A Mobile Camera App Paired to a v0.1.13 Extension Won't Hide You on Canvas.
Students searching for Quizard usually run into two completely different products: Quizard AI — Homework Tutor (quizard.ai / usequizard.com), a mobile photo scanner that makes you “Link Device” from your phone just to unlock its Cmd+Shift+K Chrome companion—and Quizard.io, an offline PDF flashcard generator with no browser extension at all. Neither blocks Canvas SpeedGrader focus-loss telemetry.
Built by Michael Giardino as a mobile photo scanner (“Take a picture, get an answer”). Requires downloading the iOS/Android app and syncing via “Link Device” before its Cmd/Ctrl+Shift+K Chrome overlay works—firing window.blur on every crop.
An offline study web app that turns lecture PDFs and slides into review flashcards and practice quizzes ($7.99/mo or $39.99/yr, capped at 300 questions/day). Cannot read or assist inside live Canvas, Blackboard, or Moodle exams.
Desktop-native Chrome extension with Closed Shadow DOM isolation, 8-layer focus-loss event blocking, and 3-model AI consensus—starting with 50 free solves and no phone sync required.
3 Reasons Students Drop Quizard AI for ExamGhost
Click any tab below to inspect how Quizard AI's mobile companion architecture, high-school SAT tuning, and weekly App Store billing compare against ExamGhost.
Why Syncing a Phone App & Pressing Cmd+Shift+K Flags Your Canvas Log
Quizard AI's Chrome extension hasn't moved past version 0.1.13 because it was built as a secondary add-on to its mobile camera app. Before you can solve a single desktop question, you must install Quizard on your phone, start a mobile subscription, and pair your browser via “Link Device.”
Worse, triggering Quizard AI on a quiz page via Cmd/Ctrl + Shift + K mounts an unshielded selection overlay directly over the page without intercepting window.blur or visibilitychange. Canvas SpeedGrader immediately records that you left the assessment window.
Benchmarked on High-School SAT Math vs Built for University STEM Finals
On Quizard AI's own website, its headline accuracy chart is benchmarked against high-school SAT Math questions. That works fine for secondary-school algebra worksheets, but university exams test multivariable calculus, organic chemistry stereochemistry, thermodynamics, and multi-table corporate finance.
Instead of trusting a single mobile OCR pass, ExamGhost extracts clean DOM + high-DPI math context and dispatches every question simultaneously to GPT-5.4, Claude Sonnet 4.6, and Gemini 3.1 Pro, returning a consensus-verified answer with a live confidence score.
Optimized around mobile photo snaps and SAT-level algebra. No multi-model cross-check when reading dense LaTeX, circuit diagrams, or accounting tables.
Queries GPT-5.4 + Claude Sonnet 4.6 + Gemini 3.1 Pro in parallel. Shows when all 3 models agree and includes full step-by-step derivations.
~$6.99/Week App Store Subscriptions & Notion Legal Pages vs Transparent Pricing
Because Quizard AI funnels users through iOS App Store (ID 1667996582) and Google Play in-app purchases, students frequently get locked into ~$6.99/week (~$363/year) or $9.99–$19.99/month mobile auto-renewals—while Quizard AI's official Terms and Privacy Policy live on a free Notion link (lovely-vault-f15.notion.site).
Meanwhile, if you accidentally subscribe to Quizard.io ($7.99/mo or $39.99/yr), you get an offline flashcard maker capped at 300 questions per day with zero browser extension support. ExamGhost gives you 50 free solves upfront, transparent $8.25/mo annual billing, or a $199 Lifetime pass.
