Quizplus's Chrome Extension Is Delisted & Static Test Banks Fail When Numbers Change.
Quizplus (quizplus.com) built its name on ~20 million static publisher test-bank questions. In 2026, two things break that workflow on live exams: first, Quizplus's official Chrome extension has been delisted from the Chrome Web Store, forcing you to switch tabs and trigger Canvas window.blur logs; second, whenever a professor randomizes a single STEM variable (e.g., r = 4 m → r = 7.5 m), Quizplus returns the wrong static key while charging up to $24.99/month. Here is why students switch to ExamGhost AI.

Why Static Publisher Test Banks Break When Professors Randomize Variables
Quizplus indexes roughly 20 million static Q&A items and 300,000+ preset quizzes pulled from legacy Cengage, Pearson, and McGraw Hill textbook editions. When you search a question on quizplus.com, it performs a text-similarity lookup against those static pages.
In 2026, university courses on Canvas New Quizzes, WebAssign, ALEKS, and Pearson MyLab use algorithmic question generators where every student gets different numbers, negated stems, or embedded diagrams. If your textbook bank solved for r = 4 m, Quizplus gives you the wrong answer for r = 7.5 m. ExamGhost AI reads your exact on-screen variables and diagrams via 0.3s Mathpix Vision OCR and computes the live derivation from scratch.
- • Algorithmic STEM problems with randomized numbers per student
- • Non-selectable circuit schematics, chemistry rings & graphs
- • Original professor-written midterms not found in publisher banks
- • Computes exact answers for your specific live numbers in 0.3s
- • Crosshair Snap-It Vision OCR reads any locked graph or table
- • Shows both the final answer and step-by-step verification
Quizplus's Chrome Extension Is Dead—Forcing You to Switch Tabs on Monitored Quizzes
When we audited Quizplus's official Chrome Web Store listing in 2026, the store URL redirected to /detail/empty-title/ with an item-removed status code—confirming the extension has been delisted.
Without a working in-tab stealth extension, using Quizplus during a Canvas or Blackboard exam requires highlighting the question text, copying it, and switching to a second browser tab at quizplus.com. Every single tab switch dispatches window.blur, visibilitychange, and pagehide events that Canvas SpeedGrader logs with exact timestamps. ExamGhost AI is an active Manifest V3 stealth extension that solves inside your exam tab within a closed Shadow DOM root while blocking all focus-loss events.
Stop Paying $24.99/Month ($299/Year) to Unblur Static Textbook Keys
When you search a question on quizplus.com, the correct multiple-choice option and explanation are blurred behind a paywall. Unlocking full test-bank access requires entering a payment method for a short 3-to-7 day trial that auto-renews at $20 to $24.99/month (or ~$55.99/quarter)—costing up to $299.88 per year.
ExamGhost AI gives you 50 Free Question Solves ($0, no credit card required) with unblurred answers, full step-by-step math derivations, and active Canvas Focus Shield included. Upgrading to unlimited solves costs just $19/month, $99/year ($8.25/mo — saving up to $200/yr over Quizplus), or $199 one-time for a Lifetime Degree Pass backed by our 14-day 100% money-back guarantee.

To be completely fair, Quizplus was built for untimed, open-book homework review where an instructor pulls verbatim questions straight out of an older publisher test bank:
- •Studying untimed intro-level flashcards or reviewing standard publisher chapter quizzes from 2018–2023 textbook editions.
- •Looking up verbatim multiple-choice study guides outside of a monitored LMS browser session.
When You Need ExamGhost Instead
- Timed Canvas Classic & New Quizzes, Blackboard Ultra, Moodle, D2L Brightspace, McGraw Hill Connect, or Pearson MyLab exams where tab-switching is logged.
- Randomized STEM problems, circuit diagrams, accounting tables, or professor-written exams that do not exist in static textbook banks.
- Transparent pricing: start with 50 Free Question Solves ($0), then pick $19/mo, $99/yr ($8.25/mo), or $199 Lifetime.
Frequently Asked Questions: Quizplus vs ExamGhost
What happened to the Quizplus Chrome Extension?
During our 2026 Chrome Web Store audit, navigating to the official Quizplus extension URL redirects to /detail/empty-title/ with an item-removed error status—confirming the extension has been delisted from the store. Students using Quizplus are forced to manually copy-paste questions into quizplus.com in a separate browser tab.
Why does Quizplus fail when professors use algorithmic or randomized numbers in Canvas?
Quizplus is a pre-indexed textbook test-bank repository of around 20M+ static Q&A records and roughly 300,000 preset quizzes. If a professor changes a single numeric parameter in McGraw Hill Connect, WebAssign, or Canvas New Quizzes, Quizplus either returns no match or shows the answer for a different number set. ExamGhost uses live multimodal AI and Mathpix OCR to compute the exact answer for your specific variables in 0.3 seconds.
Can Canvas SpeedGrader detect when I switch tabs to search Quizplus.com?
Yes. Because the Quizplus Chrome extension is delisted and lacks a Focus Shield, searching quizplus.com requires leaving your active Canvas quiz tab. Every tab switch fires window.blur, document.visibilitychange, and pagehide events that Canvas logs with exact timestamps. ExamGhost intercepts and suppresses these events inside a closed Shadow DOM.
How does Quizplus pricing compare to ExamGhost in 2026?
Quizplus locks full test-bank answers behind a recurring subscription ranging from $20 to $24.99/month (or ~$55.99/quarter) after a short 3-to-7 day trial, costing up to $299/year. ExamGhost gives you 50 Free Question Solves ($0) with no credit card required, plus transparent flat options: $19/month, $99/year ($8.25/mo), or a $199 one-time Lifetime Degree Pass.
Replace Static Test Banks With Live 0.3s In-Tab AI
Don't switch tabs to search outdated textbook banks. Test ExamGhost AI with 50 Free Question Solves ($0, no card required) or unlock unlimited access for $19/month or $99/year ($8.25/mo).
