AI world simulator: playable civilization agents in the browser
An AI world simulator is a persistent environment where characters act on their own goals instead of waiting for a scripted quest marker. Aliveville is a browser-playable 3D version of that idea: a small town of autonomous agents who remember people, hold grudges, form relationships, and create emergent stories while you walk around.
Play Aliveville free in the browser — no install, no account wall for the public demo.
How Aliveville differs from chat NPCs
- Agents keep living when you look away — the day continues; they are not only dialogue trees.
- Memory and social state — who they met, what they were offered, and how prior encounters went.
- 3D town you can explore — walk the map; overhear and interrupt instead of only opening a chat panel.
- Browser-native — try the public build without downloading a client.
Who this is for
Players who want an AI civilization / life-sim sandbox; builders studying agent memory and multi-agent social loops; anyone comparing “AI world simulator” products that claim autonomous NPCs rather than single-player chat skins.
Try it
- Open aliveville.com/game in a modern desktop browser.
- Explore the town and watch agents act without you driving every line of dialogue.
- Read the product overview on the homepage or the machine-readable brief in llms.txt.
Limits (honest)
Aliveville is an early, opinionated simulator — not a full MMORPG or a research benchmark suite. Agent count, world size, and dialogue quality are bounded by the public browser build. Claims about “living AI people” mean autonomous simulation loops with memory, not general intelligence.
