An AI assistant that works inside Unreal Engine, not next to it

ChatGPT and Claude can explain Unreal Engine, but they cannot see your project. Ultimate Engine CoPilot lives in the editor with 1,655 native tools, so the work lands in your project, compiled and tested.

What people use it for

  • Writing Blueprint functions and event graphs from a description (AI Blueprint generator).
  • Turning a game design document into a task-by-task build plan, then building it with Crew agents.
  • Converting Blueprints to C++ (Blueprint to C++).
  • Testing multiplayer replication with a server and up to 8 clients.
  • Finding frame-rate killers with Unreal Insights.
  • Building PCG forests, landscapes and levels, UI, animation and Sequencer cinematics.
  • Automating tedious editor work: settings, other plugins' panels and repeated setups.
  • Generating 3D models, textures, sound and music without leaving the editor.

Use the AI you want

BpLabs Premium with a plan, your own API keys, local models through Ollama or LM Studio, or the coding agents you already use (Claude Code, Codex, GitHub Copilot, Gemini CLI) through MCP. The license works with all of them.

Frequently asked questions

Is this the same as GitHub Copilot?

No. GitHub Copilot completes code in your IDE. Ultimate Engine CoPilot works inside the Unreal Editor and builds Blueprints, materials, Niagara, PCG, UI and more, as well as C++. You can use GitHub Copilot as one of the AI options.

Which Unreal Engine versions does it support?

Unreal Engine 5.5 to 5.8 on Windows and macOS. It needs an engine installed through the Epic Games Launcher.

Can a team use it?

Yes. Teams buy seats with volume pricing and one invoice, and local models keep project data on the studio's own machines.

Who makes it?

BlueprintsLab, two developers who release roughly every two weeks and answer directly on Discord.
