About LLM Guard

LLM Guard helps you use ChatGPT, Claude, Gemini, and other AI tools safely by detecting and blocking sensitive information before it’s sent. This is a no-bullsh*t, open source, privacy first extension that does one simple job with minimal performance impact. All it does is prevent certain types of data from being sent to LLMs, thats it. You can configure rules, regex patterns, or use the presets available in the app. No data gets sent anywhere, no data gets stored, just plain and simple client-side detection and prevention.
