## Every asset your game needs, in one app

Models, textures, music and animation, made by the same AI that writes your code. Image models and music run on your own computer, for free.

| What | Runs | Description |
| --- | --- | --- |
| 3D models in Blender | Free | The app finds or installs Blender, connects it, and the AI builds and edits your meshes in a real Blender. |
| Text to 3D | Cloud · Pro | Describe an object and get a textured, game-ready model generated by AI. |
| Textures & images | Local · Free | Open models like FLUX, SDXL and Qwen-Image run on your GPU. No cloud, no per-image cost. |
| Game music | Local · Free | Compose, render and export soundtracks with SuperCollider, straight into Unity, Unreal or Godot. |
| Rig & animate | Cloud · Pro | Auto-rig characters, add textures and animations, and drop them into your engine. |

## Images, textures and video, made on your own GPU

The app runs open models right on your computer. Nothing is uploaded and nothing is billed: generate as much as you like.

- $0 per image or clip
- 14 open models
- 4 GB of VRAM to start

NVIDIA GPUs from 4 GB and Apple silicon Macs. Each model’s licence applies.

Model families: FLUX.1 schnell, FLUX.2 klein, SDXL, Juggernaut XL, RealVisXL, Animagine XL, Qwen-Image, Qwen-Image-Edit, Z-Image Turbo, LTX-2.5 video, Wan 2.2 video.

## One framework for everything you build

Any engine, any agent, any skill, any plugin, any model. Swap one piece and the rest keeps working.

- Any engine — Unity, Unreal Engine and Godot today, Brutal soon. Same app, same workflow.
- Your agents & skills — Pick an agent for each chat, write your own, and call skills with $.
- Plugins for the AI — Packages add new powers: Blender, music, 3D generation, image and video models.
- Any LLM — GPT-6, Claude, DeepSeek, GLM and more. Choose the model for each chat.

## Free forever. Go Indie when you’re ready.

The App and every engine plugin are free and open source — run everything locally at no cost, no account required. Upgrade to Pro only when you want hosted AI: higher limits, premium models, and zero setup, right from the App.

- Indie — For solo devs going all-in with hosted AI.
- Studio — More throughput for small teams shipping fast.
- Studio Max — Maximum limits for heavy, full-time production.

Cancel anytime · free tier never expires. Plans and prices: https://ai-game.dev/pricing (Markdown: https://ai-game.dev/docs-md/pricing.md).

## Talk to your engine in natural language. It already knows what to do.

261 capabilities across three engines. Every action your AI client can perform is a real MCP tool — and every engine has its own set.

| Engine | Capabilities | Areas | Catalog |
| --- | --- | --- | --- |
| Unity | 72 capabilities | 19 | https://ai-game.dev/docs/tools/unity |
| Unreal Engine | 90 tools | 14 | https://ai-game.dev/docs/tools/unreal |
| Godot | 99 tools | 21 | https://ai-game.dev/docs/tools/godot |

## Already have an AI agent?

Every engine plugin also works on its own with Claude Code, Cursor, Copilot, Gemini and others: an MCP server, a CLI that installs and configures it, and AI skills generated from the tools in your project. The app sets all of this up for you — reach for these only if you bring your own agent.

Supported agents: Claude Code, Open Code, Cursor, GitHub Copilot, Gemini, Codex, Antigravity, VS Code, JetBrains Rider, Visual Studio, Cline, Kilo Code.

| Plugin | Includes | CLI | Install guide |
