How to prevent API key leaks in AI tools.

Developers regularly paste logs, configs, or code into AI tools. That creates a real risk of exposing API keys, bearer tokens, client secrets, and other credentials unless prompts are checked before send.

Where API key leaks happen

  • Configuration files pasted into a prompt for debugging.
  • Code snippets containing environment variables or secret literals.
  • Terminal logs or error dumps copied into AI chats in a hurry.

What a browser-side protection layer should detect

  • Common API key prefixes and token formats.
  • Quoted secrets and credential-like variable names.
  • Structured values that often indicate sensitive access credentials.

Why local redaction matters

If the prompt is cleaned in the browser before submission, the raw secret does not need to pass through an extra vendor-controlled relay service first.
