rayQuiz FAQ: AI quizzes, online exams, pricing

rayQuiz is a Vietnamese online education platform by RayLabs: AI quiz generation, secure online exam rooms with anti-cheat, auto-grading with explanations, class/organization management, and a quiz marketplace. Students use it completely free.

Students take quizzes and practice on rayQuiz for free, with no limits. Teachers get a free tier with core features; paid plans (from 129,000 VND/month) unlock advanced AI authoring, the marketplace and organization management — see the Pricing page.

Kahoot! and Quizizz (Wayground) focus on classroom games and playful review. rayQuiz is built for formal assessment: difficulty-tiered blueprints, dedicated anti-cheat exam rooms, Word export, marketplaces and center/school management. rayQuiz still keeps points, streaks and leaderboards for a competitive vibe.

Three steps: (1) upload a PDF/Word file or paste your outline, (2) pick the question count, types and difficulty mix, (3) the AI drafts a complete quiz with answers and explanations in about 30 seconds for you to review, edit, then export to Word or assign.

PDF, Word (DOCX), or pasted text such as outlines and lecture notes. Well-structured documents — clear headings and key points — produce the most accurate quizzes.

The AI drafts questions grounded in your source material, with answers and explanations included. rayQuiz’s rule: the teacher always reviews before students see the quiz — AI saves the time, the teacher keeps the quality.
