Inworld has been pioneering character-first, real-time AI interaction since our inception. We began by pushing the frontier of lifelike, interactive characters for games and entertainment—characters that could form relationships, express emotions, remember conversations, and respond naturally through voice. With Runtime, we’re taking that character-building expertise to the next level. Runtime is Inworld’s new AI orchestration platform that gives developers unprecedented control and flexibility to build sophisticated AI characters and voice agents.

From Studio to Runtime

If you’ve previously used Inworld Studio to create AI characters, Runtime offers all those same powerful capabilities—knowledge retrieval, safety checks, long-term memory, and expressive voice synthesis — but with a more customizable and flexible approach. By taking the same tools that powered AI characters in Studio, and providing them as a composable toolkit through Runtime, we are empowering developers with full visibility and control over their AI characters.
