RPG OS is a free, open-source system for playing persistent games through a capable AI. Describe almost any world, become someone inside it, and decide what you do through normal conversation. Instead of depending entirely on an ever-growing chat history, RPG OS maintains the campaign in readable files: current state, characters, relationships, possessions, unresolved consequences, history, and supporting evidence.
