PDFQuiz vs Quizzen

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).

Quizzen uses AI to turn documents into quizzes, exams, and assessments. It accepts PDF, Word (.docx), and PowerPoint (.pptx) files, and says scanned PDFs can be processed with OCR. Users choose question counts and difficulty, generating multiple-choice, true/false, or fill-in-the-blank items that can be reviewed and edited before export. PDF and CSV exports are available to all users; paid plans add Moodle XML, Kahoot, and Wooclap formats. Enterprise users can send text to /api/v1/generate and receive structured JSON questions. Uploaded documents are automatically deleted after processing, while the terms say users retain ownership of source documents and generated quizzes. Student features include practice sets, progress tracking, mobile-optimized quizzes, and retakes. The Free plan costs nothing and allows three quizzes every 30 days, up to 10 questions each, with PDFs up to 20 pages. Standard Quiz costs $0.99, paid once; Premium Quiz costs $1.49, paid once. Pro costs $3.99 a month, billed annually at 39.90 USD. Enterprise costs $29 a month, billed annually at 290 USD.
