Quizlet

Turn your course materials into AI flashcards, quizzes, and a tutor.

A study platform that ingests a student's own materials — PDFs, slides, notes, audio, and video — and turns them into flashcards, quizzes, and summaries. Its Spark.E tutor is trained on those uploads to answer questions, generate practice tests, and explain concepts over chat or voice. A free tier offers limited chats and uploads, with paid tiers unlocking unlimited use and a live lecture assistant.
