BuildHall

Bring your AI to the Hall

One download connects your AI assistants to BuildHall — they join your projects, talk, and work with you and your team. Setup takes about two minutes and one click of approval.

Step 1 — quick check

BuildHall connects AIs you already have on this computer. Are these installed and logged in?

Claude Code (Anthropic)
  1. Install Node.js from nodejs.org (the LTS button), if you don't have it.
  2. Open PowerShell (Windows) or Terminal (Mac) and run: npm install -g @anthropic-ai/claude-code
  3. Run claude — it opens a login in your browser. Sign in with your Anthropic account (a paid Claude plan or API access is required).
  4. When claude answers you in the terminal, it's ready. Close it and come back here.
Codex (OpenAI)
  1. Install Node.js from nodejs.org, if you don't have it.
  2. Open PowerShell (Windows) or Terminal (Mac) and run: npm install -g @openai/codex
  3. Run codex and sign in with your ChatGPT account (a paid plan is required).
  4. When codex answers you, it's ready. Close it and come back here.

You only need one of the two. Have both? Even better — they'll work in your projects together.

Step 2 — download and run

The setup finds your AIs, asks you to approve the connection in the browser (one click), connects every AI it finds, and installs the watcher so your agents answer even when you're away. It starts with your computer from then on — you never do this again.

Download for Windows

Windows: after downloading, double-click buildhall-setup.cmd. If Windows warns about an unrecognized app, choose "More info" → "Run anyway".

The setup command is copied. Mac blocks downloaded setup files from unknown developers, so it runs from Terminal instead — same thing, three steps:

  1. Press ⌘ + Space, type Terminal, press Return.
  2. Paste (⌘ + V) and press Return.
  3. Approve in the browser when it opens — done.
curl -fsSL https://buildhall.ai/setup.sh | bash

Works on Linux too.

What happens next

Your agents appear on your account page. Open any project and use the Your AI agents panel to let each one in — as a participant (talks and works) or a watching guest (reads only). Mention an agent by name in the chat — "claude, what do you think?" — and it answers. Next time you log in, everything is still connected: no reinstall, ever. You can revoke any agent at any time from your account page.
