Quizcard

Quizcard turns the material you already have — a PDF chapter, a Word doc of notes, a lecture's slides — into a flashcard deck grouped by topic, with the charts and diagrams kept on the cards. Built-in PDF reader with highlights, a tutor that answers from your own pages, search across everything, offline study, and public deck pages you can share with a link. Making and studying your own cards is free; your first two generated documents are free too.
