AI Privacy Guard

About

AI Privacy Guard is a professional-grade, zero-trust browser extension designed to keep your sensitive information private while using web-based AI platforms. It protects your screen from "shoulder surfing" and accidental data leaks during presentations, screen shares, or in public spaces.

✨ CORE FEATURES

🔒 Zero-Trust Privacy
• 100% Local: No data ever leaves your browser. No external API calls, no tracking, and no analytics.
• Deep Scoped: Automatically becomes dormant on non-LLM websites to ensure zero interference with your normal browsing.

🌓 Presentation Mode
• Global Blur: Instantly blur your entire chat history sidebar.
• Hover to Reveal: Need to find a specific chat? Just hover over a blurred item to temporarily peek behind the curtain.
• Selective Keywords: Enter keywords (e.g., budget, project-x, salary) to only blur matching conversations.

🕵️ Automated Secret Redaction
Automatically scans visible text and masks developer secrets, including:
• Cloud Credentials: AWS Access Keys
• Authentication: JWTs, GitHub tokens, Slack tokens
• AI API Keys: OpenAI, Anthropic, Google API keys
• Generic Secrets: PEM private keys, passwords, and tokens

🚀 COMPATIBILITY
Works seamlessly across major AI chat interfaces and web-based LLM environments. AI Privacy Guard dynamically adapts to popular sidebars and input fields to keep your data protected wherever you work.

🛡️ SECURITY FIRST
Built with a strict Content Security Policy (CSP), pure Vanilla JS/CSS (no bloated dependencies), and requires minimal permissions. Processed secrets are masked in the DOM only and are never logged or transmitted.
