About Inworld AI

Inworld AI is an advanced character engine designed to power autonomous, intelligent non-player characters (NPCs) in video games, virtual worlds, and XR simulations.

The platform combines multiple machine learning models to orchestrate real-time natural language dialogue, emotional intelligence, voice synthesis, facial animations, and context-aware behavior trees.

Developers can configure character personalities, memories, knowledge boundaries, and relationship dynamics in the Inworld Studio, deploying them seamlessly into game engines like Unreal Engine, Unity, and Roblox via dedicated SDKs.
