ChatWall - Anonymise & Mask Private Data for AI — StarObject

Secure your AI prompts and maintain digital sovereignty. Mask and anonymise sensitive private data locally on your device before sending it to ChatGPT, Gemini, or other LLMs.

ChatWall is a privacy extension that ensures 100% local processing. We prevent private data leaks and ensure GDPR compliance through real-time anonymisation of PII (Personally Identifiable Information).
Key Advantages:
🛡️ Client-Side Masking: Your data is masked locally on your device. Sensitive data never leaves your browser.
🔓 Smart Unmasking: Seamlessly restores original data in AI responses, so your workflow remains uninterrupted.
📂 Open Source: Our code is public and audit-ready. Trust is earned through transparency—you can verify exactly how your data is handled.
🔒 Real-Time Protection: Instantly detects names, emails, phones, credit cards, and other private data as you type.
✅ Works with major AI websites: Including ChatGPT, Gemini, and many others ...
💼 Enterprise-Grade Security: Designed for professionals and teams who need to ensure GDPR/CCPA compliance while leveraging the power of modern AI.

How it works:
🔒 Masking: You type "john@doe.com" ChatWall detects an email and sends "[EMAIL_1]" to the AI.
🔓 Unmasking: When the AI replies " [EMAIL_1]", ChatWall automatically restores it to "john@doe.com" on your screen.
You work naturally with your real data, but the AI provider only ever sees the anonymous tokens.
