Build quizzes from your own material

Most apps to make your own quizzes still ask you to type each question and answer by hand, which can take longer than the studying itself. DeckOwl works from material you already have: upload notes, slides or a PDF, and it writes the questions for you.

Start from notes, slides or PDFs instead of a blank page
Mix multiple-choice, true/false and short answer questions in one quiz
Read a short explanation for every answer, right or wrong
Export to PDF or DOCX on paid plans, or to QTI 2.1 and Moodle XML on Pro

Example cell biology quiz questions

Which organelle produces most of a cell's ATP through cellular respiration?The mitochondrion. The citric acid cycle and oxidative phosphorylation take place there, and they generate most of the cell's ATP.

True or false: ribosomes are surrounded by a phospholipid membrane.False. Ribosomes are not membrane-bound; they are made of rRNA and protein.

Which organelle in plant cells, but not animal cells, captures light energy for photosynthesis?The chloroplast. It contains chlorophyll, which absorbs light to drive the reactions that build sugar.

What is the main job of the Golgi apparatus?It modifies, sorts and packages proteins and lipids for transport. Cells rely on this step to deliver molecules to the right place.

What does the nucleolus assemble?Ribosomal subunits. It combines rRNA with ribosomal proteins before the subunits leave the nucleus.

Questions from your own material

Upload a PDF, DOCX, PPTX, plain-text notes or a photo of a page. The quiz is built from what you actually need to learn.

Three question types

Choose multiple-choice, true/false or short answer questions, or mix them in one quiz so practice matches how your course tests you.

Explanations for every answer

Each question includes a short explanation, so a wrong answer teaches you why instead of only marking it wrong.

How it works

Upload your material

Add a PDF, Word file, slide deck, notes or a photo of a page. Text in images is read with text recognition.

Pick the question types

Select multiple-choice, true/false, short answer or a mix, then generate the quiz in one step.

Study and review

Take the quiz in your browser, read the explanations, and return to missed questions until they stick.

Each question comes with an explanation, so a wrong answer becomes a lesson. You can choose multiple-choice, true/false or short answer, then check the set before you study it. Paid plans add PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML for course platforms.

Frequently asked questions

How many questions should a practice quiz have?

Ten to twenty questions is a good range for one study session. Shorter quizzes are easier to repeat, and repeating missed questions is where most of the learning happens.

How can I check that the quiz questions are accurate?

Compare a few questions against your source material and read the explanations, which point back to the reasoning behind each answer. Remove or edit any question that does not match your course content.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser. Exporting files requires a paid plan, and no credit card is needed to start.

Which file types can I upload?

You can upload PDF, DOCX, PPTX, plain-text notes and images such as photos of pages, which are read with text recognition.
