PISIGuard: Protect your personal and sensitive info when you chat with AI
For engineers who build or use AI chat interfaces, this tool addresses the risk of inadvertently leaking credentials, API keys, or personal data to third-party AI services. It runs entirely locally, so no additional server infrastructure or trust in a middleman is required, making it a practical privacy layer for everyday AI interactions.

PISIGuard masks names, emails, phone numbers, passwords, API keys, and more before the message reaches the AI, and restores them in the reply.
All detection, masking, and restoration happens locally in the browser; no data is sent to an external service beyond the AI platform itself.
The extension works on ChatGPT, Claude, and DeepSeek, and requires minimal permissions with no background processes.
