Civ Builder

Choose the AI that governs your people, write the laws, and watch ten autonomous citizens live, vote, trade, and clash. Every run is different — nothing is scripted.

You don't move the pieces in Civ Builder — you set the rules and let an artificial intelligence run a society inside them.

Choose one of five governing archetypes — the intelligence that shapes how your citizens reason about each other, their work, and their laws. Write the legal code: decide what's forbidden and how strictly it's enforced. Then begin, and watch ten autonomous agents live their lives in a real-time event feed.

They work and eat. They vote. They trade and innovate. They commit crimes — and face the punishments you wrote. Out of thousands of small decisions, a civilization takes shape: it can flourish into a stable, inventive society, or fracture and collapse under its own laws. Nothing is scripted. Every run unfolds differently.

GOVERN, DON'T MICROMANAGE

• Pick the AI archetype that governs your people's reasoning.
• Author a living legal code and rewrite it mid-run to steer the outcome.
• Intervene on the fly — inject events and change the law as a crisis unfolds.

A SOCIETY THAT RUNS ITSELF

• Ten autonomous agents make their own choices about work, food, voting, trade, and crime.
• Emergent outcomes: no fixed win condition, no two runs alike.
• A live event feed narrates everything as it happens.

BUILT TO RESPECT YOU

• 100% offline — the entire simulation runs on your device.
• No accounts, no ads, no analytics, no tracking. We collect zero data.
• Saved runs live on your device and never leave it.

Set the laws. Choose the mind that enforces them. Then find out what kind of civilization you've created.
