Why a virtual flashcard app works better with your own notes

A virtual flashcard app is most useful when the cards come from the material you are actually tested on. Typing every term by hand takes time, and generic decks often skip the details your instructor covers in class.

Works with PDF, DOCX, PPTX, plain text and images of pages
Cards are reviewed with spaced repetition in the browser
Free plan includes 3 generations per month and no card is needed to start
Plus exports to PDF, DOCX, Anki and CSV for $99.90/year or $9.99/month

Built from your material

Upload PDFs, DOCX and PPTX files, plain notes, or photos of pages. Text recognition reads images so your cards match what you actually studied.

Spaced repetition

Cards you find hard come back more often, and the ones you know well are spaced further apart so review time goes to the right cards.

Study in the browser

Open your deck on a laptop, tablet or phone. The free plan includes browser study, so you can start without installing anything.

How it works

Add your material

Upload a PDF, slide deck, document, text file or photo of a page.

Generate your cards

DeckOwl creates flashcards from the content. Review them and edit any card that needs fixing.

Study on a schedule

Work through your deck in the browser and let spaced repetition decide when each card returns.

Upload your lecture slides, a textbook chapter or a photo of handwritten notes, and DeckOwl turns the key ideas into question and answer cards. You can then review them on any device with a browser, and spaced repetition brings back the cards you keep missing.

Paid plans add export to PDF, DOCX, Anki and CSV, so you can keep your cards in the tool you already use. The free plan gives you 3 generations per month to try it on your own material.

Frequently asked questions

How many flashcards should I make for a biology unit?

Aim for one card per distinct term or concept, so a chapter with 20 key ideas needs about 20 cards. If an answer takes more than a sentence, split it into two cards.

How does spaced repetition help with memorizing biology terms?

It shows cards you struggle with more often and spaces out the ones you know well. Short daily reviews usually stick better than one long session the night before a test.

Can I study my flashcards on my phone?

Yes, you can study in the browser on any device, including the free plan. Exporting your cards to other apps requires a paid plan.

Do I need to pay to export my flashcards?

Yes, exports are included in Plus, which costs $99.90/year or $9.99/month and covers PDF, DOCX, Anki and CSV. The free plan includes 3 generations per month and browser study.
