Cloakworks by MugatuAI - AI Privacy Shield

Never paste a secret into ChatGPT again. Cloakworks intercepts and scrubs data leaks locally before prompts 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: What’s New in v3.1.5: • Full Microsoft Copilot & Microsoft Web Protection: Real-time pre-flight scanning and one-click in-place scrubbing across ChatGPT, Claude, Gemini, Perplexity, and Grok. • Healthcare & EHR Clinical Context Preservation (HIPAA Safe Harbor): Automatically replaces Epic/Cerner Medical Record Numbers (MRNs), Contact Serial Numbers (CSNs), Physician NPIs, patient names, and calendar dates with deterministic surrogates ([PATIENT_A], [CLINICIAN_1], [MRN_1], [DATE_INDEX_0]) so clinical timelines stay intact without exposing PHI to external AI models or vector databases. • Adversarial Prompt Injection & Jailbreak Guardrails: Blocks "Do Anything Now" (DAN) patterns, system prompt extraction directives, delimiter hijacking, and Base64/ROT13 obfuscated payloads before transmission. • Dual-Track Enterprise Model Routing: Enforces strict zero-trust sanitization on public multi-tenant frontier models while allowing configurable pass-through policies for sanctioned internal open-source models and private VPC endpoints. • Traceable Enterprise SIEM/SOAR Telemetry: Supports real-time masked incident alerts for Microsoft Sentinel, Splunk, Microsoft Teams, and Slack.
