AI Quiz Helper Pricing Compared: Cost per Answer (2026)

For unlimited use, the cheapest AI quiz helper plans we found in October 2026 are Canvas Quiz Solver at $79.99 a year (Canvas only), QuizAce at $89.99 a year and FastSolve at $99 a year. For a single exam week, QuizAce ($6.99) is the cheapest weekly plan. For light users, metered plans such as Apex Vision AI ($7.99 for 500 requests a month) cost less than any unlimited plan. Which is cheapest for you depends on how many answers you actually use, so this guide does the per-answer math.

Last verified: October 12, 2026 against the official documentation linked below.

Every price below comes from the vendor's own pricing page or Chrome Web Store description on October 12, 2026, in US dollars before tax. Where a vendor does not publish a price, we say so instead of estimating. Disclosure: QuizAce publishes this blog and is one of the products compared.

Every plan in one table

Checked on Oct 12, 2026 on each vendor's pricing page (see Sources). "n/a" means the vendor does not sell that billing period.

Two things stand out. First, only three tools sell a week at a time (QuizAce, Canvas Quiz Solver, FastSolve), and only FastSolve sells a semester. Second, about a third of the category does not publish prices at all, which makes a fair comparison impossible until you create an account.

How we built the comparison

We opened each vendor's pricing page and Chrome Web Store description on October 12, 2026 and recorded every plan exactly as shown: price, billing period and usage cap. We did not use prices from third-party review sites, app store trackers or older articles, because those drift quickly in this category. Where a vendor shows a yearly price only as a monthly equivalent, we list both. Where a monthly-billing toggle exists but the page does not display the monthly figure (Quiz Solver AI), we say so rather than infer it.

We also left out accuracy. Vendors in this category quote figures such as "98% accuracy" that cannot be checked from the outside, and a cheaper tool that gets more answers wrong is not cheaper in any useful sense. Test accuracy yourself on a free tier, using a practice quiz in your own subject, before comparing prices.

Cost per answer: the math

Price per month only tells you half the story. A $7.99 plan capped at 500 requests and a $12.99 plan with no cap are cheaper or more expensive depending on your volume. Here is the cost per answer at three realistic monthly volumes:

• 100 answers/month: a few practice quizzes and some homework checks.
• 300 answers/month: regular use across three or four courses.
• 600 answers/month: heavy use, for example a midterm month.

Checked on Oct 12, 2026. Cost per answer = effective monthly price divided by answers used that month. Yearly plans are divided by 12. Quiz Solver AI's 120-answer Quiz Pass ($5.42/mo) is $0.054 per answer at 100 answers but cannot cover 300.

What the numbers show:

• Annual billing dominates. Every yearly plan, metered or unlimited, lands within a few tenths of a cent of the others at 300 answers. If you know you will use a tool through the whole year, the difference between Canvas Quiz Solver, QuizAce, FastSolve and Quiz Solver AI's Quiz Wiz is about $1 a month.
• Metered plans win for light users who pay monthly. At 100 to 500 answers a month, Apex Vision AI's $7.99 Starter beats every unlimited monthly plan, including QuizAce's $12.99. QuizAce monthly only becomes cheaper than Apex once you go past 500 answers and Apex would need its $14.99 tier.
• Canvas-only students have the cheapest unlimited year. If every course is on Canvas, Canvas Quiz Solver's $79.99 beats QuizAce's $89.99 by $10.

Exam week only: weekly plans and top-ups

If you only need help for a burst, compare the cost of one week:

Checked on Oct 12, 2026.

One warning that applies to all weekly plans: they renew every week until cancelled. Left running for a month, QuizAce weekly costs about $30 (4.33 × $6.99), more than twice its monthly plan. Weekly billing is for a defined burst; cancel the day the exams end.

A full semester

For a four-month semester of regular use:

• FastSolve semester: $49 (the only semester plan).
• QuizAce monthly × 4: $51.96.
• Canvas Quiz Solver monthly × 4: $59.96.
• FastSolve monthly × 4: $79.96.
• Apex Vision AI Starter × 4: $31.96, if 500 requests a month is enough.

FastSolve's semester plan is a fair deal for unlimited use and edges out four months of QuizAce. If you will use a tool for two semesters, the yearly plans become cheaper than either: QuizAce yearly ($89.99) is less than two semesters of monthly billing ($103.92).

Choosing a plan in three questions

Most students overpay because they pick a billing period before they know their usage. Three questions sort it out:

1. How many answers will you really use in a month? Spend one normal week on a free tier and count. Multiply by four. Under roughly 100 a month, a free tier or a small metered plan is enough. Between 100 and 500, metered plans (Apex Vision AI Starter) and yearly unlimited plans cost about the same per answer. Above 500, unlimited plans are simpler and usually cheaper.
2. Is your need continuous or in bursts? Continuous use through a semester favours a semester or yearly plan. Bursts around midterms and finals favour a weekly plan bought twice a term: two weeks of QuizAce weekly is $13.98, about the same as one month, and you are not paying for the quiet weeks in between.
3. Will you still use it next term? A yearly plan only pays off if the answer is yes. $89.99 a year is cheaper than seven months of $12.99 monthly billing ($90.93), so the break-even point is about seven months of use. For Canvas Quiz Solver ($79.99 vs $14.99 a month) it is a little over five months; for FastSolve ($99 vs $19.99) about five.

If you cannot answer the third question yet, do not prepay a year. Start with the free tier, move to weekly or monthly, and only switch to annual billing once you know the tool works on your platforms and fits how you study.

Practical ways to spend less

• Line billing up with your calendar. Start a weekly plan the day before the first exam of a cluster, not a week earlier, and set a reminder to cancel.
• Use the free tier for the routine questions. A daily free allowance covers a lot of light homework checking; save the paid period for weeks with several practice quizzes.
• Do not stack tools. Paying for a general tutor and an LMS reader at the same time often doubles the bill for overlapping features. Pick the one that matches where most of your questions are.

Hidden or unclear pricing

Several popular tools do not show a price list before you sign in. AnswerAI's pricing page leads with a free trial offer; Quizard AI's website mentions a "Quizard Pro" subscription without listing its price; SolvelyAI's pricing page did not render prices we could record. CheatMate's pricing page lists Weekly, Monthly and Annual plans but displays each as $0.00, with real checkout behind a login. QuizLLM names its plans (Light at 100 queries per week, Monthly, Semester) but not their prices.

That is not necessarily a bad sign, since in-app pricing can vary by region or promotion, but it does mean you should check three things before entering a card: the renewal period, the usage cap, and the refund policy. Canvas Quiz Solver, for example, publishes a 7-day money-back guarantee, and QuizAce, Canvas Quiz Solver and Answerly AI state that you keep access until the end of the paid period when you cancel.

Taxes, currency and renewals

All prices in this article are in US dollars before tax. Depending on where you live, sales tax or VAT may be added at checkout, and prices may be shown in your local currency at a different rate. Subscriptions billed through a payment processor such as Stripe renew automatically at the end of each period until you cancel, so the first payment is rarely the last. When you compare plans, compare the renewal price and period, not only the first charge, and check whether an introductory discount applies only to the first billing cycle.

What price does not tell you

The cheapest plan is the wrong plan if it does not read your LMS. Before paying, use the free tier on a practice quiz on each platform you use. In particular:

• Platform coverage. Canvas Quiz Solver is Canvas-only. FastSolve lists Schoology, ALEKS and Learnosity. QuizAce covers Canvas, Blackboard Ultra and Original, Brightspace/D2L, Moodle, Google Forms and Microsoft Forms (full list on the platforms page).
• Features per dollar. Apex Vision AI's plans include practice-exam and flashcard generation and a voice tutor, which an LMS reader does not try to offer. If you want a tutor more than a quiz reader, that changes the value equation.
• Track record. AnswerAI (12.4K ratings) and Quizard AI (3K ratings) have far more public reviews than newer tools such as FastSolve, Answerly AI or QuizAce, which is new and has only a few reviews so far.

For unlimited use over a year, Canvas Quiz Solver at $79.99 (Canvas only), then QuizAce at $89.99. For light monthly use, Apex Vision AI's $7.99 Starter plan (500 requests). For one week, QuizAce at $6.99.

How much does QuizAce cost?

Free for 5 questions a day, then $6.99 per week, $12.99 per month or $89.99 per year. Paid plans have no question cap. The yearly plan works out to $7.50 a month, 42% less than paying monthly for twelve months.

Is a weekly plan worth it?

Only for a short, defined period such as finals week. Weekly plans renew automatically, and four weeks cost more than a monthly plan, so cancel as soon as the busy week ends.

Are metered plans (a set number of requests) better than unlimited?

They are cheaper if you stay under the cap. Apex Vision AI's $7.99 plan beats every unlimited monthly plan up to 500 answers a month. Above that, unlimited plans are usually cheaper and you do not have to watch a counter.

Why do some extensions hide their prices?

Some show prices only inside the extension or after sign-up, sometimes because they vary by promotion or region. Before paying, confirm the renewal period, cap and refund policy on the checkout screen.
