Double Check AI vs ExamGhost: 244 Real Users, 5-Question Caps & Auto-Click DOM Traces
Visit doublecheckme.com and you'll see bold banners claiming “1,200+ students use Double Check” alongside an urgent “ACT FAST” countdown timer. Check Google's official Chrome Web Store listing (ciiaplbmocogjcakmllebilamknkfckg) and the truth is very different: only 244 active users and 13 ratings, a strict 5-question/24hr free cap, and an injected DOM button that programmatically clicks radio inputs (isTrusted: false).

4 Reasons Students Drop Double Check AI for ExamGhost
We inspected the live doublecheckme.com marketing funnel alongside the actual ciiaplbmocogjcakmllebilamknkfckg extension behavior inside Canvas and McGraw-Hill. Click each tab below to inspect the receipts.
“Press the Button and It Automatically Selects the Right Answer”
Double Check AI brags on its homepage that you simply press an injected button inside your quiz and the extension automatically selects the answer option for you. In 2026 LMS environments, that workflow fails two separate security checks:
- 1. Host DOM Mutation: Injecting a visible
<button>next to quiz questions triggers LMSMutationObserverlisteners. - 2. Untrusted Synthetic Clicks: When JavaScript clicks a radio button for you, Chrome marks the event
event.isTrusted = falsewithclientX: 0, clientY: 0.
Zero Injected Buttons + 100% Authentic Hardware Clicks
ExamGhost is triggered by customizable keyboard shortcuts (⌘+Shift+A or ⌘+Shift+S) rather than cluttering your quiz page with detectable buttons. It renders the verified answer inside a Closed Shadow DOM root that page scripts cannot read, and lets you click the radio button yourself so every click is isTrusted: true.
- ✓ No buttons injected next to Canvas/Blackboard question headers
- ✓ You click the answer yourself → genuine mouse coordinates & timing
- ✓ ⌘+Shift+U Panic Wipe unmounts the entire UI in <16ms
Cut Off After Question #5 With a 24-Hour Cooldown
Double Check AI's free plan only allows 5 questions every 24 hours. Since even a short college reading quiz has 10 to 20 questions, students install the extension, start a timed quiz, and hit a paywall lockout on Question #6 while the exam timer is ticking down.
50 Free Solves Upfront — Finish Multiple Full Quizzes for $0
ExamGhost gives every student 50 full AI solves immediately upon installation—with zero credit card required and no artificial 24-hour drip limit. You can test ExamGhost across two or three complete 20-question quizzes before ever deciding whether to upgrade.
Fake Countdown Timers & 5x Inflated User Numbers
When evaluating a browser extension that has access to your university LMS session, honesty matters. On doublecheckme.com, the hero section claims “1,200+ students use Double Check” and “150k+ Questions Solved” with a hardcoded “ACT FAST: Offer valid until October 20” urgency bar.

Every modern browser implements the W3C UI Events specification where user actions triggered by physical hardware set Event.isTrusted = true, whereas actions triggered by extension scripts calling element.click() or input.checked = true set Event.isTrusted = false.
Extensions that brag about “automatically selecting the right answer” when you click their injected button expose your account to trivial script-click detection. ExamGhost never auto-clicks host inputs.
“I downloaded Double Check AI from a TikTok clip because the site said 1,200+ students used it. First red flag was seeing only 244 users on the Chrome Store. Second red flag was starting my 20-question Canvas quiz and getting locked out after Question 5 unless I paid immediately. Plus it puts a giant button right inside Canvas and auto-clicks the radio button, which sketches me out with SpeedGrader logs. Uninstalled it, grabbed ExamGhost's 50 free solves, and finished both my Canvas and McGraw-Hill quizzes with zero buttons injected into the page.”
Double Check AI vs ExamGhost: Common Questions
1. How many students actually use Double Check AI on the Chrome Web Store?▼
Although doublecheckme.com advertises “1,200+ students use Double Check” and “150k+ Questions Solved,” its official Chrome Web Store listing (AI Homework Helper - Double Check AI, ID: ciiaplbmocogjcakmllebilamknkfckg) shows only 244 active users and 13 ratings.
2. Why is Double Check AI's automatic answer selection risky on Canvas and Blackboard?▼
On doublecheckme.com, a featured testimonial states: “i literally just press the button and it automatically selects the right answer lol.” This reveals two detection vectors: first, the extension injects a visible button directly into the LMS host DOM; second, programmatically clicking a radio button sets event.isTrusted to false in browser event listeners. ExamGhost never injects buttons into the host DOM and never auto-clicks inputs—it renders answers inside a Closed Shadow DOM so you click naturally with genuine hardware events.
3. How many free questions does Double Check AI give compared to ExamGhost?▼
Double Check AI restricts free users to just 5 questions every 24 hours—not enough to finish a single 10-question Canvas quiz. ExamGhost gives every student 50 Free Solves upfront with zero credit card required and no 24-hour lockout.
4. Does Double Check AI protect against Canvas tab-switching and window blur logs?▼
No. Double Check AI does not include a prototype-level Focus Shield to intercept window.blur, focusout, or document.visibilitychange events. ExamGhost includes an always-on Focus Shield plus a ⌘+Shift+U Panic Wipe hotkey.
