Why a custom deck beats a downloaded one

A pre-made Anki deck can cover the wrong chapter, skip your professor's emphasis or use terms your course does not. Building one by hand takes hours that most students would rather spend studying.

  • Cards are written from your own PDFs, slides, notes and images.
  • Each card asks one question so you can tell exactly what you missed.
  • Spaced repetition spaces reviews by how well you recall each card.
  • Anki export is available on Plus; no credit card is needed to start.
Example spaced repetition flashcards for an Anki deck
What does spaced repetition schedule?Reviews at increasing intervals, so each card returns shortly before you would otherwise forget it.
Why do active recall cards beat rereading?Pulling an answer from memory strengthens retrieval, while rereading mostly creates a feeling of familiarity.
What is the testing effect?Retrieving information strengthens later recall more than restudying the same material for the same amount of time.
Should one flashcard hold one fact?Yes, because single-fact cards are easier to grade honestly and show exactly which part you missed.
What is a cloze deletion card?A sentence with one key term hidden, such as 'Mitochondria produce most of the cell's ATP', shown as a blank to fill in.

Spaced repetition included

Cards come back at increasing intervals, so you review each one shortly before you would forget it.

Export to Anki on Plus

Plus exports your cards to Anki, along with PDF, DOCX and CSV. The free plan keeps everything in the browser.

How it works

Upload your material

Add a PDF, slide deck, set of notes or a photo of a textbook page. Text recognition reads images.

Generate your cards

DeckOwl turns the content into flashcards, and you can also create quizzes and mind maps from the same source.

Study or export

Review in the browser with spaced repetition, or export to Anki on the Plus plan once the deck is ready.

DeckOwl reads your own files and writes flashcards with a front and a back, so the deck reflects what you actually need to learn. You can then schedule reviews with spaced repetition and keep adding cards as the course moves on.

Free accounts get 3 generations per month and browser study. Plus, at $39/year or $7.99/month, adds unlimited generations and Anki export, and students with a school email get 40% off.

Frequently asked questions

How many flashcards should I make for a single exam topic?

Most students do better with a focused set of cards for each lecture or chapter than one huge deck. Start with the key terms, definitions and facts your instructor emphasized, then add more as you spot gaps.

Does spaced repetition really help with long-term memory?

Spacing reviews over time generally produces better long-term recall than cramming the same material in one sitting. The schedule works best when you rate your recall honestly on each card.

Can I export my deck to Anki?

Anki export is a Plus feature, available at $39/year or $7.99/month, and Pro adds Moodle XML and QTI 2.1 export. The free plan lets you study cards in the browser without exports.

Is there a free way to try it first?

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