getting started
Up and running in a few minutes.
Brett is a coding agent that lives in your terminal and picks the right model for every task automatically. Here's everything you need to start.
Install Brett
You'll need Node.js 18 or newer. Then install from npm:
Don't have Node? Install it first — winget install OpenJS.NodeJS on Windows, or grab it from nodejs.org. Reopen your terminal afterward.
Windows users — one extra step
Windows blocks npm scripts by default. Run this once in your PowerShell session before installing:
Create your account
Sign up on the dashboard. Your team and workspace are created automatically.
Sign up →New accounts start empty. Once you've signed up, send us your account email and we'll add starting credits so you can begin right away.
Log in from the terminal
Use the same email and password you just signed up with:
Your login is saved, so you only do this once per machine.
Start building
Go to any project folder and launch Brett:
Just type what you want in plain English. Brett reads your code, proposes changes as diffs you approve with y, and runs commands when you let it.
A few things to know
You never pick a model
Brett routes each task to the right tier automatically — cheap and fast for routine work, stronger models for hard problems. For a genuinely tough task, type /max to force the most capable model.
Mention files with @
Type @src/auth.ts to pull a file into the conversation so Brett can see it.
Plan before building
Type /plan and Brett asks questions to scope a feature before writing code. /build hands the plan to the coder.
Track spend on the dashboard
The usage pageshows exactly what you've spent and how much Brett saved by routing intelligently.
