How many cards does it make?

It depends on the document - a dense chapter can produce a few dozen. The deck is editable, so trim it to what you need.

Can I make cards from a YouTube lecture instead?

Yes. Summarize the video first; the flashcard generator works on any note, including a video transcript.

How to Create Flashcards from a PDF in One Step

Making flashcards by hand is where most study plans stall: an hour of card-writing for twenty minutes of actual recall. An AI flashcard generator does the writing from the PDF you already have; your hour goes to the drilling instead.

Upload the PDF
Drop the file on the Convert PDF & Images to Text page or straight into a new note. Slides, a chapter or a scanned set of notes all work; the OCR reads scanned pages first. Keep it to one topic per upload so the deck stays coherent.

Generate the deck
Open the note's tools and choose Exam Room, then Flashcards. The generator lifts the definitions, named concepts and key facts into question-and-answer cards, using the document's own wording for the answers.
- Definitions become "What is X?" cards
- Processes become ordered-step cards
- Numbers and dates become their own cards - the ones exams love
Prune before you drill
Delete the cards you already know cold and the ones that test trivia; a 40-card deck you finish beats a 200-card deck you abandon. Edit any answer that reads awkwardly - it is your deck.
Drill on the phone
The deck lives in your library on the web and in the app. Drill the cards you keep getting wrong; the ones you get right stop coming back. When a deck is solid, build a practice test from the same note to check it under exam conditions.
