Why teachers start from their own lesson material

A good online quiz game maker for teachers should begin with the material you already have, not a blank page. Your slides and notes already contain the facts you want students to remember, so the questions stay tied to what you taught.

  • Generate from PDFs, slides, DOCX files, text notes or photos of pages
  • Multiple-choice, true/false and short-answer questions with explanations
  • Study in the browser on the free plan, with 3 generations per month
  • Paid plans add unlimited generations and export to PDF, DOCX, Anki and CSV
Example middle school science quiz questions on photosynthesis
Which gas do plants take in for photosynthesis?Carbon dioxide. Plants combine it with water using light energy to make glucose.
True or false: photosynthesis takes place in chloroplasts.True. Chloroplasts contain chlorophyll, which absorbs light energy for the reaction.
What sugar do plants produce during photosynthesis?Glucose. Plants use it as stored chemical energy for growth and cell respiration.
Why do most leaves look green?They reflect green light. Chlorophyll absorbs red and blue light more strongly.
Where does the oxygen released in photosynthesis come from?Water. Water molecules are split during the light reactions, and oxygen is released as a byproduct.

Three question types

Generate multiple-choice, true/false or short-answer questions, and choose the mix that fits your lesson.

Explanations for every answer

Each question comes with a short explanation, so students learn why an answer is right, not just which one it is.

Works from your own material

Start from your slides, handouts or photos of pages. Text in images is read with text recognition.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes or a photo of a page.

Pick question types

Choose multiple-choice, true/false or short-answer questions, then generate the set.

Review and use in class

Edit questions, study them in the browser, or export them if you are on a paid plan.

DeckOwl reads your upload and writes questions with answer choices and explanations. You can review each one before it reaches students, which keeps the quiz accurate and matched to your course.

If you need to move questions into another system, paid plans export to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML for teachers who run quizzes in a learning management system.

Frequently asked questions

How many questions should a classroom quiz have?

Most classroom quizzes work well with 10 to 20 questions that cover one lesson or unit. Shorter sets make it easier to repeat the quiz and check what students have retained.

What makes a good quiz question for a game format?

Good questions have one clearly correct answer and distractors that reflect common mistakes. Short, specific wording helps students answer quickly during a round.

Can I export quizzes to Moodle?

Moodle XML and QTI 2.1 export are available on the Pro plan at $14.99 per month. PDF, DOCX, Anki and CSV export are included with the Plus plan.

Is there a free plan for teachers?

Yes, the free plan includes 3 generations per month and studying in the browser. Exports require a paid plan, and students get 40% off with a school email.
