Best Free Quiz Solver Extensions That Actually Work (2026)

Searching for a free quiz solver extension that actually works without forcing you to enter a credit card? You're not alone. Dozens of Chrome extensions promise free AI-powered quiz answers, but most of them hit you with a paywall after one or two uses. We installed and tested every major quiz solver extension in 2026 to find out which ones give you a genuinely usable free tier — and which ones are just bait-and-switch.

Here are the five extensions that actually deliver free quiz-solving capability, ranked by how useful their free tier really is for everyday student life.

What Makes a Quiz Solver "Actually Free"?

Before we get into the list, let's define what "actually free" means. A lot of extensions use the word "free" loosely. Some give you a one-time handful of credits that run out during your first quiz. Others offer a 3-day trial that silently charges your card on day four. That's not free — that's a trap.

For this ranking, we evaluated each extension on three criteria:

1. Renewable free allowance — Does the free tier reset daily or weekly, or is it a one-time credit dump? A real free tier means you can keep using it indefinitely without paying.
2. No credit card required — If you have to enter payment info to "start your free trial," it doesn't count. You should be able to install and start solving immediately.
3. Functional on actual quizzes — Some free tiers are technically available but so limited they're unusable on a real 20-question exam. We tested each one on live Canvas, Blackboard, and Google Forms quizzes.

1. QuizAce — Best Free Tier for Daily Use (Our Pick)

QuizAce offers 5 free questions per day, every day, with no credit card required. Install the extension, create a free account, and you're solving quizzes immediately. The daily allowance resets at midnight, so you always have questions available when you need them.

What sets QuizAce apart from every other free option is the combination of platform coverage and features. It works on Canvas (Classic and New Quizzes), Blackboard Ultra, Brightspace D2L, Google Forms, and Moodle — all five major LMS platforms. No other free extension covers all of them. It also includes auto-fill (answers are selected for you automatically), image recognition for diagram and chart questions, and confidence scores so you know how certain the AI is about each answer.

The Chrome Web Store rating sits at 5.0 out of 5, which reflects how reliably it works across platforms. Activation is a single keyboard shortcut (Cmd+Shift+X on Mac, Ctrl+Shift+X on Windows) — no clicking through menus during a timed exam.

If you need more than 5 questions per day, paid plans start at $6.99/week (great for exam week) or $12.99/month for unlimited questions. The yearly plan at $89.99/year works out to $7.50/month — a 42% savings.

Why it's #1: Most generous daily free tier with full platform support, auto-fill, and image handling. No other extension gives you this much functionality at zero cost.

2. Apex Vision AI — Most Generous Free Tier

Apex Vision AI offers 30 free requests per day, which is the highest raw number on this list. If sheer volume of free answers is what you care about, this is the one to look at. The extension supports Canvas, Blackboard, and Moodle, and includes six different input methods including a screenshot solver for when the extension can't read the page directly.

The Chrome Web Store rating is 4.9 out of 5 with over 1,600 ratings, indicating a large and generally satisfied user base.

The trade-off? Apex Vision does not support Brightspace D2L, which is a dealbreaker if your university runs on that platform. It also lacks auto-fill — you get the answer, but you have to select it yourself. On a timed 50-question exam, that manual step adds up. Paid plans range from $7.99 to $19.99 per month depending on the tier.

Best for: Students on Canvas or Blackboard who want maximum free questions per day and don't mind selecting answers manually.

3. Quiz Solver AI — One-Time Free Credits

Quiz Solver AI gives new users 10 free credits when they sign up. That sounds reasonable until you realize those 10 credits are not daily — they're total. Once you use them, they're gone forever unless you pay. A single quiz with 20 multiple-choice questions will burn through your free credits before you're halfway done.

That said, Quiz Solver AI has the widest platform support of any extension on this list, claiming 20+ platforms including a Firefox version. If you're on a niche LMS that other extensions don't cover, it might be worth the 10-credit test drive.

The Chrome Web Store rating is 3.9 out of 5 with 73 ratings — noticeably lower than the competition. The cheapest paid plan is $4.90/month, making it the most affordable paid option if you do decide to upgrade.

Best for: Testing whether a quiz solver works on your specific platform before committing to a paid plan elsewhere. Not a viable long-term free option.

4. AnswerAI — Free Homework Helper

AnswerAI is the most popular extension in this category by sheer install numbers — 100,000+ users and a 4.9 out of 5 rating with over 12,000 reviews on the Chrome Web Store. It offers a limited free tier across multiple platforms.

Here's the catch: AnswerAI is primarily a homework helper, not a dedicated quiz solver. It excels at helping you understand problems, work through solutions, and learn concepts — which is great for take-home assignments. But for in-page, timed quiz solving where you need answers injected directly into your LMS, it falls short. There's no auto-fill, no keyboard shortcut activation, and the workflow requires more manual interaction than purpose-built quiz solvers.

If your definition of "quiz solver" includes homework and take-home assignments, AnswerAI is a strong contender. If you need something that works mid-exam on a ticking clock, look elsewhere.

Best for: Homework assignments, take-home tests, and students who want to understand the material rather than just get answers during a timed quiz.

5. QuestionAI — Free General AI Assistant

QuestionAI has 100,000+ users and a 4.8 out of 5 rating with over 2,000 reviews. It offers free access with usage limits across multiple platforms. Like AnswerAI, it's more of a general-purpose AI assistant than a dedicated quiz-solving tool.

The extension works by having you take screenshots or manually paste questions — it doesn't automatically detect quiz questions on the page. For a 10-question untimed practice quiz, that workflow is fine. For a 50-question midterm with a 60-minute timer, the manual input process makes it impractical as your primary quiz solver.

QuestionAI is best understood as a general homework AI that happens to be available as a Chrome extension, rather than a quiz-specific tool built for in-page LMS integration.

Best for: General homework help and study assistance, not timed in-page quiz solving.

Extensions to Avoid (Hidden Costs)

During our testing, we found several extensions that advertise "free" but don't deliver. Save yourself the time:

• CheatMate — Claims to be free but the pricing page shows $0.00 in a way that appears broken. You have to create an account just to discover the real pricing structure, which is never a good sign.
• CanvasSolver — Advertises a "$0.99 promo" price but doesn't disclose what the normal pricing is. It's also Canvas-only, which limits its usefulness. If the pricing isn't transparent up front, expect surprises.
• Various "3-day trial" extensions — Multiple extensions in the Chrome Web Store offer a "free trial" that requires your credit card upfront and auto-charges after 3 days. If you forget to cancel (and they're counting on you forgetting), you're on the hook for a monthly subscription. Always check the fine print before entering payment info.

Our Verdict

The best free quiz solver extension depends on what you need it for:

• For timed quizzes with auto-fill: QuizAce — 5 free questions per day with automatic answer selection, image support, and all five major platforms. The only free option that fills in answers for you.
• For maximum free questions per day: Apex Vision AI — 30 free requests daily is hard to beat on volume alone, though you lose auto-fill and Brightspace support.
• For homework help (not timed quizzes): AnswerAI — The most popular extension by install count, great for assignments where you have time to work through problems.

For most students taking timed quizzes on Canvas, Blackboard, or any other LMS, we recommend starting with QuizAce's free tier. Five questions per day is enough to test it on your actual quizzes and see the results for yourself. If you need unlimited questions during exam season, check out the paid plans starting at $6.99/week.

No credit card, no trial period, no bait-and-switch. Install it, create a free account, and solve your first quiz in under a minute.
