About AI Security Shield
AI Security Shield helps reduce accidental exposure of sensitive data when using AI chatbot platforms.
WHAT IT DOES
Every day, people paste contracts, emails, and documents into AI chatbots — often containing personal names, email addresses, phone numbers, bank details, tax IDs, and passwords. AI Security Shield detects and replaces this information with anonymous tokens before it ever leaves your browser. The AI gets the context it needs; your private data stays on your device.
HOW IT WORKS
1. Install the extension
2. Open a supported AI chatbot platform
3. Type or paste your text normally
4. The extension detects and tokenizes sensitive data in real time
5. The AI only sees anonymous tokens like [PERSON_1], [EMAIL_1], [IBAN_1]
6. Use Reveal Mode (Alt+R) to restore original data in AI responses

The extension detects and masks various types of sensitive data including: passwords, API keys, email addresses, phone numbers, IBAN and credit card numbers, tax IDs, personal and company names, physical addresses, and more.
