What the free plan covers and what it does not

A free AI flashcard generator works best when it starts from material you already have, like lecture slides or a textbook chapter. DeckOwl does not need a download. You upload the file in your browser, and the flashcards are built from your own content instead of a generic deck you would have to adapt.

  • Upload PDF, DOCX, PPTX, notes or images
  • Study in the browser on the free plan
  • 3 free generations each month
  • Export to PDF, DOCX, Anki or CSV with Plus

Flashcards with spaced repetition

Cards come back at the intervals you need, so your review time goes to the ones you are about to forget.

Built from your own material

Upload PDF, DOCX, PPTX, plain text notes or photos of pages and get cards based on what you actually need to learn.

Frequently asked questions

Is there a free AI flashcard generator I can download?

DeckOwl does not require a download because it runs in your browser. The free plan gives you 3 generations per month with browser study.

How many flashcards should I make for one lecture?

Aim for one idea per card rather than a fixed count, and split long lectures into sections. Cut any card you cannot answer in a few seconds.

How often should I review flashcards to remember them long term?

Review a card again shortly after you miss it, and let longer gaps build up for the cards you know well. Short sessions done regularly work better than one long cram session.

Can I export my free flashcards to Anki?

Not on the free plan, which is browser study only. Anki, PDF, DOCX and CSV export are included with Plus at $99.90/year or $9.99/month.
