AI Privacy Shield – Protect Your Sensitive Data in AI Chats
AI Privacy Shield helps keep your personal and sensitive information safe while using AI platforms like ChatGPT.
It automatically detects and masks sensitive data before your message is sent, and restores it locally after the response is generated. Everything happens on your device. No servers involved.
