Description
Mask sensitive data and PII before chatting with AI. Enjoy 100% on-device processing and provable-trust security. Do not compromise client, patient, or enterprise data when using ChatGPT and Gemini. MaskPrompt is an end-to-end security shield that masks your sensitive data entirely locally within your browser. Guarantee compliance with HIPAA, GDPR, and ABA Rule 1.6 without changing your daily workflow. Why Choose MaskPrompt? - Zero Data Leakage: Your text and documents never travel to an external masking server; all processing occurs strictly within your local RAM. - Native Integration: There is no need to switch to a clunky, third-party web dashboard. MaskPrompt integrates directly into standard AI interfaces (e.g., chatgpt.com) as a secure, isolated workspace. - Zero API Costs: Unlike cloud-based security tools, you do not pay extra fees per word or per token. - Multi-Format Support: Parses and masks lengthy Microsoft Word (.docx) contracts and documents locally within the browser environment. - Human-Error Shield (Shadow IT): Fundamentally prevents internal teams from accidentally pasting confidential company secrets or Personally Identifiable Information (PII) into public AI models. How It Works (End-to-End Masking Cycle) 1. Local Detection (In Milliseconds): The moment you type a prompt, our integrated Small Language Models (SLMs) execute directly on your device to instantly detect sensitive data such as Names, Social Security Numbers (SSNs), and financial records. 2. Smart Tokenization: Milliseconds before your data touches the internet, sensitive information is replaced with secure cryptographic tags (e.g., <FIRST_NAME_E6F6/> or <CREDIT_CARD_DBBA/>). Only these anonymized reference codes are transmitted to the target AI platform. 3. Seamless Unmasking: Responses generated by ChatGPT or Gemini are intercepted by MaskPrompt right before they are rendered on your screen. The secure tags are locally translated back to their original words, ensuring a completely natural and fluent reading experience. Enterprise Architecture & Compliance (Privacy by Math) - Auto-Wiping Tab Memory: Mapping dictionaries and original data are never written to your device's hard drive. They are held temporarily in the volatile memory of the active tab. The exact moment the relevant AI tab is closed, all data is permanently erased from the operating system, leaving no digital footprint. - Zero-Server Infrastructure: We do not log data and cannot share it. Instead of relying on a "Privacy by Promise" policy, the system is built on "Privacy by Math"—a technical architecture that makes server-side data interception physically impossible. - Strict Regulatory Compliance: Eliminates the risk of data breaches, legal penalties, and license revocations for professionals operating within the legal, healthcare, and financial sectors. Setup and Performance Installation requires no complex API keys or IT department intervention. The extension can be installed in seconds, immediately activating the secure interface. Because the system utilizes task-specific micro-intelligence engines rather than resource-heavy, billion-parameter models, it operates with zero latency, does not slow down your hardware, and has zero impact on battery life.
