AI Chat Shield scans your installed Chrome extensions and monitors their real-time behavior on AI chat sites. Find out what's watching before it steals your data.
In the last 90 days, researchers discovered multiple Chrome extensions, some with Google's "Featured" badge, silently harvesting AI chat data from millions of users.
A "Featured" Chrome extension with a 4.7-star rating was silently capturing conversations from ChatGPT, Claude, Gemini, and 5 other platforms, selling them to data brokers.
Two extensions impersonating legitimate AI tools collected complete ChatGPT and DeepSeek conversation histories, browsing data, and authentication tokens.
Microsoft's own security team published research on extensions designed to passively collect AI-assisted chat content and browsing activity.
Most malicious extensions look clean on permissions alone. They activate harvesting code only when they detect an AI platform in your active tab. That's why AI Chat Shield does both.
Analyzes every installed extension's declared permissions to identify which ones could intercept your AI conversations.
Watches what extensions actually do when you're on AI chat sites, catching the ones that only activate on AI platforms.
"Permission scanning is checking who has a key to your house.
Behavior monitoring is watching if they go through your drawers."
AI Chat Shield runs entirely locally. No servers, no accounts, no telemetry. We built a security tool, not a data collection tool.
All scanning and monitoring happens in your browser. Zero data transmitted.
Install and scan. No signup, no email, no personal information.
No analytics, no tracking, no usage data. We don't know who you are.
Only requests what's needed. Inspect our extension yourself. We encourage it.
