What is LogosGuard
LogosGuard is the sensitive data redaction layer for AI: it redacts sensitive data before prompts leave the device. Since AI is too useful to avoid and the question is what gets pasted into it, LogosGuard replaces sensitive data like names, addresses and account numbers with placeholders — only the user sees the real values — and a toggle switches back and forth to see exactly what was sent to the AI models. Detection and redaction happen locally in the browser, so no sensitive data leaves the device. The extension is developed by Stanford researchers and engineers, and more information is at logosguard.com.

Your sensitive data, like names, addresses, and account numbers, get replaced with placeholders. Only you see the real values. Toggle back and forth to see what was sent to the AI models.
