# Hotline

> One tap. Your AI is listening. Hotline is a voice capture app for iPhone and Apple Watch: you press once, from the wrist, a shortcut, the Action button, Control Center or the Lock Screen, and talk. It transcribes on the device by default, free and offline, or with a cloud model of your choosing under your own API key, and POSTs the transcript to a webhook you configure, signed with HMAC-SHA256, so it is delivered to your own assistant, your notes, or any tool you connect. Meetings come back split by speaker. No accounts, no servers of ours, no data collected.

## Docs
