SnapGPT's “Subtle Mode” Is Just opacity: 0. ExamGhost Runs in a Closed Shadow DOM.
After snapgpt.io went offline, SnapGPT migrated to snapgpt.me (plus a fallback CloudFront mirror for blocked campus Wi-Fi). When we audited its live CSS and scripts, we discovered that SnapGPT's advertised “Subtle mode” simply applies .invisible { opacity: 0; } to a 52×52px button left sitting in the page DOM—while painting green #2ecc71 borders directly onto your Canvas answer choices and logging sessions via OpenReplay.

Hiding a button from human eyes with CSS transparency is not the same as isolating an extension from LMS scripts. Select an audit tab below to compare SnapGPT against ExamGhost AI.
“Still There — Just Transparent”: How Subtle Mode & Autopilot Mutate Your Quiz Page
SnapGPT pins a 52px × 52px viewfinder button (css/button.css) at the bottom-left corner of your browser (left: 16px; bottom: 16px). When you enable “Subtle mode,” SnapGPT's own interactive demo explains: “Still there — just transparent. Click it.” Under the hood, it merely applies .invisible { opacity: 0; }.
Any school script running document.querySelectorAll or a MutationObserver doesn't care about CSS opacity—it sees the injected button node immediately. Worse, when SnapGPT reveals or auto-solves an answer, it either paints a green #2ecc71 border (.correct) directly onto Canvas .question_holder elements or opens a full-height Sidebar Chat that triggers window.blur and viewport resize logs.

Although SnapGPT's footer claims “Learning first. Privacy always,” inspecting the production HTML on snapgpt.me reveals a heavy third-party surveillance stack: it loads OpenReplay session recording (replay.snapgpt.me), PostHog analytics, and Reddit Ads tracking pixels. Even more concerning, its embedded admin navigation menu contains links for: “/admin/chats/ — Customer chats: Browse and search every conversation” and “replay.snapgpt.me — Session replay: OpenReplay recordings.”
On top of privacy concerns, SnapGPT's original snapgpt.io domain is dead, and snapgpt.me is frequently blocked on university Wi-Fi firewalls—forcing SnapGPT to display a corner banner telling students to use a raw CloudFront mirror URL. ExamGhost AI processes every solve in ephemeral edge RAM with zero stored chat logs and an instant Esc Panic RAM Flush.

When I saw that 'Subtle mode' just makes the bottom-left button invisible while still painting green borders directly onto my Canvas quiz answers, I uninstalled it immediately.

Frequently Asked Questions: SnapGPT vs ExamGhost
What happened to snapgpt.io and why is snapgpt.me blocked on campus networks?
The original snapgpt.io domain is offline (DNS lookup fails with no such host). SnapGPT now operates at snapgpt.me and displays a corner warning banner directing students on blocked university networks to an alternate CloudFront mirror URL.
Does SnapGPT's “Subtle mode” hide the extension from Canvas or proctoring scripts?
No. As SnapGPT's own codebase and interactive demo explain (“Still there — just transparent. Click it.”), Subtle mode merely applies opacity: 0 to its 52×52px bottom-left camera button while leaving the button node in the live DOM and mutating quiz option styles (.correct) when revealing answers. ExamGhost encapsulates its entire HUD inside a closed Shadow DOM with zero host-page CSS mutations.
Does SnapGPT log customer chats or session replays?
Inspecting snapgpt.me's production HTML reveals embedded OpenReplay session recording, PostHog analytics, Reddit Ads pixels, and an internal admin menu referencing /admin/chats/ (“Browse and search every conversation”). ExamGhost processes all exam crops in ephemeral RAM with an instant Panic RAM Flush (Esc) and zero chat storage.
How does SnapGPT's 2026 pricing compare to ExamGhost?
SnapGPT's Free plan is capped at 5 screenshot answers per day (with AI chat, explanations, and Autopilot locked). SnapGPT Plus costs $7.99/week (~$34.60/month), $9.99/month, or $89.99/year. ExamGhost gives you 50 Free Solves ($0) (including full Focus Shield + 10 Snap-It OCR snips), a $19/month pass, a $99/year Academic Year Pass ($8.25/mo), or a $199 one-time Lifetime Degree Pass.
