SurfShield

SurfShield uses your webcam and AI to detect when someone is looking over your shoulder — and instantly blurs your browser content to protect your privacy. When they look away, your screen returns to normal automatically. Perfect for coffee shops, planes, open offices, coworking spaces — anywhere your screen might be visible to people you don't know. How it works The extension uses your webcam to count people visible in frame AI analyzes each frame and ignores false positives If two or more people are detected, your active browser tab blurs in under 1.5 seconds When you're alone again, the blur clears automatically Privacy first SurfShield never records, stores, or shares webcam frames. Each frame is analyzed in the moment and immediately discarded. We never identify who's in frame — only that more than one person is visible. One subscription, every device Your $1.99/month subscription unlocks SurfShield on the Chrome extension, the Windows desktop app (covers your full screen), and our upcoming mobile apps.
