What happens when an exam blocks right-click—and your credits expire in 30 days?
Test Bro (testbro.app) was originally built for retired LinkedIn Skill Assessments. On Canvas and Blackboard, it relies on Chrome's right-click menu—and when an exam blocks right-clicking, it forces you to click inside Chrome's Side Panel, immediately logging a window.blur departure in SpeedGrader. Worse, it gives only 5 Free Asks/month, and any unused S/L/XL Ask Credits vanish automatically after 30 days.
ExamGhost triggers silently via root-level keyboard hotkeys (⌘+Shift+S) even when right-click is blocked, keeps SpeedGrader 100% clean, and gives you 50 Free Solves that never expire.
“Paid package lifespan: 1 month. After 1 month, the package will expire automatically.”
Forces you to click Chrome's Side Panel capture button → triggers window.blur in SpeedGrader.
3 Reasons Test Bro Fails on University Exams
Click each tab below to compare Test Bro's right-click context menu lockout, its 30-day credit expiration policy, and its LinkedIn-era architecture against ExamGhost.
Clicking Chrome's Side Panel logs immediate focus loss
On Canvas, Blackboard, and Moodle, Test Bro relies on highlighting text and opening Chrome's right-click context menu (“Select text and ask” or “Select area”).
When an instructor disables right-clicking (oncontextmenu="return false;"), Test Bro's own guide tells you to open Chrome's Side Panel and click its capture button. The moment you click inside Chrome's Side Panel, your quiz tab loses focus and fires window.blur—logging “Stopped viewing the Canvas quiz” in SpeedGrader!
Works 100% when right-click and copy-paste are blocked
ExamGhost never relies on Chrome's right-click context menu or focus-stealing Side Panel. You trigger solves via root-level keyboard shortcuts (⌘+Shift+S or ⌘+B) directly inside the exam tab.
- Bypasses Copy/Right-Click Locks: Unlocks disabled text selection or snips locked diagrams in memory via
⌘+Shift+S. - Focus Shield Active: Suppresses 100% of
window.blurandvisibilitychangeevents.
Buy credits for midterms—watch them vanish before finals
Test Bro gives free users only 5 Asks per month. When you buy an S ($2.99 / 200 Asks), L ($3.99 / 400 Asks), or XL ($5.99 / 800 Asks) package, you might assume those credits stay in your account for the semester.
Instead, Test Bro enforces a 30-day wipeout: “Paid package lifespan: 1 month. After 1 month, the package will expire automatically.” You are forced to re-buy credit packs every single month of the school year.
10x more free solves that never expire
ExamGhost gives every student 50 Free Solves on install—10 times more than Test Bro's 5 monthly asks—and your free solves never expire after 30 days. When you upgrade, every plan includes unlimited solves:
Built for LinkedIn Skill Assessments—not Canvas New Quizzes
If you read Test Bro's Chrome Web Store listing, its flagship one-click `ASK` button was specifically coded for LinkedIn Skill Assessments—a feature LinkedIn permanently retired.
Test Bro v1.1.3 hasn't received an update since December 5, 2025, and lacks native parsers or LTI 1.3 iframe support for 2026 Canvas Classic/New Quizzes, McGraw Hill Connect, or Cengage MindTap.
Native support for Canvas Classic, New Quizzes & all major LMS
ExamGhost is actively engineered every week for 2026 university platforms—including Canvas (Classic & New Quizzes LTI 1.3), Blackboard Ultra, Moodle, D2L Brightspace, McGraw Hill Connect, and Pearson MyLab.
- 3 Display Modes: Invisible 1px Dot, Adjustable Opacity Stealth HUD (0–100%), or Full Step-by-Step Explain Mode.
- Panic Switch (
⌘+Shift+U): Wipes the HUD and memory in 0.05 seconds.

When I opened the Canvas test, the professor had disabled right-clicking, so I had to use Test Bro's Chrome Side Panel capture button—which immediately logged tab departures in SpeedGrader! Then, when I opened the extension a month later for finals, all 340 of my remaining Ask Credits had automatically expired. Switching to ExamGhost gave me 50 free solves that never expire, root hotkeys that work when right-click is blocked, and the $99/year pass keeps my SpeedGrader log 100% clean.”
Frequently Asked Questions: TestBro vs ExamGhost
Why does TestBro fail or trigger blur logs during locked Canvas and Blackboard exams?
Test Bro (testbro.app, v1.1.3) primarily relies on the browser's right-click context menu (‘Select text and ask’ or ‘Select area’) and was originally optimized for deprecated LinkedIn Skill Assessments rather than Canvas LMS. When university exams disable right-clicking via oncontextmenu='return false;', Test Bro instructs users to click the capture button inside Chrome's Side Panel—which immediately removes focus from the quiz tab and fires a window.blur event in Canvas SpeedGrader. ExamGhost operates via root-level keyboard shortcuts (⌘+Shift+S, ⌘+B) and Closed Shadow DOM overlays with Focus Shield.
Do TestBro Ask Credit packages expire?
Yes. Test Bro's paid packages—S package ($2.99 for 200 Ask Credits), L package ($3.99 for 400 Ask Credits), and XL package ($5.99 for 800 Ask Credits)—carry a strict 1-month lifespan (‘After 1 month, the package will expire automatically’). Any unused credits vanish after 30 days. ExamGhost gives you 50 Free Solves on install that never expire, plus unlimited plans ($19/mo, $99/yr, or $199 Lifetime).
Does TestBro trigger Canvas SpeedGrader blur flags?
Yes. Because Test Bro v1.1.3 has not been updated since December 5, 2025 and does not hook window.blur or document.visibilitychange events, opening its popup window or Chrome Side Panel causes Canvas to register a ‘Stopped viewing the Canvas quiz’ log entry. ExamGhost features Focus Shield, intercepting 100% of window blur events.
Can ExamGhost solve questions locked inside images or diagrams?
Yes. ExamGhost includes Snap-It Multimodal OCR (⌘+Shift+S), allowing you to snip any diagram, chart, or locked question directly inside the tab without opening Chrome's context menu or Side Panel, returning answers in 0.3 seconds.
