Live-DOM Reversible AI Sanitizer

Masks secrets, emails and databases before they reach the AI, and restores them live on screen as it replies. 100% local.

A Chrome (Manifest V3) extension that keeps secrets out of AI chats without breaking the conversation. Going in: When you paste code, logs, or configs into ChatGPT, Claude, or Gemini, API keys, emails, database names, and similar sensitive values are swapped for structurally similar placeholders (e.g., acme_prod_db → MOCK_DB_01) before the text reaches the input box. Coming out: As the AI streams its reply, the extension swaps the placeholders back to your real values on your screen. The AI model never knows your secrets, but the conversation flows naturally. "Copy code" and Ctrl+C also hand you the fully restored text. Completely Local: Everything operates locally in the browser tab's memory. There are no servers, no network requests, no background workers, and no telemetry.
