How an AI-powered flashcards app fits into your study routine

Most students already have the material they need in a lecture deck or a chapter PDF. The hard part is turning it into cards you will actually review. An AI-powered flashcards app reads your own files and drafts the question and answer pairs, so you start studying the same day the reading is assigned.

Works from your material

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

Spaced repetition built in

Cards come back at the intervals that help you remember them, so you spend time on what you are about to forget.

Study in the browser

Review cards on any device with a browser. The free plan lets you study without installing anything.

How it works

Upload your material

Add a PDF, slides, notes or photos of pages from your class.

Generate your flashcards

DeckOwl drafts question and answer cards from the text you provided.

Review on a schedule

Study the cards daily and let spaced repetition bring back the ones you miss.

Cards work best when they are reviewed in short sessions over several days. Spaced repetition schedules each card based on how well you recalled it, so easy material appears less often and weak spots come back sooner. You can edit any card that does not match what your instructor emphasized.

If you want to study away from the browser, paid plans export your decks to Anki, CSV, PDF and DOCX. The free plan covers three generations a month, which is enough to test whether the workflow suits how you study.

Frequently asked questions

How many flashcards should I make for cell biology?

Aim for one idea per card, which usually means 40 to 80 cards for a single unit. Group related terms so you can review each topic in one sitting.

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

Review a little every day rather than cramming the night before. Spaced repetition adjusts the gap between reviews based on how well you recall each card.

Can I export my flashcards?

Yes, on the Plus plan you can export to Anki, CSV, PDF and DOCX. The free plan lets you study in the browser but does not include exports.

Is there a free plan?

Yes, the free plan includes 3 generations per month and browser study. Students with a school email get 40 percent off paid plans.
