Unreal Engine BlueprintAIAssistant - AI-powered Blueprint creation and manipulation

BlueprintAIAssistant is an Unreal Engine assistant agent designed to help you manage and interact with your entire project. It supports Claude, OpenAI, OpenRouter by default, plus a custom endpoint option—giving you full flexibility in how you use AI inside Unreal Engine.
Its goal is to act as a powerful agent capable of creating, modifying, deleting, and debugging Blueprints, working with actors, and performing project‑wide operations that go far beyond traditional tools.
Please note that BlueprintAIAssistant is currently in ALPHA, meaning some features may be incomplete, missing, or not functioning as intended.
If you encounter issues, you can export the chat log, and an optional additional log is generated on your desktop. Sharing these with me—such as through the support channels or Discord—will help improve the plugin.

Check whether your project folder contains a Plugins folder.
If it doesn’t, create it manually.

Unpack the contents of the ZIP file into the Plugins folder.

Open your project by double‑clicking the .uproject file.

The first time you open it, a pop‑up will appear saying the plugin needs to be built.
Click Yes to continue.

If the build fails, it often means the project is new. Try opening it again a couple of times.

After it succeeds, everything should work correctly—enjoy!

The current plan is to develop this into a fully autonomous system that is fully aware of your project.
What does this mean?

It will be capable of handling anything you ask.
It will be able to create complex tasks, including fully playable game logic.
It will support both Blueprint and C++ implementation.

For example:

Right now, Blueprint has no node to retrieve the user’s desktop location.
In the future, you could simply instruct the AI to create a C++ node that exposes a Blueprint function to print the user’s desktop location.

So, I hope you understand the direction this is heading.

The final price : between 200-500 €

Try to use the latest models such as GPT‑5.3 or Claude 4.6. Older models may not be trained with much XML or similar command formats
