NewBrain: a model for each kind of work

Claude Code, Codex and Gemini, working side by side on your Mac. Each thread in its own worktree, all of it in one calm, native window.

Free · Apple silicon · macOS 14 or later

A ten-second scripted demo of the ThreadRig window: the main chat asks for the remaining tasks, the Orchestrator opens two threads, the agent checks the dashboard in the browser, tasks tick to done and the answer arrives.

Bring the CLIs you already use. Your sign-ins, your subscriptions.

How it works

From one request to a clean diff.

Four steps, every time. Each one happens in a panel you can watch.

01

Ask once

Describe the outcome in the main chat. ThreadRig splits the work and shows the plan first.

Three threads are starting, each in its own worktree. I’ll verify the period selector in the browser once they report back.

Threads run in parallel

Each thread gets its own worktree and the CLI that suits it. Your checkout stays untouched.

Questions

Before you download.

Short answers to what people ask first. The privacy page lists every network request the app makes.

Is ThreadRig really free?

Yes. The app is free. You use your own Claude Code, Codex or Gemini CLI, so your provider plans and usage stay exactly as they are.

Which CLIs does it work with?

Claude Code, Codex and Gemini CLI. Each thread can use a different one, and Brain lets you pick a default model and effort for each kind of work.

Will agents touch my working copy?

Not while they work. Every thread runs in its own Git worktree. Changes come back through integrate, and conflicting patches are rejected and kept for review.

Does ThreadRig see my code or keys?

Your CLIs talk to their providers with their own local sign-ins. ThreadRig does not store AI API keys and has no analytics or crash-reporting SDK. Every network request the app makes is listed on the privacy page.

What do I need to run it?

A Mac with Apple silicon on macOS 14 or later, and at least one of the supported CLIs installed and signed in.
