AI Prompt Firewall

Local-first prompt risk scanner for AI chat inputs.

🛡️ Stop sensitive data before it reaches AI. AI Prompt Firewall scans your ChatGPT, Claude, and Gemini prompts locally in the browser and warns you when you paste risky data like emails, API keys, tokens, session cookies, private keys, database URLs, or customer identifiers. ✨ What it does: • Highlights risky parts of your prompt before you send • Shows a clear shield warning near the AI composer • Runs locally, without a remote scanning service • Works on ChatGPT, Claude, and Gemini • Helps teams avoid accidental prompt leaks Built for support, engineering, operations, and anyone who pastes real work context into AI tools. AI Prompt Firewall is a lightweight safety layer, not a full DLP system.
