Generate the full set

From your own material

Upload PDFs, slides, notes or photos of pages. Text recognition reads the images, so you do not retype anything.

Spaced repetition built in

Cards come back at the intervals that help you remember, so short sessions cover more ground.

Study in the browser

Open your deck on any device and review in a few minutes between classes or before a shift.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text file or image of your notes.

Generate the cards

DeckOwl writes question and answer flashcards from the key terms and ideas in your file.

Review in short sessions

Study the cards and let spaced repetition schedule the ones you miss.

Speed comes from review, not from making cards. Spaced repetition keeps the easy cards from eating your time, so your sessions focus on the material you still miss. Edit the deck when the AI picks a detail you do not need.

The free plan includes 3 generations per month and browser study, so you can test the workflow before paying. Plus adds unlimited generations and exports to Anki, CSV, PDF and DOCX.

Frequently asked questions

How many flashcards should I make for one biology chapter?

Most chapters work well with 20 to 40 cards, covering each key term, process and exception once. Keep cards to one fact each so you can review them quickly.

How often should I review flashcards to remember biology terms?

Review new cards daily for a few days, then let spaced repetition stretch the gaps between reviews. Short daily sessions of 10 to 15 minutes usually beat one long cram session.

Can I export my flashcards to Anki?

Yes, exporting to Anki is included in the Plus plan, which costs $99.90 per year or $9.99 per month. The free plan lets you study in the browser but does not include exports.

Is there a free plan to try it?

Yes, the free plan includes 3 generations per month and browser study. No credit card is needed to start, and students with a school email get 40 percent off Plus.
