Turn your own code notes into Quizlet-style flashcards

A class join code opens a set someone else built. DeckOwl builds flashcards from the lectures, labs and slides you already have, and schedules reviews so the syntax sticks.

Why your own code set beats a shared join code

A class join code only opens a set someone else made, which may not match the language, syntax or exam topics in your course. DeckOwl builds Quizlet-style code flashcards from the material you already have, so the cards follow your lectures and assignments.

  • Upload PDF, DOCX, PPTX, notes or photos of pages.
  • Flashcards with spaced repetition for syntax and concepts.
  • Quizzes with explanations to check debugging and logic.
  • Free plan includes 3 generations per month, studied in the browser.

Built from your material

Upload a PDF, DOCX, PPTX, notes or a photo of a page and get code flashcards drawn from it.

Spaced repetition

Cards come back at the intervals where you are most likely to forget them.

Quizzes and mind maps

Multiple choice, true/false and short answer quizzes with explanations, plus mind maps of a unit.

How it works

Add your material

Upload lecture slides, a PDF of course notes, or a photo of a textbook page.

Generate the set

DeckOwl creates flashcards, and you can make a quiz or mind map from the same material.

Study on a schedule

Review in the browser and let spaced repetition bring back the cards you miss.

Upload a Python or Java lab handout and the cards cover the concepts it actually tests. Spaced repetition then schedules reviews so syntax and algorithms stay in memory before the exam.

Frequently asked questions

How many flashcards should I make for an intro programming course?

Start with one card per term, function or rule in each lecture. Then cut the cards you already know well so daily reviews stay short.

How do I study code syntax with flashcards?

Put the error or the expected output on the front and the reason on the back, such as what a line prints or why it raises an exception. Write a few cards by hand, then review them daily instead of cramming.

Can I export code flashcards to Anki?

Yes, but Anki export is a paid feature on the Plus plan at $39 per year or $7.99 per month. The free plan lets you study in the browser with up to 3 generations per month.

Does DeckOwl use Quizlet join codes?

No. DeckOwl creates flashcard sets from the files and notes you upload, so there is no class code to enter. You can start on the free plan without a credit card.
