Laxu AI is a study app for students. It turns the material students already have, lecture PDFs, photographs of handwritten notes, slide decks and recordings of classes, into flashcards, structured study notes, practice quizzes and podcast episodes. Founded in 2024, it runs on web, iOS and Android. It is built around spaced repetition, and exports to Anki and PDF so students keep their own work whether or not they stay subscribed.
