Practice quizzes from your own course material

Students who look for a Canvas quiz browser extension usually want one thing: a way to rehearse questions before the graded attempt. DeckOwl takes a different route. It is a web app you open in your browser, not a plug-in that sits inside Canvas, so it does not change your Canvas quizzes. You upload your own PDFs, slides, DOCX files, plain notes or photos of pages, and it writes multiple-choice, true/false or short-answer questions with explanations.

Questions are generated from the files you upload, not from a shared bank
Each answer includes an explanation of why it is correct or incorrect
The free plan studies in the browser; exports require Plus or Pro
Students with a school email get 40% off Plus or Pro

Example intro biology practice questions

Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which generates most of the cell's ATP.

True or false: Osmosis moves water from a region of lower solute concentration to higher.True. Water moves toward the side with more solute, where free water molecules are fewer.

What is the role of DNA polymerase during replication?It adds complementary nucleotides to a new DNA strand, building it in the 5' to 3' direction.

Why does an enzyme lose activity above its optimal temperature?Heat denatures its three-dimensional shape, so the active site no longer fits the substrate.

Which phase of mitosis lines chromosomes up at the cell's equator?Metaphase. Spindle fibers attach to the kinetochores and align the chromosomes along the metaphase plate.

Built from your material

Upload PDFs, DOCX files, PPTX slides, plain notes or photos of pages. Text recognition reads the photos.

Explanations for every answer

Each question comes with an explanation so you can see why the right choice is right and the others are wrong.

Exports when you need them

Study in the browser on the free plan. Plus adds PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export.

How it works

Upload your course material

Add the readings, lecture slides or notes your Canvas quiz will cover.

Choose question types

Practice and review misses

Answer the questions, read the explanations and come back to the ones you missed.

The free plan gives you 3 generations per month and browser study with no exports. Plus, at $39/year or $7.99/month, includes unlimited generations and PDF, DOCX, Anki and CSV export. Pro at $14.99/month adds a stronger AI model, bulk upload, and QTI 2.1 and Moodle XML export. Students with a school email get 40% off, and no credit card is needed to start.

If your instructor shares a question bank, generate your own practice set from the assigned readings instead of memorizing the exact wording. Practicing with fresh questions on the same material is a better test of what you understand.

Frequently asked questions

How should I practice for a Canvas quiz on my own?

Answer each question before reading the options or the answer key, then read the explanation for every choice you got wrong. Come back to the missed questions the next day to check what you remember.

Does DeckOwl work inside Canvas?

No. DeckOwl is a separate web app you open in your browser, and it does not add buttons or change anything inside Canvas.

What is a good way to study from lecture slides before a quiz?

Turn each slide into a question about its main idea, then test yourself on those questions without the slides open. Explain the answers out loud to confirm you can apply them, not just recognize them.

Which exports are paid?

PDF, DOCX, Anki and CSV exports need Plus, and QTI 2.1 and Moodle XML exports need Pro. The free plan includes studying in the browser only.
