PrivacyShield

Use AI Fearlessly — detect and mask PII before sending to AI chatbots

- USE AI FEARLESSLY PrivacyShield automatically detects personal information — names, addresses, phone numbers, credit cards, SSNs, API keys, and more — as you type into ChatGPT, Claude, and other AI chatbots. Before your message is sent, PrivacyShield masks sensitive data with safe placeholders like [PERSON_A]. The AI gets your question without your real data. When the AI responds, PrivacyShield unmasks the placeholders so you see your information back — seamlessly. - HOW IT WORKS 1. Type normally into ChatGPT or Claude 2. PrivacyShield highlights detected personal data in real-time 3. Before sending, choose what to mask in a simple confirmation dialog 4. Critical data (credit cards, SSNs, API keys) is auto-protected 5.
