Welcome to Kepler

Kepler is an AI coding agent that plans, edits, runs, and tests your code. You can use it from your terminal, from a cloud workspace, or wire it into Studio workflows.

These docs cover the CLI — the fastest way to get productive with Kepler today. If you’re new, start with Getting Started. If you already have Kepler installed and want to know what the slash commands do, jump to Commands.
