Study with flashcards made from your own material

If you are hunting for a flashcard app on the Play Store, you probably want to study on the go without retyping your notes. DeckOwl takes a different route: you upload the material you already have, and the AI turns it into a deck you can review in the browser.

Works from PDFs, slides, DOCX files, notes and photos of pages
Spaced repetition schedules reviews around what you forget
Free plan includes 3 generations per month and browser study
Plus adds unlimited generations and Anki, CSV, PDF and DOCX export

Example biology flashcards for a study deck

Which organelle produces most of a cell's ATP?The mitochondrion, through cellular respiration.

What is glycolysis?The breakdown of glucose into pyruvate in the cytoplasm, yielding a net gain of 2 ATP.

What does homeostasis mean?Maintaining a stable internal environment despite changes outside the body.

Which molecule carries amino acids to the ribosome during translation?Transfer RNA (tRNA), matched to codons by its anticodon.

How do the outcomes of mitosis and meiosis differ?Mitosis yields two identical diploid cells; meiosis yields four genetically varied haploid cells.

Generate the full set

Your material, not a generic deck

Upload the file you already study from and get cards built from its actual content.

Spaced repetition built in

Cards you struggle with come back more often, so your review time goes where it is needed.

Study in the browser

The free plan lets you review decks without installing anything.

How it works

Upload your file

Add a PDF, slides, DOCX file, plain-text notes or a photo of a page.

Generate flashcards

The AI turns the material into question and answer cards you can edit.

Review on a schedule

Study a few minutes a day and let spaced repetition decide when each card returns.

Upload a PDF, PPTX, DOCX file, plain-text notes or a photo of a page, and the text is read and converted into flashcards. Each card is scheduled with spaced repetition, so the ones you miss come back sooner.

Because the deck comes from your own course material, it reflects what your instructor covers. Plus users can export to Anki, CSV, PDF or DOCX if they want to take the cards into another tool.

Frequently asked questions

How many flashcards should I make for one biology chapter?

Most chapters work well with 20 to 40 cards, each focused on one idea. Start with key terms and definitions, then add cards for processes and comparisons.

Does spaced repetition help with memorizing biology terms?

Yes, spaced repetition shows the cards you find hard more often and the easy ones less often, which supports long-term recall. Short daily reviews work better than one long session the night before an exam.

Do I need to download an app to study with DeckOwl?

No, the free plan lets you study flashcards in your browser. Exports to PDF, DOCX, Anki and CSV are part of Plus, which costs $39/year or $7.99/month.

Is there a free way to start, and do I need a credit card?

You can start on the free plan with 3 generations per month and no credit card. Students get 40% off with a school email.
