A browser extension that detects and blocks other extensions from reading your AI chat sessions in real-time
Malicious Chrome extensions steal ChatGPT, Claude, and DeepSeek conversations from users at scale by silently reading DOM content and exfiltrating session tokens. Existing extension scanners only do pre-install static permission checks and miss behavioral exfiltration once an extension is installed. This tool monitors every installed extension's actual runtime behavior on AI chat pages and alerts or blocks when one attempts to read conversation content, scrape tokens, or send data to suspicious domains.

Gap Assessment
5 tools exist (ExtensionShield, TrustScan, Extension Auditor Pro, SquareX, LayerX Security) but gaps remain: No runtime behavioral monitoring after install; cannot detect extensions that behave normally on non-AI pages but exfiltrate data on ChatGPT or Claude sessions.; Static analysis only; no live behavioral detection; no AI-context-aware monitoring..

Competitive LandscapeFREE
| Product | Does | Missing |
|---|---|---|
| ExtensionShield | Pre-install static risk scoring and permission analysis for Chrome extensions before you install them. | No runtime behavioral monitoring after install; cannot detect extensions that behave normally on non-AI pages but exfiltrate data on ChatGPT or Claude sessions. |
| TrustScan | Permission risk analyzer with PDF report; audits extensions against known risk patterns. | Static analysis only; no live behavioral detection; no AI-context-aware monitoring. |
| Extension Auditor Pro | Community-based early warning when extensions contact suspicious domains; Chrome Web Store integration. | Community signals are lagging (hours to days behind a new attack); no per-session real-time blocking; no specific protection for AI chat context. |
| SquareX | Enterprise-grade browser security extension blocking malicious websites, phishing, and obfuscated malware; raised $20M Series A (SYN Ventures, Peak XV, 2025); includes extension allowlisting. | Enterprise-only product focused on network-level threats and allowlisting; not built for individual users protecting AI chat sessions; no real-time intra-browser extension behavior isolation at the DOM level. |
| LayerX Security | Enterprise browser extension security management and reporting; publishes the industry Extension Security Report; monitors permission scopes across the enterprise fleet. | Enterprise fleet management tool, not a consumer/prosumer privacy guard; no real-time DOM-level interception of extension reads on AI chat pages. |
