QuestionAI is built for PDF chat & K-12 homework—not monitored college exams.
With 10M+ users, QuestionAI (questionai.com) is great for summarizing PDFs and scanning paper worksheets on mobile. But on live university quizzes, its text-highlight popups, 400px Copilot sidebar, and public Google-indexed question feed create serious academic integrity risks. ExamGhost solves Canvas, Blackboard, and Moodle questions inline in 0.3 seconds inside a closed Shadow DOM—with zero public indexing and 50 Free Solves.
3 Reasons Why QuestionAI Fails During Timed Canvas & Blackboard Exams
Select any tab below to compare QuestionAI's public question directory, Copilot sidebar telemetry, and raw LaTeX text scraping against ExamGhost.
QuestionAI Publicly Indexes Student Prompts—Where Professors Can Google Them
Scroll to the bottom of questionai.com and you will find thousands of verbatim student quiz questions indexed publicly across Math, Biology, History, and Business—often complete with raw "Question 25 of 40" headers. When professors Google their custom exam prompts to check for leaks, public Q&A aggregators expose the exact question text and timestamp.
Turns user-submitted homework and quiz questions into public SEO pages indexed by Google.
Every Double-Click and Snap-It OCR query is processed in volatile memory and discarded immediately—never indexed or published.
Mangled Copied MathJax Strings vs. 0.3s Mathpix Visual OCR
When you highlight or copy-paste a Canvas math question containing MathJax or embedded equation images into QuestionAI, it frequently mangles fractions, matrices, and definite integrals into broken strings (e.g., int 1 1 left x frac 4 3)—causing wrong answers on Calculus, Physics, and Chemistry exams. ExamGhost's Snap-It OCR (⌘+Shift+S) reads the rendered visual equation directly.
Strips superscripts, integral bounds, and chemical bond angles when copying DOM text into the chat sidebar.
Captures rendered LaTeX, circuit diagrams, and organic chemistry structures directly in 0.3 seconds.

Frequently Asked Questions: QuestionAI vs ExamGhost
Answers on QuestionAI's Copilot extension, public question indexing, and ExamGhost's stealth architecture.
How does QuestionAI differ from ExamGhost for college quizzes?
QuestionAI (questionai.com) is a general-purpose K-12 and homework chatbot featuring a PDF Solver, Textbook Summarizer, Calculator, and a browser Copilot sidebar. ExamGhost is a specialized university exam solver built for Canvas, Blackboard, Moodle, and D2L that solves questions inline via Double-Click or Snap-It OCR inside a closed Shadow DOM without opening a detectable sidebar.
Why does QuestionAI's Chrome sidebar trigger flags on Canvas SpeedGrader?
To use QuestionAI on a webpage, students typically highlight question text (triggering a floating Copilot icon) or click into QuestionAI's right-hand drawer. Both actions fire selectionchange and window.blur events, and the sidebar resizes the browser viewport. ExamGhost's Focus Shield blocks window.blur and visibilitychange events and never alters page layout.
Does ExamGhost publish my exam questions publicly like QuestionAI's subject directory?
Never. QuestionAI's website hosts a massive public directory of user-submitted questions across Math, Biology, History, and Business that anyone (including professors) can find via Google search. ExamGhost processes all Double-Click and Snap-It OCR queries over ephemeral, zero-retention encrypted channels and never indexes student questions.
What are ExamGhost's current pricing plans compared to QuestionAI Plus?
QuestionAI offers a basic free tier with lower-tier AI models and charges recurring monthly fees for QuestionAI Plus. ExamGhost gives every student 50 Free Question Solves with full Focus Shield and Snap-It OCR, followed by transparent plans: $19/month (Midterm Sprint), $99/year ($8.25/mo Academic Year Pass), or $199 one-time for the Lifetime Degree Pass.
