Optional add your key and setup wallet connect (scan a QR code in Amethyst) for zapping within Amethyst.

So it’s a browser extension for a desktop / laptop?
Yes but once you setup wallet connect you can zap with it from Amethyst on Android or other apps that support it without leaving the app.
You can zap as fast as you can click. I think Vitor posted a video of it in action.
You can also add the lightning address to your profile to receive zaps like you do with WOS.
