A desktop app for Claude Code that walks you through everything Claude changed, out loud. It is in beta, it is free, and it runs on the Claude Code login you already have.

The builds

Apple silicon is out now, because that is where Codeio is built. Nothing in it is Mac-only, so the rest is packaging work rather than a rewrite.

No installer script, no Homebrew, no models to download. About 367 MB of that download is the two voice models, already inside the app when you open it — which is why it is large and why it works offline the first time you press play. The Claude Code CLI is in there too.

What “beta” means here

It will have bugs
It is version 0.1.48. Crash reports are on by default so they get fixed — faults only, never your code or conversations — and you can turn them off in Settings. Details.
The voice takes ~800 ms to start
That is as fast as the voice model goes. You pay it once per turn, while Claude is already thinking.
Updates tell you, they don’t install
Codeio checks for new versions and says so in Settings → About, but it cannot replace itself — macOS does not let an unsigned app do that. Updating is this page again: press Download, and what changed is in Settings → About when you open it.
Some things are missing on purpose
The microphone is push-to-talk only — it never listens on its own, and you cannot interrupt by talking over it. There is no undo history, no debugger or editor extensions, and Claude Code is the only agent.
Your code still goes to Anthropic
Only the voice is local. Claude Code is still the agent, so your prompts and the files it reads are sent to Anthropic, exactly as they are when you run claude yourself. Full details.

Three steps, about a minute.

Codeio does not have an Apple signature yet, so macOS quarantines it on the way in. One command undoes that, for this app only.

  1. Open the .dmg and drag Codeio to Applications

    The usual thing. Then eject the disk image.

  2. Then run this once, after you drag Codeio to Applications

    Paste it into Terminal, press return. Skip it and macOS says “Codeio is damaged and can’t be opened” — it is not damaged, and the download is not corrupt; that is just the message for an app without a signature.

  3. Open it

    Sign in to Claude from the welcome screen and you are working. If you already use the claude command, it picks up that login and there is nothing to paste.

Two kinds of file. Take the one your system installs.

A .deb for Ubuntu, Debian and the systems built on them, and an AppImage for everything else. Each comes for Intel and AMD machines and for ARM ones. This is version 0.1.48.

  1. Ubuntu, Debian, Mint or Pop!_OS: the .deb

    Download it, then run this in the folder it landed in — usually Downloads. apt asks for your password once. On Ubuntu 24.04 and newer, this is the one to take.

    Intel / AMD 623 MB ARM 499 MB

  2. Anything else: the AppImage

    Make it runnable, then open it from your file manager or the terminal. It updates itself when a new version is out.

    Intel / AMD 754 MB ARM 566 MB

  3. Open it

    Sign in from the welcome screen and you are working. If a coding agent’s command already runs in your terminal, Codeio finds it and signs in through it.

Three steps, and one warning.

For Intel and AMD machines running Windows 10 or 11. Codeio is not signed with a certificate yet, so the first run is met by a warning — step two is the way past it.

  1. Run the installer

    It installs for you alone, so it never asks for an administrator password, and it opens when it finishes.

  2. “Windows protected your PC”

    Press More info, then Run anyway. Windows says this about any app whose publisher it does not recognise, and Codeio is not signed with a certificate yet — the same reason the Mac download needs a command. You see it once; updates from inside the app never ask again.

  3. Sign in and you are working

    The welcome screen signs you in. If a coding agent’s command already runs in your terminal, Codeio finds it and uses that. Git for Windows is worth having — Codeio leans on git for everything it shows you about your changes.
