What LogosGuard does
LogosGuard is risk management software for organizations adopting AI, with a focus on preventing sensitive data from leaking into AI tools. Its browser extension automatically detects and redacts personal and confidential information in prompts before they are sent to AI assistants, addressing the reality that most such leaks are accidental.
Key capabilities
The extension identifies sensitive data such as names, addresses, account numbers, and medical details, replacing them with placeholders like [NAME] and [ACCOUNT] before submission. It integrates with major AI platforms including ChatGPT, Claude, Perplexity, Copilot, and Gemini, and operates entirely on the user's device with no data sent to external servers and no account required.
Who it's for
LogosGuard is aimed at enterprises and professionals who regularly use AI tools and need an automated safeguard against accidental data exposure when drafting messages, debugging code, or running everyday queries. It is backed by Y Combinator.
