FAQ

Quick answers to the questions people ask most about the AI Game Dev desktop app and the gamedev CLI. Each answer links to the page with the details.

General#

What is the AI Game Dev app?#

It is the AI game development app of AI Game Developer: an AI agent that edits your project's files and drives your Unity, Unreal or Godot editor through the engine's MCP plugin. It comes as a desktop app and as the gamedev CLI. See the overview.

Should I use the desktop app or the CLI?#

Use the desktop app for everyday work: panes, previews, Source Control and the Packages window. Use the CLI in a terminal, over SSH, in scripts (gamedev --print) or inside ACP clients such as T3 Code or Zed (gamedev acp). Both share one account, background service and chat history on a computer.

Which engines are supported?#

Unity 2022.3 LTS or newer, Unreal Engine 5.5 or newer (C++ projects) and Godot 4.3 to 4.5 (.NET). You can also chat in any other folder without engine tools. See Projects and engines.

Which operating systems are supported?#

The desktop app: Windows x64, macOS (Apple silicon and Intel) and Linux x86_64. The CLI: Windows x64, macOS arm64 and x64, Linux x64 and arm64. See Installation.

Do I need to install the engine plugin myself?#

No. Open your project and click Install Package in the sidebar, or run /install-plugin in the CLI. A project created from the app gets the plugin automatically. The installers ship inside the app, so you need no Node.js or npm for the desktop app.

Account, plans and usage#

Do I need an account?#

Yes. Sign in with your AI Game Developer account in the app or with /login in the CLI. See Sign-in and account.

Which plan do I need?#

It depends on the models and tools you want. Plans are Free, Indie, Studio and Studio Max, and there is a free trial. Some models and paid tools need Studio or higher. Compare them on the pricing page.

How is usage shown?#

As a percentage of your monthly allowance, where 100% is the full allowance of your plan. Chat turns and paid operations such as Tripo or cloud video use part of it; local models on your computer do not.

Why can I not choose a model?#

Its plan, your billing-address region or an age requirement rules it out; the reason is shown under the model's name. The current list is on the model availability page.

Packages#

What is a package?#

An extension of the app itself: a folder with an aigd-package.json manifest and optional code that adds tools, commands, panels, editors or models. See Packages.

Which packages come with the app?#

Blender, SuperCollider (Music), Knowledge Base, Tripo and the local image and video runtime are installed by default. The local models and cloud model families are separate packages. See the packages catalog.

Does every chat carry every package?#

No. Each session switches tools on in its Tools row, so the agent's context stays small. A change applies from the next message.

Can I write my own package?#

Yes. Develop it in a local folder with gamedev pkg link or gamedev pkg dev, then share it through GitHub or npm. See Creating packages.

How do packages differ from Claude plugins and MCP servers?#

Packages extend the app; Claude plugins add skills, commands and agents to the Claude agent; MCP servers add tools from any MCP server to one project. Plugins and MCP servers are managed in Settings or with /plugin and /mcp.

Models and generation#

Can I generate images or video on my own GPU?#

Yes, with the local image and video models run by stable-diffusion.cpp. Most need an NVIDIA GPU; Z-Image Turbo also runs on other GPUs, and FLUX.2 klein 4B on Apple silicon. Local generation is free. See the hardware table.

Can I generate video and audio without a GPU?#

Yes, with Cloud generation on paid plans: video models such as Veo, Kling and Seedance, and audio with ElevenLabs, Kokoro, Lyria and ACE-Step. Every job asks first or stays within a budget you set as a percentage of your allowance. See Cloud generation.

Can the agent model in Blender?#

Yes. Type /blender to find or install Blender 4.2 or newer and connect it, then switch Blender on in the session. See Blender.

Privacy and control#

Does the agent change files without asking?#

In the default mode, the agent works inside your project without asking and asks when it reaches outside it. You can make it ask every time, or never. See approvals and permissions.

Is my project code stored on your servers?#

Your project stays on your computer. The engine connection relays MCP messages between the agent and your editor and does not store tool-call payloads; see the site FAQ for the data the MCP server keeps. The prompts and files the agent reads are sent to the AI model you chose so it can answer. Usage data and error reports are controlled in Settings, Privacy.

Can I use my own AI client instead of the app?#

Yes. The engine plugins work with any MCP client, such as Claude Code, Cursor, VS Code or Codex. Point it at the MCP endpoint and let it authorize; see Authentication and each engine's connecting guide for Unity, Unreal and Godot.

Updates#

How do I update?#

The desktop app updates itself and shows Restart to update. The CLI updates with gamedev update. Packages update automatically unless you switch that off per package. See Installation.

Where can I see what changed?#

On the release notes page.
