VibeGard

Privacy-focused Chrome extension that automatically masks sensitive data before sending to LLMs

VibeGard — Protect Your Sensitive Data Before It Reaches an AI Every day, developers, professionals, and everyday users accidentally paste passwords, API keys, email addresses, credit card numbers, and personal IDs directly into ChatGPT, Claude, Gemini, and Perplexity. Once it's sent, you can't take it back. VibeGard sits silently in your browser and catches sensitive data before it leaves your hands. --- How It Works VibeGard watches the input box as you type or paste. When it detects something sensitive — an email address, a password, a database connection string, a credit card number — it alerts you instantly and lets you mask it with a single click. The original text is replaced with a safe placeholder (*****) so you can continue your conversation without exposing private information. Everything runs entirely in your browser. No data is ever sent to any server. No account required. --- What It Detects VibeGard covers a wide range of sensitive data types out of the box: • Contact info — emails, phone numbers, physical addresses • Credentials — passwords, usernames, database connection strings • Financial data — credit card numbers (Luhn-validated), IBANs, bank account numbers • Identity documents — SSNs, passport numbers, national IDs, and similar personal identifiers • API & access credentials — API keys, access tokens, session tokens, bearer tokens, and other authentication data • Infrastructure secrets — IP addresses, private keys, database URLs, MAC addresses, and auth headers --- Key Features 🛡️ Live Detection — The shield button lights up as you type, alerting you the moment sensitive data is detected. A badge on the extension icon shows the count at a glance. ⚡ Auto-Mask Mode — Turn on Auto-Mask from the popup and VibeGard will automatically redact sensitive data as you type, with no manual step needed. 🖱️ Right-Click Masking — Select any text on the page, right-click, and mask just the sensitive parts or the entire selection. 🔒 Mask All — One click in the popup to scan and mask every sensitive item across all inputs on the current page. 📴 Per-Site Control — Enable or disable VibeGard independently for supported AI sites. 🏠 Fully Local — All settings, patterns, and state are stored in your browser's local storage. Nothing leaves your device. --- Who It's For - Developers pasting config files, .env contents, or error logs into AI assistants - Security professionals sharing infrastructure details for analysis - Healthcare and finance workers who need to reference case details without exposing real data - Anyone who wants a safety net before hitting Send --- Privacy VibeGard requires no account, collects no analytics, and communicates with no external servers. The only permissions it requests are access to the sites you choose to enable it on and local browser storage for your settings. Your data stays yours.
