MetroPrompt

MetroPrompt is an agentic pixel art city builder where AI agents collaboratively design and construct a city from your prompts alone. A planner agent and zone sub-agents work together to lay roads, place buildings, and grow neighborhoods in real time. Citizens with Claude-powered brains are spawned into the city, each with unique personalities, needs, and jobs that drive their daily behavior across a 7-day simulation. As AI agents grow more capable, MetroPrompt points toward a future where city planners can rapidly prototype urban layouts, stress-test infrastructure decisions, and observe emergent citizen behavior before a single brick is laid in the real world.
