Turn anything into flashcards.
Upload a photo of your notes, a PDF, or paste your notes or a video transcript. Cardstock reads it and builds a full study kit: summary, flashcards, quiz, and more.
Three steps, no busywork
The part that used to take an hour of re-reading and rewriting now takes about the time it takes to make coffee.
Feed it something
A photo of handwritten notes, a textbook page, a lecture PDF, or a pasted transcript.
It reads and sorts
Cardstock pulls out the ideas worth remembering: summary, key concepts, definitions, and facts.
You study
Flip through flashcards, take a quiz, and answer short questions — all generated for you.
A full study kit, not just a summary
