The best AI tools to turn your notes into practice tests (2026): 6 compared

Turning your notes into exam questions is one of the best ways to study: it forces you to retrieve information instead of rereading it. Doing it by hand takes hours. With AI, seconds.

The catch is that almost every tool "generates quizzes", and they're not all equally useful for passing. Here are six, what each does well, where they fall short and, at the end, how to tell whether the questions an AI gives you are any good.

Disclosure: ExamFlow is ours. It's on the list with its cons, like the rest.

What a good notes-to-test AI should do

Before the list, the criteria. A useful tool for this should:

1. Only ask about your notes. If it mixes in what it knows from the internet, you get tested on things that won't be on the exam.
2. Read your material as it is. PDF, Word, photos of the textbook and, if you write by hand, handwritten notes.
3. Give believable wrong answers. A quiz with three absurd options and one right one measures nothing.
4. Explain every answer, especially the ones you miss.
5. Go beyond multiple choice if your exam does: short answer, essay, case studies.
6. Ask you again what you got wrong. A quiz that forgets your mistakes has you reviewing what you already know.

No free tool ticks all six. It depends on which ones matter to you.

1. ExamFlow: your syllabus by topic, with mistakes that come back

Best for: university and long syllabi with an exam date.

You upload your notes (PDF, Word or photos, handwritten included) and ExamFlow organizes them by topic. Then you pick one, several or all topics and generate an AI exam: multiple choice, true/false, short answer, essay or case studies. Questions come from chunks of your notes, not from the internet.

• It grades essay answers with an indicative score and explains what was missing.
• The questions you miss come back in later exams until you get them right.
• Progress per topic, so you see what you're weakest at.
• For civil service candidates, exam pages with the official syllabus.

Cons: it's paid after the free 14-day trial (no card). An exam of up to 15 questions costs 12 credits, and the cheapest pack is 350 credits for a one-off €4.99. If you only need a quick quiz on one topic, the free options are enough. See pricing.

2. Gemini Notebook (formerly NotebookLM): free and grounded in your sources

Best for: people already using NotebookLM to read who want to practice without switching tools.

Google renamed NotebookLM to Gemini Notebook in July 2026. Since September it generates multiple-choice quizzes and flashcards from the sources you upload, and you can ask the chat how you did. Questions are based on your documents.

Cons: multiple choice only for now (Google has announced short answer and fill-in-the-blank), with no graded essays. What you miss doesn't come back on its own in the next quiz. More in NotebookLM alternatives for studying.

3. ChatGPT: the most flexible, if you know how to ask

Best for: a quick quiz on a specific topic, in the exact format you want.

Upload the PDF or paste the text and ask for the quiz. Study mode, also available on the free plan, asks you questions one at a time and explains your mistakes. With good instructions it handles almost any format.

A prompt that works:

Make me a 10-question quiz on the text I'm sending. Use only information from the text. Four options per question, all believable. Don't show the answers until I've answered all 10. Then grade me and explain each mistake, quoting the paragraph from the text.

Cons: every conversation starts from scratch, so your syllabus isn't saved by topic and nothing tracks what you got wrong. We explain it in Is ChatGPT good for studying?.

4. Quizlet: tests and flashcards in one place

Best for: high school and languages.

Its AI tools create flashcards and practice tests from your notes or PDFs, which you then review with its study modes. It has millions of sets made by other students.

Cons: the most useful AI features are on the paid plan, and the format is built for short questions. For essays or case studies it falls short. We compare it in ExamFlow vs Anki vs Quizlet.

5. Knowt: the free Quizlet alternative

Best for: anyone who wants practice tests from PDFs or lecture videos without paying.

It generates flashcards and practice tests, and its free plan includes unlimited Learn mode and spaced repetition.

Cons: it's built mainly for US students. It works for other exams, but there's less ready-made material.

6. Wayground (formerly Quizizz): if you're a teacher

Best for: teachers who want to turn a lesson into a class quiz.

Quizizz has been called Wayground since June 2025. Upload a PDF or paste a web page and its AI builds the quiz, which you then run in class as a game.

Cons: it's made for the classroom, not for a student preparing alone. If you're a student, any of the others fits better.

Summary table

How to tell if an AI-generated quiz is any good

Whichever you use, check these five things on the first quiz:

1. Does every question come from your notes? If you see facts that aren't there, the tool is pulling from the internet.
2. Are the wrong answers believable? If you can get it right by elimination, the quiz isn't measuring what you know.
3. Does it ask about what matters? A good quiz targets key concepts, not the footnote trivia.
4. Are the right answers actually right? Check two or three against your notes. AI makes fewer mistakes when it works from your material, but it still makes them.
5. Does it look like your real exam? If your exam is essay-based, practicing only multiple choice leaves you half-prepared.

Which one to pick

• A one-off quiz on one topic: ChatGPT or Gemini Notebook, free.
• An exam with many topics: ExamFlow, because it keeps the syllabus by topic, grades essays and repeats what you miss.
• Memorizing vocabulary or definitions: Quizlet or Knowt.
• Building a quiz for your class: Wayground.

Bottom line

Almost every tool can turn notes into a quiz now, and for a single topic the free ones are enough. The difference shows up with long syllabi: keeping your material by topic, grading essays and making what you miss come back. That's what ExamFlow is built for, and you can try it free with your own notes.
