WorldArchitect.AI is a persistent browser fantasy RPG on the 5e SRD rules. Dice rolls are evaluated server-side so the rules are not left to the LLM. Worlds persist across sessions, characters level up using the 5e SRD progression, and "god-mode directives" let a narrator (or an agent) steer the campaign while keeping state consistent.
The player manual lives at the project wiki.
It is built and operated by Jeffrey Lee-Chan.
