Forge a world

AI Worldbuilding Game

Describe a setting in plain language. Altworld turns it into a structured scenario you can revise, publish, share, and play.

For worldbuilders who want their setting to become a playable simulation rather than a static document.

Worlds become data

Generated settings include locations, factions, NPC templates, laws, rumors, starting threads, and economy pressure.

Saved worlds can become public worlds that other players start from or duplicate into their own library.

The forge is not just a lore generator. It feeds the run setup and turn simulation.
