Create your Cards in a Flash
The best flashcard editor with AI to study and create
Never heard of flashcards?
Relax, a flashcard is worth a thousand words
I have a biology test tomorrow
Create your flashcards. One prompt, one document, a thousand cards
Learn. Play with your created cards.
Drop a PDF, get a deck
PDFs, slides, a photo of your notes, a link or a YouTube video. The AI reads it all for you.
Out comes a ready deck, with several card types and even images.
Don't like one? Edit or delete it and keep studying.
Make cards with one Tab
You type the question. The AI suggests the answer.
Hit Tab and you're done. The tag adds itself.
You stay in control. The AI does the boring part.
Study with your friends
Studying alone is fine. With your crew it's even better.
Create a study group, invite your friends and share the same decks.
One person makes the cards, everyone benefits.

A method backed by science
You're probably thinking: “Woooooow, cool app… but does it actually work?”
It works. Without reviewing, your brain throws away up to 70% of what you studied within days.
Card.AI makes you review at the exact moment you were about to forget — and every review makes the memory stronger.
Already using another method?
Honest comparison.
Where Card.AI wins and where it's not the best choice.
Can't deny it: Anki also uses spaced repetition and is one of the best apps out there. But, Card.AI is easier. Use AI to help you study, create manually, study and review anywhere and anytime with the app and a simple interface.
Frequently Asked Questions
Is Card.AI really free?
Yes. You can create up to 3 decks, and up to 20 flashcards per deck, the study is completely free, and you can use the app on your phone — everything in the Free plan, forever. No tricks.
What materials can the AI turn into flashcards?
PDFs, slides, text, a photo of your notes, a link or a YouTube video. The AI reads the material and builds a ready-to-study deck, with several flashcard types and even images.
Can I create flashcards manually?
Yes. Card.AI has a full flashcard editor for people who prefer to write their own cards. As you type the question, the AI suggests the answer and you accept it with Tab. The card's tag is added automatically, and you can edit or delete any card, including the ones the AI created.
Can I import my Anki decks?
Yes. Import your Anki decks and keep studying in Card.AI without recreating anything. It works the other way too: you can export to Anki.
Can I export my flashcards to other formats?
Absolutely. You can export your flashcards to PDF, CSV, and to Anki. This way, you can use your cards anywhere. Additionally, you can share your decks with friends and study partners all through the platform.
How does synchronization between devices work?
All your decks are stored in the cloud and are automatically synchronized on your phone, tablet, and computer. Just log in to your account and study from anywhere.
Is there a mobile app?
Yes! Card.AI has native apps for iOS and Android, and also works in any browser.
Does it work for any subject?
Yes, but it works BEST for content that memorizes by question-and-answer: laws, formulas, vocabulary, dates, definitions, concepts. For content that requires long open-ended reasoning (essay, written exam), we have the exams mode!
