WorldOS – A fully customizable AI simulation sandbox game

Forget video games with fixed storylines. A new platform called WorldOS is pitching itself as something far more ambitious: an entire operating system for AI-driven simulated worlds.

Users can drop into community-built universes spanning war history, romance, sci-fi, and anime, or build their own from scratch, no coding required. Inside each world, an AI game master keeps everything coherent, driving characters, social feeds, in-world stock markets, and even a simulated web browser, all reacting in real time to whatever the user types.

Creators can install apps, define rules, and publish worlds for others to remix and reshape.

Currently free in beta, the platform plans to move to a credit-based model, though members can plug in their own AI API keys. It's a bold vision: less chatbot, more living, breathing fictional universe, with you holding the controls.
