Why build your own set instead of looking for a download

If you are hunting for a Quizlet download, you probably want a set of cards you can study from and carry with you. DeckOwl does not offer ready-made sets to download. It builds flashcards from material you already have, such as a PDF of lecture slides, a DOCX of class notes, or a photo of a textbook page.

  • Flashcards generated from your own PDFs, slides, notes or images
  • Spaced repetition that brings back the cards you miss
  • Quizzes with explanations and mind maps from the same upload
  • Free plan to start, with exports to Anki and CSV on Plus
Example biology flashcards (cell and molecular biology)
What is the function of mitochondria?They produce most of the cell's ATP through cellular respiration.
What does the term osmosis describe?The movement of water across a selectively permeable membrane from low solute concentration to high solute concentration.
What is the role of RNA polymerase?It synthesizes RNA from a DNA template during transcription.
What is the difference between mitosis and meiosis?Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically varied haploid gametes.

Flashcards from your material

Upload a PDF, DOCX, PPTX, plain text file or image and get flashcards that match your course, not a generic set someone else wrote.

Spaced repetition

Cards you miss come back sooner, so your review time goes to the material you are still learning.

Quizzes and mind maps too

Build multiple choice, true/false and short answer quizzes with explanations, or map a topic as a mind map from the same upload.

How it works

Upload your material

Add a PDF, slides, notes or a photo of a textbook page. Images are read with text recognition.

Generate your flashcards

The generator turns the content into flashcards. Edit any card that does not match your notes.

Study and review

Study in the browser on the free plan, or export to PDF, DOCX, Anki or CSV on Plus.

Upload a file and the generator returns flashcards with spaced repetition, so cards you miss come back more often. Quizzes with explanations and mind maps are included too. The free plan allows 3 generations per month with study in the browser. Plus costs $99.90/year or $9.99/month and gives unlimited generations plus PDF, DOCX, Anki and CSV export. Students get 40% off with a school email, and no credit card is needed to start.

Because the cards come from your own material, they reflect what your instructor actually covered. Check them against your notes before you study and edit anything that is wrong.

Frequently asked questions

How many flashcards should I make for a biology exam?

For one chapter, 20 to 40 cards is a workable range, and you can add more as new terms come up. Focus on the cards you keep getting wrong rather than rewriting the whole set.

What is the best way to study flashcards?

Review in short sessions and say the answer aloud before you flip the card. Spaced repetition brings back the cards you miss more often, which helps move them into long-term memory.

Can I download my flashcards from DeckOwl?

Free accounts study in the browser without exports. Plus, at $99.90/year or $9.99/month, includes PDF, DOCX, Anki and CSV export.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, which includes 3 generations per month.
