StudyGlen is the best free AI quiz generator for most users. It's the only tool that accepts PDF, text, and image input (with OCR), generates multiple choice, true/false, and short answer questions with AI-powered explanations, and supports 37 languages — all with a free guest tier that requires no account. Quizgecko is a strong paid alternative with polished UI, and Quizizz excels for gamified classroom use. For pure PDF extraction, NoteGPT is competitive but lacks multilingual support.
