This free AI flashcard generator turns a PDF, a YouTube video, or your own notes into question-and-answer cards in seconds. Each card tests one fact, so you study the ideas, not the formatting. Practice them on the page in five modes, edit any card, and export to CSV, Anki, or Quizlet for free. Sign up free to save the cards and drill them with real spaced repetition.
Give it your source
Paste your notes, a transcript, or an article, paste a YouTube link, upload a PDF, upload a .pptx deck, upload a photo of the page, or paste a link to a public web page. No account needed.
Run the tool
The AI reads your source on our server and writes the result. A long file takes a little longer.
Study or save
Use it right away, or save it to a free library and get the full study kit from the same source.
Why use this flashcard generator
From any source
A textbook PDF, a lecture on YouTube, or notes you paste. One generator handles all three.
Practice right here
Five study modes on the page: flip through the deck, Learn with multiple choice, Write the answers, Match against the clock, or take a graded Test.
Edit before you export
Fix a card, add one, swap fronts and backs. Then export to CSV, Anki or Quizlet, Markdown, JSON, or print.
Real spaced repetition
Study the cards with a real SM-2 schedule, so they come back right before you'd forget.
Who it's for
Students
Turn a chapter or a lecture into a deck before the exam, instead of writing every card by hand.
Teachers
Build a card set for a class from the reading, then share or export it.
Language learners
Make sentence cards from real audio you transcribed, with the word in context.
Questions
How does the flashcard generator work?
Paste a YouTube link, upload a PDF, or paste text. The AI reads it and writes the most useful question-and-answer cards, each testing one fact.
Is it really free?
Yes. Run it without an account, practice the cards in five modes right on the page, and export them to CSV, Anki, or Quizlet. Make a free account to save the cards and drill them with real spaced repetition.
Can I study the flashcards without downloading them?
Yes. Every set opens with study modes built in: flip through the deck and sort cards into known and still learning, Learn with multiple choice, Write the answer from memory, Match pairs against a timer, or take a graded Test. You can also edit or add cards first.
Can it make flashcards from a YouTube video?
Yes, as long as the video has captions. Paste the link and it reads the captions, no watching required.
