In their own words
OpenRP
OpenRP is a web-based collaborative engine for building interactive fiction with worlds, characters, and dynamic narratives. Its visual world editor combines characters, backstory, and locations. Characters in one world can develop memories of each other, while edited content is embedded for retrieval in chat. The Behavior Engine connects language-model calls with chats and lore using conditions, loops, parallel branches, and HTTP requests. Pipelines can send generated messages to a Discord bot. Users can fork worlds, track edits, and propose changes to the original creator. Model controls expose context limits and estimated and actual usage costs. The Free plan has unlimited characters and messages with free AI models; Plus costs $10 a month and adds unlimited public and private worlds, monthly model credits, expanded personas and slots, feature requests, and priority support.
