Why pay $5/mo for a Canvas solver that leaves Tab-Switch Detection turned on?
CanvasPass looks cheap at first glance—until you read the fine print on canvaspass.sbs. Both its Free ($0) and Starter ($5/mo) plans explicitly turn OFF the Tab-Switch Blocker, deduct 10 credits per Smart solve (turning 800 credits into just 80 questions), and charge $25/mo extra for a Windows-only desktop app.

See what each CanvasPass plan on canvaspass.sbs actually gives you once you factor in per-question credit deductions, character limits, and security paywalls.
No Tab-Switch Blocker + No Image Support + 800-Char Cutoff
- Tab-Switch Blocker is OFF (`✗`): Testing CanvasPass Free on a live Canvas quiz logs every blur and tab switch in SpeedGrader.
- Zero Image / Diagram Support: Cannot read graphs, chemistry structures, or screenshot crops.
- 800-Character Limit: Truncates any question longer than a single short paragraph (10 solves per 12 hours).
50 Full Solves + 4-Layer Focus Shield + Snap-It Vision Included
- Focus Shield Included for $0: We never paywall safety—your 50 free solves have the exact same anti-blur shield as our Lifetime pass.
- Includes Snap-It Vision (`⌘+Shift+S`): Test diagram, graph, and equation OCR before paying a cent.
- Zero Character Truncation: Reads full case studies and multi-part tables.
Still Disables Tab-Switch Blocker & Deducts 10 Credits per Smart Solve
- Tab-Switch Blocker Still OFF (`✗`): Even after paying $5/mo, CanvasPass leaves Tab-Switch Blocker, Kiosk Spoof, and Answer Saver disabled.
- 10 Credits per Smart Question: Smart Mode (Claude Sonnet) costs 10 credits/solve—so 800 credits runs out after just 80 questions (less than two 50-question exams).
- 2,000-Character Cap: Long nursing vignettes, history passages, or accounting tables get cut off mid-sentence.
Unlimited Smart Solves + Full Focus Shield + Zero Credit Anxiety
- No Credit Multipliers: Solve 80 questions or 8,000 questions—every single solve uses our top-tier STEM & reasoning models.

window.blur,visibilitychange, and mouse-leave logs across all 20+ LMSs. - 14-Day 100% Money-Back Guarantee: Plus 50 Free Solves before you ever pull out a card.
Unlocks Tab Blocker, But Caps You at ~187 Smart Solves & Canvas Only
- 8 Credits per Smart Solve: Taking 4 classes with weekly 25-question quizzes (400 questions/mo) requires 3,200 credits—forcing you to buy $5 top-up packs mid-month.
- Fails on Embedded Publisher Portals: Doesn't work when a Canvas course launches McGraw-Hill Connect, Pearson MyLab, Cengage, or WebAssign.
- Injects Buttons Into Canvas DOM: Appends custom AI button elements inside
.question_holderunless manually toggled.
Costs Less per Month Than CanvasPass Pro—With Unlimited Solves Everywhere
- $8.25/mo on Annual Pass ($99/yr): Lower monthly cost than CanvasPass Pro ($10/mo) with zero credit top-ups ever.
- Works on Every LMS & Publisher Portal: Canvas, Blackboard, Moodle, D2L, McGraw-Hill, Pearson, Cengage, and WebAssign.
- Closed Shadow DOM: Never injects detectable AI buttons into Canvas's host HTML.
Injects Visible "AI Buttons" Into Canvas HTML
CanvasPass describes itself as an extension that "adds a small AI button next to each quiz question on Canvas LMS." Appending custom <button> elements directly inside Canvas's .question_holder DOM makes it visible to anyone walking past your desk and detectable via MutationObserver scripts.
Zero Injected Buttons · 0.3s Double-Click + Closed Shadow DOM
ExamGhost never alters Canvas's question headers or injects visible buttons. Simply double-click any question text: in Invisible Mode, it auto-selects the right choice silently; in Stealth Mode, it briefly highlights the correct answer; and pressing ⌘+Shift+U flushes everything in under 8ms.

Frequently Asked Questions
Everything students ask about CanvasPass credits, tab-switch paywalls, and ExamGhost.
What happened to canvaspass.app, and is canvaspass.sbs the same product?
Yes. The original canvaspass.app domain no longer resolves in DNS and migrated to canvaspass.sbs, linking to the CanvasPass Chrome extension (ID: hfeeodhaiedlmahknjhcidhcphmnjeam) and Firefox add-on.
Does CanvasPass include a Tab-Switch Blocker on its Free or $5/month Starter plan?
No. According to CanvasPass's pricing table on canvaspass.sbs, both the Free ($0) plan and the Starter ($5/month) plan explicitly disable the Tab-Switch Blocker, Kiosk Spoof, and Answer Saver. Students must upgrade to at least the Pro ($10/month) tier before CanvasPass blocks Canvas quiz tab-switching events. ExamGhost includes its full Focus Shield (blocking visibilitychange, window.blur, and focusout) on every tier—including the 50 free trial solves.
How many questions can you actually solve on CanvasPass with its credit system?
While CanvasPass advertises 800 credits/month on Starter ($5/mo) and 1,500 credits/month on Pro ($10/mo), each question costs multiple credits depending on the AI mode. On Starter, 'Fast Mode' (Gemini Flash) deducts 5 credits per question (160 questions total), and 'Smart Mode' (Claude Sonnet) deducts 10 credits per question—meaning 800 credits only covers 80 Smart solves per month. On Pro ($10/mo), Smart Mode deducts 8 credits per question (187 Smart solves/month).
What is OverlayPass, and does it work on MacBooks?
OverlayPass is a separate desktop overlay application sold on canvaspass.sbs for an additional $25/month subscription. However, OverlayPass is strictly Windows-only ('Standalone Windows desktop app') and does not run on macOS, Chromebooks, or Linux. ExamGhost runs natively inside any Chromium browser on both macOS and Windows with zero extra desktop subscription.
Does CanvasPass work on Blackboard, Moodle, McGraw Hill Connect, or Pearson MyLab?
No. CanvasPass is hardcoded specifically to inject AI buttons next to quiz questions on Instructure Canvas LMS. Even secondary classroom tools listed on its website (Blooket, Kahoot, Quizizz, and IXL) are marked as 'In Development · Unknown (No release date yet).' ExamGhost's Snap-It Vision OCR and Focus Shield work across Canvas, Blackboard Ultra, Moodle, D2L Brightspace, McGraw Hill Connect, Pearson MyLab, Cengage MindTap, and WebAssign.
