CanQuiz

CanQuiz is for the moment you have the material and no way to test yourself on it. A folder of notes, the PDF the lecturer uploaded, photos of a notebook, the slides from a class exported as PDF, a web page, a YouTube link. It reads what you give it and writes questions with the options and an explanation for each answer. Up to five files go in at once and come out as one quiz, so your notes and the lecture slides end up in the same place.

Practice is the part that matters. You take the quiz, you see what you got wrong, and you can retry only those. What you save goes into a review queue (beta) that tells you what is due today and spaces the rest out, so a subject stays alive between the day you studied it and the day of the exam.

Quizzes are private until you decide otherwise, and there are two ways to hand one over. A link, which opens without an account. Or a file: a quiz exports as a small .json that opens in CanQuiz without an account, which is how a lot of them travel, sent over a group chat like any other attachment. There is CSV as well, and a text export that imports straight into Anki. If you made a quiz in ChatGPT, paste its answer into CanQuiz and it opens as a playable quiz.

You can also work from someone else's. Public quizzes are browsable, and duplicating one puts your own copy in your account: edit it, cut what is not on your syllabus, add your own questions. If the person who published it fixes an answer later, your copy says so and you choose whether to take the change.

If you would rather not generate anything, you can write the questions yourself: single choice, multiple choice, true or false, short answer, or an open question the AI grades.

The AI comes with the account: 20 generations a month, with no API key and no card. If you need more, you can add your own Google, Anthropic or OpenAI key, which stays in your browser.

What it will not do: read .docx files or audio, or put a picture inside a question. Questions are text, which is what lets a whole quiz fit in a file small enough to send over a chat. It runs in a browser and installs as an app on a phone.
