What this free quiz maker does and doesn't do

Mentimeter is built around live polls for a room full of people, so if you want a free quiz maker for your own revision, DeckOwl starts from a different place: your notes.

Multiple choice, true/false and short-answer questions
Explanations for each answer
3 free generations a month, studied in the browser
PDF, DOCX, Anki and CSV export on Plus

Questions from your material

Upload a PDF, DOCX, PPTX, text file or a photo of a page and get multiple-choice, true/false or short-answer questions.

Explanations on every answer

Each question comes with a short explanation, so a wrong answer also teaches you why it was wrong.

Free to start

The free plan includes 3 generations a month and studying in the browser. No credit card needed.

How it works

Add your material

Upload a PDF, slides, a Word file or notes, or snap a photo of a page.

Pick a question type

Choose multiple choice, true/false or short answer for the quiz you want.

Study and review

Take the quiz in your browser, then read the explanations for anything you missed.

DeckOwl reads your uploaded material and writes the questions for you. The free plan includes 3 generations a month and studying happens in the browser, while exports to PDF, DOCX, Anki or CSV require a paid plan.

If you need real-time audience voting for a class, this is not that tool. It is built for individual practice, so the value is in turning your own reading into questions you can answer and check.

Frequently asked questions

How many practice questions should I answer in one sitting?

Most people do better with short sessions of 10 to 20 questions than one long run, because you can review each explanation before moving on.

Is quizzing yourself better than rereading notes?

Answering questions from memory tends to work better than rereading, because it forces recall. Review the explanation for every miss and retry those questions later.

Can DeckOwl run a live quiz for a class?

No. DeckOwl makes quizzes for individual study and does not run live audience voting. Teachers who need that should use a live polling tool alongside it.

Does the free plan let me export my quiz?

No. The free plan lets you study in the browser with 3 generations a month. Exports to PDF, DOCX, Anki or CSV are included on Plus, and QTI and Moodle XML export are on Pro.
