GPT Defender

Detect sensitive data in ChatGPT input and request user consent before making corrections.

GPT Defender helps protect your privacy when using GPTs and other LLM tools. The extension monitors prompts in real time and alerts you when sensitive or personally identifiable information (PII) may be exposed. Whether you're drafting emails, documents, or forms, GPT Defender helps you avoid accidentally sharing data such as names, addresses, or identification numbers. There’s no need to send sensitive details just to rephrase or format content — GPT Defender ensures you stay in control of what you share.
