Unity AI (formerly Muse)

Unity AI is the successor to Unity Muse, which the company has now deprecated, and it lives directly inside the Unity 6 editor rather than in a browser. It ships as three components. Assistant is a generative chat panel that answers technical questions, automates routine editor tasks, writes C# and can operate agentically across a project. Generators produce sprites, tileable textures and animations from text prompts or reference images, drawing on third party models including Scenario and Layer LoRAs for sprites, Unity's own model for textures, and Unity plus Kinetix models for animation. Inference Engine, previously called Sentis, runs custom neural networks locally inside the editor or in a shipped runtime. Two things make the 2026 version notable beyond the generation itself: an AI Gateway that lets you route work to your own Anthropic or OpenAI subscription without those calls consuming Unity credits, and an official MCP Server that exposes project data to external assistants and IDEs. Every generated asset carries embedded metadata flagging it as AI generated, which matters for app store declarations and rights tracking.
