Making an AI flashcard deck from your own course material

What is the main function of ribosomes?Protein synthesis, translating mRNA into polypeptide chains.
What does the phospholipid bilayer of the cell membrane do?It forms a selectively permeable barrier between the cell's interior and its environment.

Built from your material

Start with the files you already have, including PDF, DOCX, PPTX, plain text notes and images. Photos of pages are read with text recognition.

Spaced repetition

Cards come back at intervals based on how well you recall them, so you spend time on the ideas you are about to forget.

Export when you need it

Plus users can export to PDF, DOCX, Anki and CSV. Free users can study in the browser.

How it works

Upload your source

Add a PDF, slides, notes or a photo of a page. You can start on the free plan with 3 generations per month.

Review the cards

Check the generated flashcards, edit anything that is unclear, and keep the ones that matter for your exam.

Study on a schedule

Work through the deck with spaced repetition so each card returns right before you would forget it.

Good flashcards have one idea per card, a clear question on the front and a short answer on the back. Review them in spaced intervals, rate each card honestly, and say the answer aloud before you flip it. That combination builds recall, which is what exams measure.

If you later need the deck somewhere else, Plus lets you export to Anki or CSV, so your cards stay portable.

Frequently asked questions

How many flashcards should I make for a biology unit?

Aim for one card per key term or concept, so a typical chapter might yield 20 to 40 cards. Focus on ideas you cannot yet recall rather than copying every sentence from the text.

What is the best way to study flashcards?

Review cards in spaced intervals and rate each one honestly so harder cards return sooner. Answer out loud before you check the back, since recalling an answer works better than recognizing it.

Can I export my flashcards to Anki?

Yes, Anki export is included in the Plus plan, which costs $39/year or $7.99/month. The free plan lets you study in the browser with 3 generations per month but does not include exports.

Does DeckOwl work with photos of pages?

Yes, images such as photos of pages are read with text recognition, alongside PDF, DOCX, PPTX and plain text notes. No credit card is needed to start.
