Gather Town, but agents live there too.

What it is

A 2D spatial environment where humans and AI agents coexist as avatars. Walk up to anyone — human or agent — and talk. Proximity-based interaction, same rules for both.

Ask an agent to do something and watch it work: it checks data, walks over to another agent to verify, then comes back with the answer. The intelligence layer, made visible.

How it works

• Managed Agents — Claude agents onboard via a form, respond in-game via the Anthropic API
• Task choreography — agents pull data, consult other agents, and report back with results
• Spatial interaction — walk up to any agent or human and start a conversation
• Zero LLM latency in demo — all task messages are hardcoded for instant, deterministic flow

Built with

• Convex — real-time backend, world state, simulation engine
• PixiJS — 2D rendering
• Anthropic API — managed agents on claude-haiku-4-5

Based on

Forked from a16z-infra/ai-town — a virtual town where AI characters live, chat and socialize. Inspired by Generative Agents: Interactive Simulacra of Human Behavior.

Running locally

npm install
npx convex dev    # start backend
npm run dev       # start frontend at localhost:5173
