How an AI flashcard maker builds your deck

Most students have a stack of slides, PDFs and handwritten notes and no time to turn them into cards by hand. An AI flashcard maker reads your own material and produces question and answer cards you can review in minutes. DeckOwl is a separate tool from Coursebox, and it works from the files you already have.

Generate the full set

Works from your own material

Upload PDFs, DOCX and PPTX files, plain text notes, or photos of pages. Text in images is read with text recognition.

Spaced repetition built in

Cards you miss come back sooner, and cards you know move further apart, so you spend time on what you are likely to forget.

Quizzes and mind maps too

Turn the same material into multiple choice, true/false and short answer questions with explanations, or into a mind map.

How it works

Upload your material

Add a lecture PDF, slide deck, document, pasted notes or a photo of a textbook page.

Generate your flashcards

DeckOwl drafts question and answer cards from the content. Edit or delete any card before you study.

Review on a schedule

Study in the browser each day. Spaced repetition decides which cards come back and when.

Flashcards work best when you see them again at the right time. DeckOwl schedules reviews with spaced repetition, so the cards you struggle with return more often. You can also test yourself with quizzes that include explanations for each answer.

Frequently asked questions

How many flashcards should I make for intro biology?

Start with one card per term or process in a chapter, which often means 20 to 40 cards for a single lecture topic. Cut any card you can answer in a second and add more where you keep missing.

How often should I review flashcards with spaced repetition?

Review missed cards again the next day, then let the gaps grow as you answer correctly. Short daily sessions of 10 to 15 minutes usually work better than one long cram session.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start.

Can I export my flashcards to Anki?

Export to Anki, PDF, DOCX and CSV is included in the Plus plan, which costs $39 per year or $7.99 per month.
