Getting Started

Brody AI is an AI agent that lives inside the Unity Editor. It writes C#, builds scenes, plans enemy AI, and verifies its own work — all from a chat window, with no Python and no local setup beyond a lightweight gateway.

What Brody AI is

  • 76 tools covering scene building, level design, code analysis, asset generation, package management, memory, and more.
  • 10-agent orchestration — for complex requests, specialized sub-agents (Coder, SceneBuilder, Verifier, ErrorHandler, and more) spawn and execute a parallel plan with a verify/fix loop.
  • C# native — built on Unity UI Toolkit. No Python, no pip, no local model downloads.
  • Unity 2021.3+ on Windows, macOS, and Linux editors.
  • Approval service — destructive operations are gated behind explicit approval, with an auto-approve mode for fully-automated runs.
  • Cross-session memory — the agent recalls your project state between sessions so it never feels amnesiac.

Install in three steps

1. Install the package

Import the Brody AI unitypackage into your project, or install via Unity Package Manager with the git URL.
