Make exam-style quizzes from your notes and practice until you know them
Upload a PDF or a photo, paste your notes or write the questions yourself. CanQuiz quizzes you like the real exam and makes you retry what you miss, and you share the quiz with a link that opens without an account.
As the exam gets close, sit a mock exam under its own rules: the time limit, the number of questions and the penalty for a wrong answer.
AI comes with the account, no API key.

Your notes, turned into a quiz
Pick some notes and press the button: what you could be asked turns into questions. With yours, the AI does it.
Handwritten example. With your notes, the AI writes the questions.
Chapter 3 · The cell
The cell is the basic unit of life. Mitochondria produce the cell's energy through cellular respiration. The nucleus holds the DNA and directs the cell's activity. Chloroplasts, found only in plant cells, carry out photosynthesis. The plasma membrane controls what goes in and out.
Sources
Study from your own sources
Keep an exam's PDFs and photos in its folder. They stay there as sources, so you can read them, highlight what matters and ask about anything you don't get.
Reading mode
Each page shows as clean text, and “See original” brings back the page as it looks.
Highlights
What you highlight is saved in its own list, ready to ask about or turn into questions.
Ask your sources
Answers come from the text of your PDFs and cite the page. If your sources don't cover it, CanQuiz tells you.
A quiz from any source
Pick a source or a few highlights and ask for questions on them.
Mock exam
Ready for exam day
Put an exam's quizzes in one folder. CanQuiz sorts them into topics, builds the mock exam with your rules and, once you finish, lets you practice what you missed.
Mock exam
The whole exam under your rules: number of questions, time limit, pass mark and the penalty for a wrong answer.
Results and mistakes
When you hand it in, you see your score against the pass mark and go through every answer. One button starts a practice round on the ones you missed.
Timed practice
A round against the clock for any day of the week. It lives in the folder's practice settings, where you pick the quizzes and how many questions.
Topics
CanQuiz sorts the folder's questions into topics without you writing any list. With an exam date, the folder shows a ring with how ready you are.
Bring what you've got
Notes, PDFs, photos and links
Your notes, a PDF or a photo: CanQuiz turns them into a quiz. No rewriting, no filling out forms.
Your notes
Paste text or what you wrote down in class, or describe a topic in two sentences.
Notes to quizLinks
An article or a Wikipedia page on the topic. Paste the URL and CanQuiz tries to read it; some sites don't allow it, and then you paste the text instead. YouTube videos aren't read.
When you ask for a quiz, you choose the question type, the level and how many questions.

From your chat
Make quizzes and practice them inside ChatGPT and Claude
Ask for a quiz on your topic or your notes and the chat writes the questions. CanQuiz saves them to your account and asks them right there, one at a time, with the explanation for each answer. Then it schedules the review.
In ChatGPT
Add the CanQuiz plugin once and ask with @CanQuiz or just in plain words, with your notes pasted in or the topic's PDF.
In Claude too
Connect your CanQuiz account once, on the web, in the desktop app or in Claude Code. On claude.ai each question shows up in the chat with its options, and when you check yours you see the explanation.
Open questions
Write the answer. The AI grades it.
Nobody gives you options in a written exam. In CanQuiz you answer in your own words and the AI gives you a grade, tells you what's missing and shows you the expected answer.
A grade that explains itself
From 0 to 100 and, if you ask, one sentence on what you missed.
You choose how strict it is
Lenient, normal, strict or examiner, which only passes a near-perfect answer.
With AI or by hand
Ask for open questions when you create a quiz, or write them yourself with their expected answer. They're graded the same way.
How it grades
What is photosynthesis?
Your answer: partial
What's missing: that they use sunlight to turn water and carbon dioxide into glucose and oxygen.
Show expected answerHide expected answer
Expected answer
Photosynthesis is the process by which plants use sunlight to turn water and carbon dioxide into glucose, releasing oxygen.
