PII ShieldCaviard is a low-cost Chrome extension for one person, masking personal data in ChatGPT and DeepSeek entirely on the device.

Choose Caviard for personal ChatGPT use on a tight budget. Choose PII Shield when staff use several AI tools with customer, candidate or employee data.

When Caviard is the better choice
You are one person using ChatGPT, you want something free or very cheap, and you do not need Claude, Gemini or Copilot covered.
When PII Shield is the better choice
- Your team uses several AI tools. One extension covers ChatGPT, Claude, Gemini, Copilot and more, and one coverage setting drives every surface.
- You need the answer to come back with the real names in it. PII Shield restores each value in the reply, so a drafted email or summary is ready to use.
- You connect internal systems or code to AI. The API gateway, MCP server and Claude connector mask records before the model sees them.
- You want to try it today. The price is on the website and the 7-day trial needs no card and no sales call.
