Why use this flashcard generator

From any source

A textbook PDF, a lecture on YouTube, or notes you paste. One generator handles all three.

One fact per card

The AI writes tight question-and-answer cards. No bloated cards you skip on review day.

Export to Anki or CSV

Take the cards with you. Export the whole set to CSV or straight into Anki, free, no account.

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.
