ChatWall - Anonymise & Mask Private Data (PII) in AI LLM prompts : ChatGPT…

ChatWall - The Ultimate AI Privacy Firewall & Anonymiser 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 (Natural Language Processing + Local AI Privacy Filter model). We prevent private data leaks and ensure GDPR compliance through real-time anonymisation of PII (Personally Identifiable Information). Key Advantages: 🛡️ 100% Local Masking: Your data is masked and anonymised locally on your device. Private data never leaves your browser unmasked. 🔄 Smart Unmasking: Seamlessly restores original data in AI responses. Your workflow remains uninterrupted while the LLM works on anonymous tokens. 📂 Transparent Code (Source Available): Our code is public and audit-ready on GitHub. Trust is earned through transparency—verify exactly how your privacy is handled. 🚀 Real-Time PII Protection: Instantly detects and masks names, emails, phones, credit cards, and other private data as you type. 🌐 Works with Major LLMs: Compatible with ChatGPT, Google Gemini,.. and many others. 💼 Enterprise-Grade Security: Designed for professionals who need to ensure GDPR 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. ✅ Why trust ChatWall? 💻 Local-First Architecture: ChatWall is built so your data never leaves your device. All masking and anonymising processes happen strictly within your browser. 🛡️ Securely Isolated Overlay: ChatWall runs in a separate protected layer on top of the website. Because it is technically isolated, the host website's code (JavaScript) cannot see, access, or read anything you type inside the ChatWall window. 🔍 Total Transparency: We are "Source Available". You or your security team can audit our code to guarantee that your private data remains truly private.
