Unity AI Assistant – Natural Language Automation for Unity Development

Overview

Unity AI Assistant is a Unity Editor extension developed as part of a Bachelor's thesis in cooperation with Capgemini Germany.
It integrates large language models (LLMs) into the Unity Editor to allow the creation of Unity objects, components, and scripts based on natural language prompts.
The tool streamlines repetitive development tasks and supports Unity developers with intelligent code and object generation.

🧠 Powered by OpenAI's GPT API
🧰 Built for Unity 2022.3 (LTS)
