Altworld

Altworld is a browser-based AI life simulator and story sandbox where your choices actually matter and the world remembers.

Create or choose a living world, complete with factions, NPCs, economy, rumors, laws, and starting pressures, then step inside and live as a person in it. Every action you type in plain English changes the situation. Characters remember what you said. Past decisions create lasting consequences. Scarcity, social obligations, politics, and personal stakes drive emergent, replayable stories.

Play historical runs, sci-fi survival, alternate history, or completely original worlds. One sentence can shift everything around you.

Features:

• Persistent simulation with real memory and consequences

• Freeform text input, describe any action, the world responds intelligently

• Curated and community worlds with weekly events and Run of the Week

• Deep systems: pressure, suspicion, rumors, supplies, obligations, and more

• Turn-based with guided first runs for new players

Perfect for fans of thoughtful life sims, emergent narrative games, and AI-driven storytelling that feels alive.
