Upload a textbook chapter, lecture notes, or a manual and turn it into study flashcards — questions and answers drawn only from your document. Flip a card to check yourself.
or drop your file here
Drop in a PDF — a textbook chapter, lecture notes, or a manual — and the tool reads the text right in your browser. Pick how many cards you want (5, 10, 15, or 20), then press "Generate cards." You get a grid of question/answer cards; tap any card to flip it and check yourself.
Your PDF file is never uploaded. The text is extracted inside your browser, and only that plain text (plus your card count and language) is sent to our AI service to write the cards. The original file, with its images, layout, and metadata, stays on your device.
Your PDF is a scan or a picture — it has no text layer to read, only an image of the page. Run it through OCR first to add a searchable text layer, then come back and try again. Tip: if the PDF is password-protected, unlock it first with the "Unlock PDF" tool.
The cards are written by AI using only the text from your document — it's told not to use outside knowledge or invent facts. Even so, AI can misread or oversimplify, so give the cards a quick check before you study from them. The tool reminds you of this on the results screen.
Yes. Each run accepts up to about 16,000 characters of text — roughly 12 pages — so feed it one chapter or section at a time rather than a whole book. There's also a fair-use rate limit of about six generations per minute. If you hit either, you'll see a clear message; just shorten the content or wait a minute.
It's free to use — no account or payment needed. Because the cards are written by an AI service, you do need an internet connection: the browser reads your PDF offline, but generating the cards makes a quick call to our server.
