The Best Free Quiz Solver Extensions in 2026

QuizSolve is our own extension, so treat this line as disclosure — but the reason it leads for most students is its free tier. You get 5 questions/day + 2 screenshot solves with no signup and no credit card, and it works on the quiz page itself in one to two seconds, no tab switching. It covers Canvas, Blackboard, Moodle, Brightspace, Google Classroom and any LMS quiz page, and handles every common question type with explanations. What it won't do: run inside lockdown or proctoring browsers (no extension can), and it doesn't auto-fill answers into the form the way a couple of paid tools do.

QuizSolverAI is one of the more established paid options, reportedly with 20,000+ users. It's credit-based: you get around 10 free credits per month, then pay roughly $5.99–$24.99/month depending on plan. It supports 20+ platforms and adds features some students want — screenshot solving, a low-profile "Ghost Mode," and step-by-step math. The catch is the free allowance: 10 credits a month runs out fast, so in practice it's a paid tool. If you need its extras and don't mind paying, it's a solid pick; if you want a genuine free daily allowance, it's not the best fit.

CheatMate is a stealth-focused extension with a large review count (11,000+ ratings) and coverage across Canvas, Blackboard, Moodle, D2L and Schoology. Its main drawback for a "free" roundup is that it's paid-first: there's no lasting free tier, only a trial, and the recurring price (around $16/month) is typically shown after you start signup. If you specifically want its stealth positioning and don't mind a subscription, it's capable. But you can't really evaluate it for free the way you can with a true free-tier tool, which is why it ranks lower here for budget-conscious students.

QuizAce is one of the closer comparisons to QuizSolve because it offers a free daily tier alongside paid plans, and it supports Canvas, Blackboard, Brightspace, Google Forms and Moodle. Its headline feature is auto-fill — it can inject answers directly into the form rather than just displaying them, which some students value and others find riskier. If auto-fill is a must-have and you want a free daily allowance, QuizAce is worth a look. Confirm its current daily limit and platform list on its own listing, since free-tier caps on these tools change frequently.

Coursology rounds out the list. It's a paid tool (roughly $8.99–$24.99/month) covering multiple LMS platforms, but it's the hardest to recommend based on public feedback: users have reported slow answers (on the order of 3–4 minutes per question) and billing complaints. Slow responses are a real problem during a timed quiz, where the whole point is speed. It may work fine for untimed homework, but for live quizzes the latency undercuts the value. As always, check recent reviews yourself before subscribing, since service quality can change.
