Redact sensitive and personal information while using ChatGPT, Claude, Gemini or DeepSeek.

Caviard is a Chrome extension that automatically redacts sensitive and personal information (PII) before you send prompts to AI services, ensuring privacy without compromising functionality.

Everything runs locally in the browser of your computer, so your prompts never leave your machine.

All data is stored on your computer, without being shared with any AI or other third parties. 100% secure.

🔒 Key Features: ✔ Real-Time Protection: Instantly detects and masks personally identifiable information (PII) before it reaches AI models. ✔ 100% Local Processing: Your prompts and the values Caviard protects never leave your browser. We have no server that sees them. ✔ Seamless Integration: Works directly in ChatGPT, Claude, Gemini and DeepSeek without affecting your experience. ✔ Smart Data Masking: Replaces sensitive details with realistic placeholders while maintaining text flow. Each person keeps their own placeholder, so a prompt about three people still reads as three people. ✔ Add Your Own: Mark any value you want protected, even one Caviard did not flag — names, emails, phone numbers, IBANs, card numbers and more. ✔ One-Click Toggle: Easily switch between masked and original text using a simple keyboard shortcut (Alt+R).
