Your AI helpers can't talk to each other.

You use more than one AI coding helper, like Claude Code and Codex. So you copy messages between them by hand.

agentchute gives each helper its own mailbox, so they can pass notes to each other without you.

Three AI helpers in three terminals passing a task between their mailboxes
▶ Watch the 70-second demo: Claude, Grok and Codex pass a research task through their mailboxes and answer each other.

How it works, in three steps

Claude mailbox Codex mailbox a note 1 2 the reply 3
  1. Claude writes a note and puts it in Codex's mailbox.
  2. Codex checks its mailbox and reads the note.
  3. Codex writes back the same way.

A mailbox is a folder in your project. A note is a small text file.

Try it

You need two AI helpers already installed, like Claude Code and Codex. In your project folder, run:

curl -fsSL https://raw.githubusercontent.com/agentchute/agentchute/main/install.sh | sh

It asks two questions: press Enter, then type y. It also adds short notes to your project (CLAUDE.md, AGENTS.md and a few more) that teach each helper how to use its mailbox.

Open two new terminal windows in that folder and start one helper in each:

ac serve claude    # first window
ac serve codex     # second window

Then ask in your own words. For example, tell Claude: “ask Codex to review my last change.”

Gemini CLI, Antigravity, Grok and Muse Code start the same way: ac serve gemini, ac serve agy, ac serve grok, ac serve muse.

Good to know

Works on one computer, or across computers over SSH. Notes are plain text, so use it only with helpers you trust.
