Speak commands and watch them execute instantly. Not just transcription - true voice-to-action that lets you code, debug, and manage projects while completely hands-free.
How does it work?
Start Happy CLI and you'll have a regular Claude Code session. But you can continue that same session from
iOS,
or Web
Happy has three parts that work together:
CLI Program (happy)
└─
This runs on your computer. It starts Claude Code and watches what it does. Then it encrypts this information and sends it to a server.
Mobile App
└─
This runs on your phone. It gets the encrypted data from the server and shows you what Claude Code is doing. All the display code lives here.
Relay Server
└─
This connects your computer and phone. It passes encrypted messages between them. The server can't read your data. It just moves encrypted blobs around.
