AI Town

AI Town is an open-source framework for building interactive, AI-driven multiplayer worlds in the browser. Developed by Convex, it provides a full-stack template that combines large language models with real-time web infrastructure, allowing developers to create towns populated by autonomous AI agents that converse, move, and react to user input. The framework handles core systems such as agent memory, message passing, world state management, and persistent storage, so developers can focus on designing behaviors, narratives, and interactions rather than low-level plumbing.

Key capabilities include customizable agent personalities, configurable world rules, and support for multi-user sessions where humans and AI agents coexist in the same environment. AI Town integrates tightly with Convex’s backend-as-a-service to provide real-time updates, serverless functions, and database operations without manual API or database setup. Use cases include prototyping social simulations, experimenting with emergent behavior, building AI-powered role-playing environments, and teaching or demonstrating multi-agent systems.
