WorldX

WorldX is a multi-agent simulation platform that generates interactive virtual worlds and characters from simple text prompts.

WorldX generates complete virtual environments including maps and characters based on user-provided descriptions. The system utilizes multiple AI agents to drive character decision-making, relationship building, memory retention, and dialogue generation. Users can influence the simulation via God mode to edit character attributes, inject events, or engage in direct conversations with inhabitants. It supports multi-day temporal evolution and maintains a timeline system for complex world-building. The platform requires Node.js and configuration of specific LLMs for orchestration, image generation, vision, and simulation duties.
