Generate the full set

Starts from your own material

Drop in lecture slides, a textbook chapter PDF, typed notes or a photo of a handout. Text is read from images, so you do not have to retype anything.

Spaced repetition built in

Cards come back at the intervals your memory needs, so you spend time on what you are about to forget instead of rereading everything.

Quizzes and mind maps too

Turn the same material into multiple choice, true/false or short answer questions with explanations, or into a mind map of the main ideas.

How it works

Upload your notes or files

Add a PDF, DOCX, PPTX, plain text or image. Paste notes directly if you have them.

Review the generated flashcards

Check the cards, edit anything that needs fixing, and keep the ones that match what your class covered.

Study on a spaced schedule

Study in the browser on the free plan, or export to Anki and CSV on Plus to keep reviewing elsewhere.

DeckOwl reads your files and proposes question and answer pairs for the key terms and ideas. You check them, remove anything off-topic, and then review on a schedule that brings weak cards back sooner.

If you study for a course with a lot of vocabulary, start with one lecture at a time. Smaller sets are easier to edit and easier to finish in a single session.

Frequently asked questions

How many flashcards should I make from one lecture?

There is no fixed number. Aim for one card per distinct term, definition or idea in the lecture, and cut any that repeat the same point.

How do I turn lecture notes into flashcards that help me remember?

Write each card as a question that needs recall, not a sentence to recognize. Keep answers short, and include a why or an example when the concept is easy to confuse with another.

Can I export my flashcards to Anki?

Yes, Anki export is included in the Plus plan at $39/year or $7.99/month. The free plan lets you study in the browser, but exports are not included.

Is there a free plan?

Yes. The free plan includes 3 generations per month and browser study, and no credit card is needed to start. Students get 40% off with a school email.
