Why study from your own cards

Many students who already use Knowt want the same kind of study cards built from their own class material, not a generic set. Upload a PDF, DOCX, PPTX, a notes file or a photo of a page, and DeckOwl turns it into Knowt-style flashcards with spaced repetition scheduled for you.

  • Every card comes from the material you actually have to learn.
  • Spaced repetition sets review timing based on how well you recall each card.
  • Free plan: 3 generations per month, study in the browser.
  • Plus: unlimited generations with PDF, DOCX, Anki and CSV export, at $39/year or $7.99/month.

Built from your material

Upload PDF, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition.

Spaced repetition included

Cards come back at the right time so you review what you are about to forget, not everything at once.

Quizzes and mind maps too

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

How it works

Upload your source

Drop in a PDF, slide deck, notes file or a photo of a page. No credit card is needed to start.

Review the cards

Check the generated flashcards, edit any that are unclear, and remove the ones you do not need.

Study on a schedule

Work through the deck in the browser. Spaced repetition brings back the cards you miss more often.

Good cards test one idea each. Write the question on the front, keep the answer short on the back, and review the cards you miss more often than the ones you already know. The scheduling handles itself, so your time goes to recall instead of sorting.

Frequently asked questions

How many flashcards should I make for one chapter?

Aim for one card per key term or idea, which often means 20 to 40 for a typical chapter. If a card tests two facts at once, split it into two cards.

Is spaced repetition better than rereading my notes?

Spaced repetition schedules reviews close to the point you would forget, which usually works better for long-term recall than rereading. Try to answer from memory first, then check the back of the card.

Can I export my flashcards to Anki or PDF?

Yes, but exports are a paid feature: Plus includes PDF, DOCX, Anki and CSV export. The Free plan lets you study in the browser without exports.

Do I need a credit card to try it?

No. You can start on the Free plan with 3 generations per month without adding a credit card.
