It accepts PDFs, PowerPoints, Word files, web links, videos, images, text and audio, and can generate multiple-choice, fill-in-the-blank, true/false, open-ended, calculation, matching and mixed questions. Learning features include concept-level performance feedback, personalized study plans, AI explanations, spaced-repetition reviews and daily practice sessions. Users can add course materials to a Notebook and chat with an AI assistant described as trained on those materials. Quizzes and answer keys can be exported to Word, PDF, Google Classroom, Moodle, Canvas, Blackboard, Kahoot and Aiken. The site describes Quizbot as serving teachers, schools, companies, students, organizations and tutors.

Quizbot says uploaded files are removed after questions are successfully created; its privacy policy describes encryption in transit and account-deletion retention terms.

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.
