Why Risk a 72-Hour Auto-Billing Trial ($5.99/Wk) and an Unshielded Study Wrapper?
TestWhiz (testwhiz.co) bundles 6 study tools—PDF Chat, YouTube Video Chat, Flashcards, Notes, Worksheets, and Quizzes—behind a 3-day free trial that auto-converts into $5.99/week ($311.48/year) or $12.99/month. While its homepage announces “We replaced our old AI solver extension with a new one!” and promises an “Incognito mode,” it still lacks a Canvas window.blur Focus Shield. Here is how it compares to ExamGhost AI.

What Happens When TestWhiz's 3-Day Free Trial Expires?
On testwhiz.co/pricing, every tier—Weekly ($5.99/week), Monthly ($12.99/month), and Semester ($39.99/semester)—gates access behind a 3-day free trial (“Try TestWhiz for FREE for 3 days. Cancel anytime.”). If you forget to cancel within 72 hours on the Weekly plan, you are billed $5.99 every 7 days—which equals $23.96/month or $311.48/year.
ExamGhost AI never puts a 72-hour ticking clock on your trial. You get 50 Free Question Solves ($0) with no credit card required. When you want unlimited access, our $19/month Monthly Pass, $99/year Academic Year Pass ($8.25/mo), and $199 one-time Lifetime Degree Pass are backed by an unconditional 14-day 100% money-back guarantee.

Why TestWhiz's “Incognito Mode” Doesn't Stop Canvas Quiz Logs
At the top of testwhiz.co, a banner announces: “New Feature Alert: We replaced our old AI solver extension with a new one!” In its FAQ, TestWhiz states that “Incognito mode ensures your activity remains private.”
However, Canvas, Blackboard, and D2L Brightspace do not check your local extension history—they monitor window.onblur, document.visibilityState, and document.hasFocus(). Clicking outside the active quiz DOM or switching tabs to use TestWhiz's PDF/YouTube chat immediately logs “Stopped viewing the Canvas quiz-taking page.” ExamGhost AI's 4-Layer Focus Shield neutralizes those exact event listeners in memory and renders inside a closed Shadow DOM root.

TestWhiz is designed primarily as a 6-tool web portal where you upload syllabus PDFs or paste YouTube lecture URLs to generate flashcards, study notes, printable worksheets, and practice quizzes. While those features are handy for pre-exam review, you can already summarize PDFs and YouTube transcripts for free in standard AI chat tools.
Instead of padding our dashboard with worksheet generators, ExamGhost AI dedicates 100% of its engineering to 24 live LMS stealth and solving capabilities—delivering 0.3s Multimodal Vision OCR for Calculus integrals, Organic Chemistry structures, circuit schematics, and McGraw-Hill SmartBook prompts directly inside your active exam tab.
- • Chatting with YouTube lecture videos and generating printable study worksheets before exam week
- • Using a basic highlight/screenshot helper on unmonitored homework where tab switches aren't logged
- • Live timed midterms & finals on Canvas, Blackboard, Moodle, D2L & SmartBook
- • 0.3s Snap-It Vision OCR for complex STEM diagrams, graphs, and locked iframes
- • Zero-trace closed Shadow DOM HUD + 4-Layer Focus Shield

Why did TestWhiz replace its old AI solver Chrome extension?
On the live testwhiz.co homepage, a prominent banner announces: “New Feature Alert: We replaced our old AI solver extension with a new one!” While the replacement extension restores basic text-highlight and screenshot solving, it remains a companion to a 6-tool study dashboard rather than a dedicated LMS stealth engine.
Does TestWhiz's “Incognito mode” stop Canvas Quiz Logs from detecting tab switches?
No. While TestWhiz's FAQ claims that “Incognito mode ensures your activity remains private,” hiding local popup state does not block browser focus telemetry. When you click outside the active quiz DOM or switch tabs to use TestWhiz's PDF Chat or YouTube Video Chat, Canvas LMS fires window.blur and visibilitychange events. ExamGhost blocks those telemetry listeners via its 4-Layer Focus Shield.
How much does TestWhiz actually cost after its 3-day free trial?
According to testwhiz.co/pricing, TestWhiz offers a 3-day free trial that converts into recurring plans: $5.99/week ($311.48/year), $12.99/month ($155.88/year), or $39.99/semester. ExamGhost gives you 50 Free Question Solves ($0) with no credit card and no 72-hour expiration timer, followed by $19/month, $99/year ($8.25/mo), or a $199 one-time Lifetime Degree Pass.
Can I test ExamGhost's Focus Shield before installing anything?
Yes. You can launch our interactive Live Canvas Quiz Log Sandbox Demo right in your browser to watch how Canvas records window.blur and visibilitychange events when Focus Shield is OFF versus when ExamGhost's 4-Layer Focus Shield is ON.
