Mugatu Signal™ - AI Protector

Intercepts and scrubs data leaks locally inside Gemini, ChatGPT, Claude, and ChatHub before they reach public clouds.

Protect your intellectual property, client accounting records, and confidential data within "the four corners of your wall." Mugatu Signal is a local-first browser guard designed for professionals, engineers, and enterprise users working with web-based AI tools. FEATURES: • Real-Time Prompt Interception: Inspects prompt submissions across major enterprise AI interfaces—including Google Gemini, OpenAI ChatGPT, Anthropic Claude, Microsoft Copilot, and custom web LLM endpoints—when Enter is pressed or Send is clicked. • Local Privacy Shield: Evaluates prompt text directly in your browser against comprehensive data leak patterns (credit card numbers, personal contact details, API keys, internal source code, and corporate identifiers). • Interactive Redaction Gatekeeper: Opens a clean on-screen dialog when sensitive data is detected, allowing you to redact/mask variables before outgoing transmission or allow explicit user override. • Optional Desktop Integration: Seamlessly connects with the local Mugatu Signal desktop companion app (running on localhost:8000) for cross-platform audit logging and organization security logs. Operates fully standalone in the browser when offline. -------------------------------------------------- HOW TO TEST & VERIFY PROTECTION: -------------------------------------------------- Once installed, verify real-time interception in three easy steps: 1. Open Google Gemini (gemini.google.com) or ChatGPT (chatgpt.com). 2. Type a test prompt containing mock sensitive data: "Please charge my corporate card 4111-2222-3333-4444" 3. Press Enter or click Send. 4. The extension halts the submission and displays the interactive Mugatu Gatekeeper modal. 5. Click "Mask & Send" to automatically redact the financial string to [REDACTED FINANCIAL] before it leaves your machine! -------------------------------------------------- SUPPORT & PRIVACY: • Support Website: https://mugatuai-helpdesk.lovable.app • Privacy Policy: https://signal.mugatuai.com/privacy • Contact: support@mugatuai.com
