  • Cards come from your own PDFs, slides, notes and photos
  • Spaced repetition schedules reviews around what you forget
  • Study in the browser on the free plan with 3 generations a month
  • Export to Anki, PDF, DOCX or CSV on Plus

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

Spaced repetition built in

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

Export on paid plans

How it works

Upload your material

Review the generated cards

Check the flashcards DeckOwl creates and edit anything that does not match your course.

Study with spaced repetition

Work through your deck in the browser and let the schedule bring back the cards you miss.

Handmade flashcards take time and often reflect only what seemed important that day. Generating them from your own source keeps the cards tied to your course, and spaced repetition helps you return to the ones you keep missing.

Frequently asked questions

How many flashcards should I study in one session?

Most people learn better from a short, focused set of new cards than from a long deck they skim. Start with the cards from one lecture or chapter and add more once those feel familiar.

How do I study flashcards so they actually stick?

Say the answer out loud or in writing before you flip the card, then rate how well you recalled it honestly. Spaced repetition only works when the ratings match what you really remember.

Can I export my flashcards to Anki?

Yes, but export is a paid feature. Plus is $99.90/year or $9.99/month and includes PDF, DOCX, Anki and CSV export along with unlimited generations.

Do I need a credit card to start?

No. You can start on the free plan with 3 generations per month and study in the browser without adding a payment method.
