Regulatory Landmine
Compliance is Not Negotiable. AI Data Leaks End Careers.
As noted by the FBI, law enforcement and third parties can legally buy harvested data directly from data brokers. If you paste client data into cloud AI, you are committing a compliance violation — even before a breach occurs.
Healthcare • HIPAA
PHI Exposure to AI Models
Sending Protected Health Info to a hosted LLM is a reportable breach. HHS OCR fines reach $1.5M per violation category, per year.

Class-Action Liability
Leaking employee, customer, or financial records via AI prompts triggers devastating class-action exposure and brand collapse.

Unfair Advantages
Built around the way you actually work.
No Clunky Dashboards
Keep Your Workflow
No clunky third-party dashboards. The extension integrates natively into chatgpt.com, gemini.google, and soon: claude.ai — keep using the tools you already love.
No API Token Fees
No API Markups
We don't resell OpenAI APIs. Stop paying ridiculous per-token fees. Flat rate, unlimited local masking — forever.
Zero Cloud Latency
Jet-Speed Inference
Masking happens in milliseconds in your browser's RAM via your browser's local memory. Zero network latency. Zero lag.
Tech-Flex
The Local Intelligence Engine.
A vertical security stack engineered from the silicon up — so privacy isn't a policy, it's physics.
Local ML Engine
In-Browser AI Sandbox
Creates an isolated Shadow DOM vault inside your browser. The AI website (like ChatGPT) cannot see, read, or access this secure workspace while you type.
On-Device SLM
In-Browser Local AI Protector
Powered by highly optimized Small Language Models that understand complex legal and medical context — running on your hardware, never the cloud.
Auto-Wipe
Auto-Wiping Tab Memory
Data lives only in the active tab's RAM. Close the tab, and everything is instantly wiped. No logs. Zero trace.
EVENT BLOCKING
Anti-Keylogger Shield
Host AI sites often use analytics or hidden scripts that track keystrokes. Thanks to our event-blocking architecture, nothing you type inside our secure panel leaks to the main page. While you type, the AI site sees you as completely silent.
Security & Compliance
Engineered for Privacy. Built for Compliance.
Meet the strictest data protection regulations without complex IT setups. Our local-first architecture ensures your sensitive PII and PHI never leave your browser, eliminating server-side vulnerabilities and instantly solving GDPR, CCPA, and HIPAA requirements by design.
GDPR, CCPA & HIPAA Ready
Since your data never leaves your device, you avoid cross-border data transfers and complex Business Associate Agreements.
100% In-Browser Processing
Masking happens entirely within your local environment. We don't route your text through third-party APIs or cloud redactors.
Zero Digital Footprint
The moment you close your tab, your secure session ends and the data is permanently destroyed. No persistent storage, no hidden logs.
No Server-Side Logging
We can't log what we can't see. Our local-first architecture means your raw text is completely invisible to our servers.
Local Tokenization
Client names, SSNs, and addresses are instantly swapped with secure placeholder tags right on your screen before sending.
Zero AI Training Risk
Because ChatGPT only sees anonymized tags, your highly sensitive client data can never be absorbed to train future AI models.
BLIND TRUST VS. PROVABLE PRIVACY
Privacy by Math, Not by a Promise.
Other tools ask you to blindly trust their servers. We take a different approach: we can't leak your data because we never collect it. Masking happens entirely on your device with zero telemetry.
