Inworld AI

Inworld AI is a platform for building AI characters for games and interactive experiences. Developers describe a character's personality, background knowledge, goals and relationships, and the Inworld runtime generates dialogue and reactions when players talk to them.

It offers SDKs and plugins for engines including Unity and Unreal, so characters can be connected to in-game actions, emotions and voices. Studios use it for companions, quest givers and other characters where scripted dialogue trees would be too limited. Live AI dialogue adds a cost and a delay to each conversation and can drift off script, so test characters with players who try to break them, limit what each character knows, and keep fallback lines for topics it should avoid. Check how conversation data is stored, especially for games that younger players can reach.
