Game-style review without building the quiz by hand

Teachers and students who like the pace of a Kahoot-style round often want that format for Gimkit and Kahoot-style quiz review, but writing good questions takes longer than the review itself. DeckOwl reads your own notes or slides and writes multiple-choice, true/false and open questions with explanations, so the practice matches what your class actually covers.

  • Questions are generated from the files and notes you upload
  • Multiple-choice, true/false and open questions each include an explanation
  • Free plan includes 3 generations per month with browser study
  • Plus and Pro add exports to PDF, DOCX, QTI 2.1 and Moodle XML
Example renewable energy quiz questions
Which renewable source produces electricity directly from sunlight using photovoltaic cells?Solar photovoltaic energy. Photovoltaic cells convert light directly into electricity without a heat cycle.
True or false: geothermal power plants can run day and night because they draw on underground heat.True. Geothermal reservoirs supply steady heat that does not depend on weather or time of day.
What is the first energy conversion in a wind turbine?Kinetic energy of moving air becomes mechanical rotation of the blades. A generator then converts that rotation into electricity.
Why is hydropower classed as a renewable source?The water cycle replenishes the water that flows through turbines, so the source is not used up by generating power.
When is biomass considered a renewable energy source?When it is harvested no faster than it regrows, because new plant growth absorbs the carbon released when the biomass burns.

Questions from your material

Upload PDFs, DOCX files, PPTX slides, plain text or photos of pages, and get questions drawn from what you actually studied.

Three question formats

Multiple-choice, true/false and open questions, each with an explanation so you learn why an answer is right or wrong.

Exports when you need them

Export to PDF or DOCX on Plus, and to QTI 2.1 or Moodle XML on Pro for courses that run on an LMS.

How it works

Upload your material

Add a PDF, slides, notes or a photo of a page. Text recognition reads the content for you.

Choose a question type

Pick multiple-choice, true/false or open questions and generate a set from your own content.

Practice and review

Work through the questions in the browser, read the explanations and repeat the ones you missed.

DeckOwl does not host live game rounds with a room code. What it does is produce the question bank: you review it in the browser, see why each answer is right, and keep returning to the items you missed. Because the questions come from your material, you can check them against the source before you use them.

If you need the same questions in another system, the Plus and Pro plans add exports. Plus includes PDF, DOCX, Anki and CSV, and Pro adds QTI 2.1 and Moodle XML for course platforms.

Frequently asked questions

How many quiz questions should I write for a renewable energy unit?

Aim for enough questions to cover each source in your unit at least twice, usually 15 to 25 across solar, wind, hydro, geothermal and biomass. Spreading them out this way tests recall of each concept instead of repeating one idea.

How do I study renewable energy sources with quizzes?

Start with true/false questions to check basic facts, then move to multiple-choice questions that compare sources. Read the explanation after every miss and retry those questions a day or two later.

Can I export these quizzes to Moodle?

Yes, Moodle XML export is available on the Pro plan at $14.99 per month. Exports to PDF, DOCX, Anki and CSV are available on Plus at $99.90 per year or $9.99 per month.

Is there a free plan?

Yes. The free plan includes 3 generations per month and browser study, with no card needed to start. Exports are not included on the free plan.
