AI Privacy Gateway — Install a Firewall for Your AI Data in 30 Seconds

Your prompts are leaking PII to AI APIs right now. Here is how to stop it.

The Wake-Up Call

Every time you paste code into Cursor, Claude Code, or ChatGPT, you might be sending phone numbers, API keys, emails, and ID cards to third-party servers. Your AI coding assistant does not know the difference between code and secrets — it sends everything.

AI Privacy Gateway sits between your AI client and the API, detecting and masking sensitive data BEFORE it leaves your machine.

How It Works

Your AI Client → [Privacy Gateway :9999] → Masked Data → OpenAI/DeepSeek/Anthropic
                     ↓
              Local Encrypted Vault

Intercept AI API requests in real-time (< 1ms latency)
Detect 14+ PII types + 20+ API key formats
Replace with typed placeholders: [PHONE_abc], [EMAIL_xyz]
Forward masked request — provider NEVER sees raw data

30-Second Setup

docker run -d -p 9999:9999 ghcr.io/gunxueqiu6/ai-privacy-gateway:lite
# Point your AI client to http://localhost:9999 — done.

Works transparently with: Cursor, Claude Code, VS Code, Cody, ChatGPT.
