From PDF to study-ready cards

Most students end up with a 40-page PDF from the professor and a test in two days. Learning how to convert a PDF to Quizlet-style flashcards means skipping the manual typing: upload the file, and DeckOwl reads the text and drafts question-and-answer cards you can edit before you study.

  • Upload a PDF, slides, notes or page photos and get draft cards from your own material.
  • Edit or delete any card before you start studying.
  • Review with spaced repetition instead of re-reading the whole chapter.
  • Export to Anki or CSV on Plus, or study in the browser on either plan.
Example cell biology flashcards (high school biology)
Which organelle makes most of the cell's ATP through cellular respiration?The mitochondrion, which uses oxygen and glucose to produce ATP.
What does the cell membrane control?It controls which substances enter and leave the cell, a property called selective permeability.
How do prokaryotic and eukaryotic cells differ?Eukaryotic cells have a membrane-bound nucleus, while prokaryotic cells do not.
What is the main function of ribosomes?They build proteins by translating messenger RNA into a chain of amino acids.

Reads your own files

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

Spaced repetition built in

Cards you miss come back sooner, and cards you know are spaced further apart, so review time goes to what you forget.

Study in the browser

Start on the free plan with 3 generations a month and no credit card. Plus adds unlimited generations and exports.

How it works

Upload your PDF

Add the chapter, lecture deck or handout you need to learn. Scanned pages work too.

Review the generated cards

Check each front and back, trim repeats, and fix anything the source got wrong before studying.

Study on a schedule

Work through cards daily with spaced repetition. On Plus, export to Anki or CSV if you want the deck elsewhere.

DeckOwl also accepts DOCX, PPTX, plain notes and photos of pages. Cards are scheduled with spaced repetition, so the ones you miss come back more often. The free plan includes 3 generations a month with browser study, and Plus adds unlimited generations plus Anki and CSV export.

Frequently asked questions

How many flashcards should I make from one chapter of cell biology?

Aim for one card per distinct term or idea, which often means 20 to 40 cards for a textbook chapter. Cut cards that repeat the same fact and split long definitions into two shorter prompts.

How should I study cell biology flashcards so they stick?

Review in short daily sessions rather than one long cram, and say each answer out loud before you flip the card. Spaced repetition sets the timing, so your job is to rate honestly whether you knew each card.

Can DeckOwl export straight to Quizlet?

No, DeckOwl does not export directly to Quizlet. You can study your cards in the browser, and Plus lets you export to Anki or CSV.

Do I need to pay to try it?

No credit card is needed. The free plan includes 3 generations a month, and Plus is $99.90/year or $9.99/month for unlimited generations and exports, with 40% off for students using a school email.
