Before you spend $24.99/mo or $149.99 on CanvasHack
Why pay $149.99 for a tab blocker that can't even answer questions?
Most students assume CanvasHack is an AI quiz solver. It isn't. Even after paying $24.99/mo or $149.99, CanvasHack only masks tab switches—forcing you to manually copy, switch tabs, and paste every single question into ChatGPT yourself.
ExamGhost gives you both: full Focus Shield tab-blur protection plus a built-in 0.3-second inline AI & screenshot solver that auto-fills or highlights answers right on your quiz page. Start with 50 Free Solves—no credit card needed.
“Not yet, but you can safely switch tabs to search, copy, or use tools like GPT without being flagged.”
- Blocks tab-blur logs
- Zero AI solver (manual GPT)
- Zero OCR for math/graphs
- 0 free trial solves
- Focus Shield blur block
- 0.3s Inline AI Solver
- Snap-It OCR (⌘+Shift+S)
- 50 Free Solves upfront
Double-click any question to auto-fill in 0.3s. With CanvasHack, you waste 40+ seconds copying and pasting into ChatGPT.
You don't need to leave your exam tab when the AI lives inside a closed Shadow DOM right on your quiz page.
Can't copy an image or locked formula? Press ⌘+Shift+S and drag over any graph or integral.
Test ExamGhost on 50 real questions for $0 before upgrading ($19/mo, $99/yr, or $199 Lifetime). CanvasHack has zero free trial.
INTERACTIVE TEARDOWN · CLICK TABS BELOW
See what happens during a real 50-question timed midterm.
Switch between the three tabs below to compare your live exam workflow, what your professor sees in Canvas SpeedGrader, and what you actually pay over a semester.
6 Manual Steps Per Question
- 1Drag cursor to highlight question text — triggers
document.onselectionchange& fails on image diagrams. - 2Press Ctrl+C to copy — Canvas & lockdown scripts can still log clipboard copy events.
- 3Switch to a separate ChatGPT tab — unsafe if a TA walks behind you in a lecture hall or computer lab.
- 4Paste choices A, B, C, D & wait 15–30s — while your Canvas cursor sits frozen for 40 seconds.
- 5Switch back & manually click the radio button — repeating this 50 times burns 35+ minutes of exam time!
1 Double-Click Right on the Page
No highlighting, no copying, no switching tabs. ExamGhost reads the question silently in-memory and applies your chosen delivery method in 0.3 seconds:
Draw a quick crop box over any diagram, organic chemistry structure, or locked iframe. Our built-in Mathpix STEM Vision decodes and solves it on-screen without ever leaving the quiz.
Instantly toggles the entire extension off and flushes memory in under 8ms—zero visible trace on your screen.
Why Blocking Tab-Blur Alone Still Leaves Behavioral Flags
Even though CanvasHack suppressed window.blur, copying question text and leaving the quiz viewport motionless for 43 seconds while chatting with GPT in another tab creates an obvious pattern.
ExamGhost solves the question right inside a closed Shadow DOM root without copying text to your clipboard or leaving the window. Plus, Focus Shield blocks accidental tab blurs automatically.
With CanvasHack, you pay $149.99—and still have to pay $20/mo for ChatGPT Plus.
Because CanvasHack has no AI model of its own, using it for college STEM courses requires paying for a separate ChatGPT Plus or Claude Pro subscription ($20/month = $80/semester) on top of CanvasHack's $24.99/mo or $149.99 fee.
ExamGhost includes everything in one pass: frontier multimodal AI, Mathpix LaTeX OCR, Focus Shield, and 20+ LMS support—starting with 50 Free Solves so you never buy blind.

“I almost paid $149.99 for CanvasHack thinking it solved Canvas quizzes, until I read their FAQ admitting it doesn't give answers directly. My roommate showed me ExamGhost—I tested the 50 Free Solves on my Data Structures quiz, double-clicked every question for instant 0.3s answers, and grabbed the $99/yr pass.”
Frequently Asked Questions
Straight answers on CanvasHack's features, pricing, and how ExamGhost works.
Does CanvasHack solve exam questions automatically?
No. On canvashack.com under the FAQ 'Can it give me answers directly?', CanvasHack explicitly states: 'Not yet, but you can safely switch tabs to search, copy, or use tools like GPT without being flagged.' It has zero AI model, zero OCR vision engine, and zero question solver. ExamGhost solves questions directly on your screen in 0.3 seconds via double-click or Snap-It OCR.
Can professors still catch CanvasHack users in SpeedGrader?
Yes. While CanvasHack (v1.9.1) blocks basic window.blur events, forcing you to highlight text, press Ctrl+C, and spend 30–45 seconds in a separate ChatGPT tab leaves clipboard copy events and unnatural cursor inactivity gaps in quiz telemetry. ExamGhost solves questions right on the page in 0.3 seconds so your mouse never leaves the exam.
How much does CanvasHack cost compared to ExamGhost?
CanvasHack charges $24.99/month or $149.99 one-time via server.canvashack.com solely for tab blocking and previous-attempt answer saving—with zero free trial and zero AI. ExamGhost gives every student 50 Free Solves ($0 trial, no credit card required), followed by $19/mo Monthly Pass, $99/yr Academic Year Pass ($8.25/mo), or $199 Lifetime Degree Pass with full Focus Shield AND 0.3s AI solving.
Does CanvasHack work on Blackboard, Moodle, or McGraw-Hill?
No. CanvasHack only runs on Canvas LMS domains. ExamGhost works across 20+ platforms including Canvas Classic, Canvas New Quizzes (LTI 1.3), Blackboard Learn & Ultra, Moodle, D2L Brightspace, McGraw-Hill Connect, and Pearson.
How does ExamGhost stay invisible during screen-shares or computer lab exams?
ExamGhost renders inside a closed Shadow DOM container and gives you 3 instant Display Modes: Invisible Mode (auto-fills the answer with zero on-screen UI), Stealth Mode (quiet micro-cursor), and Explain Mode (step-by-step proof drawer). Pressing ⌘+Shift+U toggles the entire extension off in under 8ms.
