Keystone Privacy Shield 제작자: karan

eystone Privacy Shield protects your sensitive data when using AI tools. It works as a local privacy layer between you and cloud AI services — all processing happens on your machine.

Features:
- Automatic PII detection (names, emails, phone numbers, addresses, and more)
- Real-time highlighting of detected entities while you type
- One-click redaction before sending to AI
- Smart restoration with interactive badges in AI responses
- Right-click context menu for manual redaction
- Per-site safe lists — mark words as safe so they're never redacted
- Zero-knowledge architecture — your data never leaves your machine

How it works:
1. Type a message in ChatGPT, Claude, Gemini, or Perplexity
2. Keystone detects personal information automatically
3. PII is replaced with safe placeholders before sending
4. When the AI responds, Keystone restores your real data locally

Requires the Keystone desktop application running locally for PII detection.
