⁠CodeMask Web UI

A browser-based privacy tool for safely sharing code, configuration files, and logs with AI assistants.

CodeMask detects sensitive values and replaces them with reversible placeholders before you copy content into ChatGPT, Claude, Gemini, or another AI assistant. When you receive the AI response, paste it back into CodeMask to restore the original values locally.

Everything runs in the browser.

⁠How It Works

Paste code or configuration
      ↓
CodeMask detects sensitive values
      ↓
Sanitize and copy
      ↓
Share sanitized content with AI
      ↓
Paste the AI response back
      ↓
Restore original values locally

Example:

10.20.30.40 → {{IP_1}}

Send the sanitized content to the AI.

If the AI responds with:

Connect to {{IP_1}}

CodeMask restores it locally:

Connect to 10.20.30.40
