Clack – AI Agent Messenger

Your Claude Code sessions, in your pocket. Speak, listen, and keep the work moving while you're away from your desk — screen off, AirPods in.

Clack is a Voice Messenger made for Claude Code. Connect and control your sessions on Mac, from your iPhone — with the screen off, just by talking.

You already have Claude Code sessions running on your Mac. Clack lets you listen in on them from anywhere else, and drive them forward by talking.

Not a chatbot, and not a second Claude. The same sessions you left open, in your pocket — you hear what they're doing and you answer, and the work carries on where it was.

HOW IT FEELS

Put your AirPods in and leave the house. Clack reads out what your session is doing, in the words it would have written on screen. You say what you want next. It goes and does it, and tells you how it went.

• Hear the reasoning as it happens — not a log of every step • Say something the moment you want to change direction • Screen off, phone in your pocket, hands doing something else • Every session on your computer, switched between by voice

YOUR COMPUTER, YOUR SESSIONS

Clack talks to a small relay you install on your own machine, alongside Claude Code. There is no server of ours in between holding your work.

• The relay runs on your computer — you install it, you control it • Your phone and computer meet over your own Tailscale network • Messages are end-to-end encrypted, with a key only your two devices have • No account, no sign-up, no inbox of your conversations anywhere

We can't read your sessions, because they never reach us. Speech is the one exception and it is explained plainly in the app before you agree to anything: what you say is transcribed, and replies are voiced, by a speech service — the audio, and nothing else.

WHAT YOU NEED

• A computer running Claude Code, with the free Clack Relay app on it • Tailscale on both devices — free for personal use • About five minutes to pair them, once

REQUIRES A SUBSCRIPTION

Clack is €4.99 a month with a one-week free trial. The subscription covers the speech that makes it hands-free. Cancel any time in Settings.
