How PDF to flashcards works

1

Upload your PDF

Drop in a lecture deck, a textbook chapter, or any study PDF (text-layer PDFs work best).

2

Brainfy reads the document

The text layer is extracted, then the AI proposes question / answer pairs grounded in the actual content of your PDF.

3

Review and save the deck

Keep the cards that matter, edit the wording, throw out the rest. The kept cards enter spaced repetition immediately.

Why use Brainfy for PDF flashcards

Who this is for

Built for students staring at a 60-page lecture PDF the week before exams. Med students, law students, engineering students, anyone with dense reading and a deadline. Drop the PDF in, get a deck out, start reviewing tonight.

Frequently asked questions

Is the PDF to flashcards tool free?

Yes. Brainfy is free during beta — upload as many PDFs and generate as many decks as you want.

Can I upload scanned PDFs?

Brainfy uses the PDF's text layer for fastest, most accurate flashcard generation. If your PDF is a scan, run it through OCR first or use Brainfy's image import for individual pages.

How large a PDF can I upload?

Up to 1 GB — full textbook chapters, lecture decks, and exam papers all work. Larger files take longer to process.

Does Brainfy store my PDF?

Your PDF and generated cards live in your Brainfy library so you can return to them later. See the privacy policy for full data handling.

Can I edit the generated cards?

Yes — every card is editable. The AI drafts; you ship. Keep, tweak, or delete each card before it enters spaced repetition.
