AutoQuiz.AI vs PDFQuiz

AutoQuiz.AI is a web service that turns uploaded educational documents into quizzes for educators and students. It accepts PDF, Word, PowerPoint and plain-text materials, then generates single-choice, multiple-choice, short-answer and true/false questions with answer keys and explanations. Educators can adjust difficulty, cognitive depth and special requirements, edit questions, and share them as self-paced homework with due dates or live sessions joined by QR code. Quizzes can also be exported as PDFs with or without answer keys. The service grades objective and short-answer responses, explains wrong answers and provides class insights. Students get a missed-question review queue, topic mastery tracking and progress analytics. The Free plan costs nothing and includes 3 AI quiz generation credits, up to 10 saved quizzes, homework assignments and live quiz sessions. Uploaded content may be processed by Google or OpenAI; the terms warn that AI output can be inaccurate.

PDFQuiz uses AI to turn PDFs and other uploaded documents into interactive quizzes. Its listed 16 upload formats include office documents, images, and text formats; six question types range from single choice and matching to open ended. OCR can read scanned pages and photos. Users can take quizzes online, study questions as flashcards, download quizzes and results as PDFs, and export quizzes to Anki depending on plan. Paid plans can generate quizzes in a chosen output language from a list of more than 180. The free options allow a 10-question quiz without an account, or three quizzes of up to 10 questions each for a free account; account quizzes can use documents of up to 20 pages. Paid tiers add differing character limits and features such as invitation links, timers, editing, API access, and Zapier integration. The Elite plan lists up to 1,500 quiz invitations per month, API access, and Zapier integration. Uploaded files, quizzes, and results are retained while an account exists, though users can request deletion. The listed starting price is $5/mo (annual).
