handles: it turns your material into a course and schedules your reviews for you.

Can AI make a quiz for me?
Yes. Give it your notes, a PDF or just a topic and it writes 10 multiple choice questions with answers and explanations. You need a free lezrn account to make one.
Can I make a quiz from a PDF?
Yes. Upload a PDF with selectable text and the questions come from what's in it. Scanned PDFs don't work, because they have no text for the AI to read.

Does it explain the answers?
Yes. Every question comes with a short explanation that shows up as soon as you pick an answer.
Can I make a quiz from a YouTube lecture?
Yes. Paste the YouTube link once you are signed in to your free lezrn account. A file, pasted text or a web article link work too.
Is it free?
