About PrivacyGuard LLM
🛡️ PrivacyGuard LLM: Your Ultimate AI Privacy Shield
Why do you need PrivacyGuard LLM?
When interacting with AI models like ChatGPT, Claude, or Gemini, we often unintentionally paste text containing sensitive information. Whether it is API keys in code snippets, server credentials in server logs, or home addresses in resumes—once you click "Send," that data is on the cloud and could potentially be used for model training.
PrivacyGuard LLM is built to be your first line of defense. It is a lightweight, intelligent, and completely localized extension that redacts your sensitive data before it ever leaves your browser.
🌟 Key Use Cases
1. Automatic De-identification The moment you paste text, PrivacyGuard uses 20+ specialized regex engines to scan and replace sensitive data types—including names, emails, credit cards, file paths, and IT system logs—in real-time.
2. A Must-Have for Developers & DevOps Optimized specifically for IT troubleshooting. It automatically identifies and redacts passwords in Linux commands (e.g., sshpass), credentials in SQL scripts, system UUIDs, and internal IPs, allowing you to debug with AI without compromising infrastructure security.
3. Enterprise-Grade Customization Define your own "Blacklist" keywords. Whether it's a secret project name or a private codename, once configured, PrivacyGuard will ensure it never gets shared with an LLM.
