AI Shield

About

Prevents accidental data leaks to AI tools. Now supports Custom Domains and Custom Regex Rules.

AI Shield is a "local-first" firewall that sits between your clipboard and AI websites. It automatically detects and masks sensitive data (PII, API keys, private tokens) before you paste them into chat interfaces.

🚀 NEW IN VERSION 1.1:

Universal Support: Now works on ANY website. Add your own custom domains (e.g., internal-ai.company.com, localhost:3000) to the Allow List.

Custom Block Rules: Define your own Regex patterns to block specific internal project codes or proprietary data formats.

Incognito Mode: Toggle "Auto-Clear" to ensure your history is wiped from memory the moment you close the browser.

Dark Mode: A sleek, professional new look that respects your system preferences.

🛡️ KEY FEATURES:

Smart Detection: Pre-configured to block AWS keys, OpenAI keys, Stripe tokens, Email addresses, and SSNs.

Interactive History: View a log of blocked secrets and copy the original text if you truly intended to paste it.

Zero-Latency: The extension sleeps on non-whitelisted sites to ensure zero impact on your browsing performance.

100% Local & Private: No data ever leaves your browser. All processing happens on your device.

Perfect for: Everyone who uses public or private LLMs—from developers protecting keys to general users protecting their identity.
