When their own FAQ admits it's "for exams without a proctoring tool."
Canvas Quiz Solver (canvasquiz.com) injects a visible button onto every Canvas question and writes the answer directly below the question in the page HTML. Because of that, their own website admits it cannot be used on proctored exams—and it only works on Canvas while billing $48.99 every 4 months ($146.97/yr).
"...click the button on a question, and the answer appears right below it, on Classic and New Quizzes. It does not run inside LockDown Browser, and proctoring tools such as Honorlock and Proctorio can turn Chrome extensions off, so it is for exams without a proctoring tool."
ExamGhost never injects visible "Get Answer" buttons or text blocks underneath Canvas questions. Double-click any question to auto-fill or highlight inside a closed Shadow DOM with 4-Layer Focus Shield.

Writes Answers & Buttons Directly Under Every Question
CanvasQuiz states on its homepage: "open your Canvas quiz, and click the button on any question. The answer appears right below the question."
- Visible to Anyone Walking By: Pushes Canvas questions down the page to display a third-party answer box right inside the quiz form.
- Trivial
MutationObserverDetection: Appending child nodes inside#questionsimmediately alerts page-integrity scripts.
Double-Click Solve + 3 Stealth Delivery Modes
ExamGhost never inserts a single button or answer paragraph into Canvas's HTML document tree:
- Invisible Auto-Fill Mode: Double-click any question and ExamGhost silently selects the correct radio button in 0.3s with zero on-screen UI.
- Closed Shadow DOM + Panic Key (
⌘+Shift+U): Need step-by-step explanations? Render them at 20% Ghost opacity inside an isolated Shadow root and flush memory in <8ms.
"BUILT FOR CANVAS. ONLY CANVAS."
Even if your university uses Canvas as its main portal, STEM and business professors constantly assign quizzes on external publisher platforms or secondary LMSs. CanvasQuiz does nothing on:
One Extension for Every Portal You Use All Degree
ExamGhost works natively across all 20+ university LMSs and locked publisher iframes—plus ⌘+Shift+S Snap-It Vision crops any diagram on any website:
Because it renews every 4 months instead of once a year, keeping CanvasQuiz across a 4-year degree costs $587.88—including summer months when you aren't in class.
Still restricted to Canvas LMS only, with zero window-blur Focus Shield and visible DOM button injection.

Backend & DOM Behavior: Routes checkout and API requests via AWS Lambda Function URL 7xv2cav7t3iceljjbwjn4akknm0kymha.lambda-url.us-east-1.on.aws and mutates the host Canvas quiz DOM by appending button and answer nodes directly beneath question containers.
"Our professor switched our biology midterms to proctored Canvas quizzes, and my chemistry lab ran on Blackboard. I read CanvasQuiz's own FAQ admitting it is only for exams without a proctoring tool and only works on Canvas, plus it wanted $48.99 every 4 months. I tested ExamGhost's 50 Free Solves and upgraded to the $99/year pass—it works on both Canvas and Blackboard inside a closed Shadow DOM with zero flags."
Frequently Asked Questions
Everything you need to know about CanvasQuiz (v3.9.0) vs ExamGhost.
Does CanvasQuiz (Canvas Quiz Solver) work with Honorlock or Proctorio?
No. CanvasQuiz (eiceeladfkklbbdlgpfhgclfhlmkpmjb v3.9.0) explicitly concedes in its official FAQ on canvasquiz.com: 'It does not run inside LockDown Browser, and proctoring tools such as Honorlock and Proctorio can turn Chrome extensions off, so it is for exams without a proctoring tool.' In contrast, ExamGhost operates in a closed Shadow DOM container and intercepts events natively, remaining 100% invisible.
Why does CanvasQuiz inject visible buttons and answers under questions?
CanvasQuiz states on canvasquiz.com: 'open your Canvas quiz, and click the button on any question. The answer appears right below the question.' Appending physical DOM buttons labeled 'Get Answer' and writing answer blocks directly below question nodes in the host HTML makes it trivial for MutationObserver scripts and quiz integrity filters to detect the extension.
How does ExamGhost solve questions without modifying the DOM?
ExamGhost uses an isolated closed Shadow DOM (#shadow-root) rendered within a private host container. It does not insert a single button or answer node into Canvas's document tree. Furthermore, ExamGhost offers Invisible Auto-Fill, Smart Highlight, and Snap-It in-memory screenshot OCR with an adjustable opacity slider (0% to 100%).
How does CanvasQuiz pricing compare to ExamGhost in 2026?
CanvasQuiz (routed via AWS Lambda 7xv2cav7t3iceljjbwjn4akknm0kymha.lambda-url.us-east-1.on.aws) charges $14.99/month or $48.99 every 4 months ('Semester — Renews every 4 months', totaling $146.97/year or $587.88 over 4 years). ExamGhost gives every student 50 Free Solves ($0 trial, no credit card required), plus $19/month, $99/year ($8.25/mo Academic Year Pass), or $199 Lifetime.
Does CanvasQuiz work on Blackboard, Moodle, or D2L Brightspace?
No. CanvasQuiz's Chrome Web Store listing explicitly states: 'BUILT FOR CANVAS. ONLY CANVAS... Hand-built for Canvas LMS (instructure.com).' ExamGhost supports Canvas Classic Quizzes, Canvas New Quizzes (LTI 1.3), Blackboard Learn, Moodle, D2L Brightspace, and McGraw-Hill Connect.
What is ExamGhost's emergency panic kill shortcut?
Pressing ⌘+Shift+U (or Ctrl+Shift+U on Windows) instantly purges the closed Shadow DOM overlay from memory in under 8 milliseconds. If a professor or proctor approaches, your screen immediately returns to an unmodified Canvas page.
Don't settle for an unproctored-only button injector.
