World Simulator: Play AI World

Play AI-generated worlds, live. World Simulator is an AI game powered by a real-time world model: every world is a living video, generated on the fly as you play — not pre-made levels, not static images.
Walk, look around, explore. Move through your world with full real-time controls and watch it respond instantly. Every world is unique, and no two sessions are ever the same.
Make things happen. Type what you want to occur — a storm, a stranger, a discovery — and watch the AI game simulation bend the story around your choices. Or let the AI surprise you with unexpected events that change everything.
Create your own worlds. Describe a scene, a character, a story — the world model brings it to life in seconds. Share your worlds and explore thousands created by the community: fantasy realms, historical adventures, sci-fi frontiers and more.
