Installation

Run the setup script that find and install the correct version.

On Max or Linux:

curl -fsSL https://kaja.io/setup.sh | bash

On Windows:

irm https://kaja.io/setup.ps1 | iex

Or grab directly from GitHub Releases — x64 and arm64.

First run

Run kaja. If no config exists yet, a one-time setup wizard asks how you want to chat:

Free hosted chat — nothing else to configure, works immediately.
Bring your own provider — writes a starter models.toml for either Fireworks AI or a local Ollama install, which you then fill in with your own credentials/models (see Configuration).

Running in a non-interactive shell (scripts, CI) skips the wizard and writes the default template untouched.
