Zero-knowledge privacy for AI chats. Redacts PII before it reaches ChatGPT, Claude, or any LLM.
简介
Keystone Privacy Shield is a zero-knowledge privacy layer for AI chats. It automatically detects and redacts personal data before it reaches ChatGPT, Claude, Gemini, or any AI service — then restores it when the response comes back. All
processing happens locally on your device.
HOW IT WORKS
1. Type a message in any supported AI chat
2. Keystone detects personal information (names, emails, phone numbers, addresses)
3. PII is replaced with safe placeholders before sending
4. The AI never sees your real data
5. When the AI responds, Keystone restores your original data locally
FEATURES
• Automatic PII detection — names, emails, phone numbers, IBANs, tax IDs, and more
• Real-time highlighting — see detected entities as you type
• Smart restoration — interactive badges show what was protected
• Right-click redaction — manually redact or mark text as safe
• Entity type control — choose exactly which data types to protect
• Per-site settings — enable or disable on specific websites
• Thorough Mode — deep AI-powered scan for maximum detection
• Zero-knowledge architecture — your data never leaves your machine
SUPPORTED SITES
• ChatGPT (chatgpt.com)
• Claude (claude.ai)
• Google Gemini (gemini.google.com)
• Perplexity (perplexity.ai)
REQUIRES
Keystone desktop application running locally for PII detection. The extension communicates only with localhost — no external servers.
PRIVACY
All processing is local. No data is collected, transmitted, or stored by Keystone. Your personal information never leaves your device.
