FAQ
Which quiz solver is the most accurate?
QuizAce and Apex Vision AI both claim 95%+ accuracy on multiple choice questions. In our testing, accuracy varies by question complexity, but both consistently outperform general AI tools like ChatGPT for LMS-specific quizzes.
Which quiz solver extension is cheapest?
Quiz Solver AI is the cheapest paid option at $4.90/month for 120 answers. QuizAce offers the best free daily tier (5 questions/day) and weekly pricing ($6.99/week) for exam-week coverage.
Which quiz solver works on the most platforms?
Quiz Solver AI claims 20+ platforms. QuizAce covers the 5 major LMS platforms (Canvas, Blackboard, Brightspace D2L, Google Forms, Moodle) with deep integration including auto-fill and network interception.
Are quiz solver extensions detectable?
Extensions that work in-page (without tab switching) are not detectable by LMS platforms. Canvas, Blackboard, and other LMS systems cannot see your installed Chrome extensions. The risk comes from behavioral patterns like tab switching or finishing too quickly.
