ChatDataMask: ChatGPT & Claude Incognito Mode. Prevent AI Leaks (GDPR)

Description

Support your GDPR & EU AI Act workflow: mask names, emails, and phone numbers locally before sending prompts to ChatGPT or Claude. ChatDataMask is a lightweight Chrome extension designed to support your GDPR & EU AI Act workflow by helping professionals mask and redact PII — names, emails, and phone numbers — locally before sending prompts to ChatGPT or Claude. This privacy tool serves professional users, HR teams, recruiters, lawyers, copywriters, and analysts who want to leverage the power of Artificial Intelligence while taking steps to mitigate data leaks or regulatory non-compliance. 🔒 LOCAL-FIRST ARCHITECTURE The extension acts as a local layer where text obfuscation, prompt anonymization, and token restoration are processed inside your browser (Side Panel). Your identifiable records (PII) are handled on your device, reducing exposure to external servers or AI training pipelines. 💡 PURPOSE OF THE TOOL Every time you paste client contracts, CVs, financial reports, or corporate messages into cloud-based AI systems, you risk exposing confidential information. This extension acts as a secure local barrier between your private inputs and public cloud models. 🛠️ MASKING CAPABILITIES The system is built to detect, redact, and obfuscate common sensitive data categories, including: - Contact Details (email addresses, usernames) - Phone Numbers (powered by 'libphonenumber-js' for global formats) - Financial Information (IBAN, SWIFT codes, account numbers) - Card Numbers (common credit card formats) - Crypto Assets (wallet addresses for Bitcoin, Ethereum, etc.) - Technical Identifiers (IP addresses, MAC addresses, URLs) - Personal Identifiers (names, passport numbers, national ID numbers, tax identification numbers) 🚀 HOW IT WORKS - Safe Prompting: Send anonymized prompts to AI platforms while keeping the text context readable for the model. - One-Click Restoration: Reverse the AI's response back to your original data, right inside your workflow. - Automatic Reset on Edit: Changing your input automatically clears any downstream response and result, so you never mix up old and new data by mistake. - Guided Step Flow: The extension only lets you move forward when the current step's data is ready, reducing manual mistakes during processing. 🎯 WORKS ALONGSIDE Optimized to work alongside public AI web interfaces including ChatGPT (OpenAI), Claude (Anthropic), Google Gemini, and Microsoft Copilot.
