Frequently Asked Questions

Which API key formats are supported?

We detect keys from OpenAI, Anthropic, Stripe, AWS, GitHub, and more. We also use generic patterns to catch api_key=xxx and similar formats.

What if my API key format is not detected?

You can use the full preset which includes generic patterns for common key formats. For very unusual formats, you can manually replace them.

Are my API keys sent anywhere?

Never. All processing happens in your browser. Check the Network tab in DevTools to verify no data leaves your machine.
