Run a Jarvis on Your Own Claude Code: The Free Voice Assistant That Needs No API Key
Say "Hey Jarvis" and a voice assistant wakes up in your browser, powered by the Claude Code you already pay for. No API key, no cloud bill. A free open-source repo, how to install it in four commands, and the safety switch you should know about before you let it act for you
Every voice assistant you've tried either does very little or costs a monthly fee on top of what you already pay. This one runs on the Claude Code subscription you already have.
It's called Jarvis. It's free, open source (MIT), and you wake it by saying its name.
What you need
- A Claude Code subscription. The repo says it's the only subscription you need: no API keys and no cloud bill.
- Node 20 or newer.
- Chrome or Edge in a real window, because it listens through the browser.
