On-device browser tool that redacts sensitive personal data from prompts before they are submitted to AI tools like ChatGPT or Claude.
LogosGuard is a browser-based data redaction layer that detects sensitive information—names, addresses, account numbers, medical details, and personal messages—and replaces them with placeholders like [NAME] or [ACCOUNT] before a prompt is submitted to AI services. Detection and redaction run entirely in the browser; no sensitive data leaves the device. It works with ChatGPT, Claude, and other major AI tools without requiring changes to user workflows. LogosGuard is a product of LogosGuard.
