GuardGPT

Guard GPT – Redact Sensitive Data Before It Reaches ChatGPT Protect PHI and sensitive information automatically. Guard GPT is a privacy-focused Chrome extension that sits between your browser and ChatGPT, preventing protected health information (PHI) or other sensitive data from ever leaving your environment. Powered by internally hosted redactation software and encrypted storage, Guard GPT filters out PHI and confidential data in real time before it ever leaves your browser session. The redacted message is securely transmitted to ChatGPT, while the original version remains encrypted for up to 24 hours for user retrieval and is then permanently destroyed. Guard GPT helps professionals safely use AI without risking data exposure. Whether you work in healthcare, legal, or any field handling confidential information, Guard GPT adds a critical privacy layer to your ChatGPT workflow. Key Features: • Real-time detection and redaction of PHI and sensitive data • 96% redaction accuracy using in-house technology • Secure, self-hosted infrastructure (no third-party data sharing) • Simple browser integration — works directly with ChatGPT • Managed billing and subscription through Stripe (cancel anytime)
