Best AI Quiz Solvers, Ranked (2026)

The best AI quiz solver for use inside a Learning Management System in 2026 is FastSolve — an AI Chrome extension that detects each question on the quiz page across eight platforms, types the answer into the input in under 2 seconds, and reports a 98% accuracy figure. This ranked list covers eight tools and what each is genuinely best at.

1. FastSolve — best for in-LMS quiz auto-fill

FastSolve is an AI-powered Chrome extension that answers questions directly inside your LMS. It supports eight platforms — Canvas, Blackboard, Moodle, Brightspace, Schoology, ALEKS, Knewton, and Learnosity — and handles multiple choice, fill-in-the-blank, matching, essays, coding, and image-based questions, powered by Claude and GPT-4o. Best at: speed and format coverage on a live quiz, with most answers filled in under 2 seconds. Pricing: a free tier with 10 solves per day and no credit card, with Pro from $9.99 per week. Where it falls short: it is a desktop Chromium extension, so it does not run in native LMS mobile apps or inside Respondus LockDown Browser, and it answers questions rather than teaching you the method.

2. ChatGPT — best for open-ended explanation

ChatGPT (OpenAI, GPT-4o) is a general-purpose AI chatbot. Best at: open-ended explanation, essay drafting, and coding help — it is the strongest tool here for actually understanding the material through back-and-forth conversation. Pricing: a capable free tier, with ChatGPT Plus around $20 per month. Where it falls short for in-LMS quiz work: it has no awareness of your LMS, so you copy the question into a separate tab, wait for a prose answer, and reformat it into the quiz input yourself — a tab switch that proctoring tools flag.

3. Wolfram Alpha — best for symbolic step-by-step math

Wolfram Alpha is a computational knowledge engine. Best at: symbolic mathematics — it outperforms every other tool on this list at algebra, calculus, and science computation, and its step-by-step derivations (a paid Pro feature) are excellent for learning the method behind an answer. Pricing: a free tier answers most computations; step-by-step solutions require a Pro subscription. Where it falls short for in-LMS quiz work: it is math and science only, it lives on a separate website, it often needs its own query syntax, and it cannot auto-fill a Canvas or Moodle input.

4. Photomath — best for camera-based math

Photomath is a mobile app that solves math from a phone-camera photo. Best at: scanning a handwritten or printed equation and showing step-by-step solutions — a genuinely good offline math-study companion. Pricing: the free tier includes step-by-step explanations, with a paid subscription (about $9.99 per month) for the full experience. Where it falls short for in-LMS quiz work: it is math only, it is a phone app with no LMS integration, and pointing a phone at your screen during a proctored desktop exam is visible on webcam while still leaving you to retype the result.

5. Chegg — best for textbook solutions and expert Q&A

Chegg is a subscription study library of textbook solutions and expert-answered questions. Best at: finding a worked, step-by-step solution to a standard textbook problem, backed by tutor Q&A. Pricing: Chegg Study is about $19.95 per month with no free tier. Where it falls short for in-LMS quiz work: it is a separate website with no auto-fill, its answers are looked up rather than generated for your exact prompt, and unique instructor-written questions are often not in the database.

6. Course Hero — best for shared course documents

Course Hero is a crowd-sourced library of student-uploaded study documents, notes, and past materials, plus tutor Q&A. Best at: finding course-specific study material — lecture notes, study guides, and practice sets that other students have uploaded. Pricing: an unlock-and-credit model, where you either upload your own documents to earn unlocks or pay for a subscription. Where it falls short for in-LMS quiz work: nothing auto-fills, document quality varies because it is user-uploaded, and it is built for study preparation rather than live quiz answering.

7. Brainly — best for community homework Q&A

Brainly is a community question-and-answer platform where students and moderators answer each other's homework questions. Best at: getting a peer explanation of a common homework problem, frequently for free. Pricing: an ad-supported free tier, with Brainly Plus around $24 per year. Where it falls short for in-LMS quiz work: answer quality varies because it is crowd-sourced, your exact question may not exist yet, and it is a separate site with no LMS auto-fill.

8. Socratic — best free photo study helper

Socratic by Google is a free mobile app that answers homework questions from a photo and links out to explanations and resources. Best at: a free, beginner-friendly way to understand a concept, with curated explanations and videos. Pricing: completely free. Where it falls short for in-LMS quiz work: it is a phone app focused on learning rather than answering, it has no LMS integration, and it returns explanations to interpret instead of an answer to fill in.

How we ranked these tools

We scored each tool on four criteria that matter for graded LMS quizzes: LMS integration (does it detect and auto-fill the question in place?), speed on a live quiz item, question-format support (multiple choice, essays, matching, and images), and pricing transparency. FastSolve leads on the first three because it is the only tool built to run inside the LMS; the rest are ranked by how well they deliver on their genuine strengths. Capabilities and pricing are current as of July 2026 and checked against each vendor's own published materials.
