Ghost List: Your First Line of Defense in Prompt Security Ghost List is a lightweight, zero-trust prompt security tool built specifically for Google Chrome and Chrome-compatible browsers (such as Microsoft Edge, Brave, and Opera). Designed to act as an immediate, local firewall for your artificial intelligence interactions, Defensify SCR actively sanitizes your inputs on the web’s most popular AI platforms before your data ever reaches a third-party server. Executive Summary- As generative AI tools become deeply integrated into our daily workflows, the risk of accidental data leakage increases. Sharing internal code names, proprietary metrics, client names, or sensitive personal identifiers with LLMs can compromise compliance and privacy. Ghost List serves as your first line of defense in prompt security, shifting data protection directly to the client side. By intercepting and eliminating blacklisted terms before they are prompted, saved, or transmitted, the extension ensures that sensitive data never leaves your local environment. Core Features & Functionality: 1. Multi-Platform Real-Time Interception- The extension integrates into the web interfaces of leading AI platforms. It continuously scans the active chat compose boxes on exactly three targeted ecosystems: Claude (claude.ai) ChatGPT (chatgpt.com and chat.openai.com) Google Gemini (gemini.google.com) 2. Dual-Layer Scrubbing Mechanism- Ghost List uses a highly responsive, two-stage checking routine to guarantee complete coverage: Real-Time Typing Strip: As you type in the chat input box, the extension evaluates the text dynamically. If a blacklisted term is matched, it is instantly stripped out in real time. Pre-Flight Verification: To account for quick copy-pasting or rapid hitting of the "Enter" key, a final, foolproof check is executed the exact millisecond before the message is finalized and sent. Any remaining matching terms are wiped instantly. 3. Flexible, Granular Filtering Rules- The extension gives users absolute control over their local dictionary. The scrubbing engine is optimized to match and eliminate target terms meeting the following parameters: Length & Structure: Supports terms spanning 1 to 3 words, or distinct groups of letters, numbers, and symbols. Character Limits: Handles precise configurations up to 50 total characters per individual blacklist entry—making it ideal for API keys, telephone numbers, specific account IDs, or proprietary project codenames. Terms are case insensitive. Technical Architecture & Privacy Commitments- Ghost List is built on a strict Zero-Data-Collection framework. Traditional security tools often rely on cloud-based processing to analyze text, creating another vector for potential data breaches. Ghost List handles 100% of its operations locally. No Prompt Logging: The extension never reads, stores, or transmits your prompt history, chat content, or general browsing behavior. Local Storage Isolation: Your personalized list of blacklisted terms is stored entirely within your browser's private storage sandbox (chrome.storage.local). No account creation is required, and your configurations never sync to an external database. No Data Resale or Ads: Ghost List is completely ad-free, tracking-free, and contains zero third-party telemetry scripts. Transparent Licensing & Payment Model- To maintain operational integrity without relying on invasive data monetization, Ghost List utilizes a straightforward, low-cost utility model: 30-Day Free Trial: Enjoy unrestricted access to the extension's full suite of features immediately upon installation. One-Time Lifetime Unlock: After the 30-day trial concludes, prompt screening temporarily pauses. Permanent, lifetime access can be restored via a simple, one-time $1 payment. Secure External Processing: Financial details (including credit card numbers) are never collected, processed, or visible to the extension. All transactions are securely routed through trusted industry leaders, Stripe and PayPal. Anonymized License Checks: License validation relies purely on a randomly generated, non-personal installation ID via an automated, low-overhead background alarm checking system. Installation & System Requirements- Supported Browsers: Google Chrome, Brave, Microsoft Edge, Opera, Vivaldi, and other Chromium-based environments. Permissions Required: Minimal footprint (storage for local settings, alarms for background license validation, and targeted host_permissions exclusively for the supported AI URLs and the verification gateway).
