OpenRP
What it is
OpenRP is a web-based collaborative engine for creating interactive fiction with worlds, characters, and dynamic narratives. Its visual editor keeps characters, backstory, and locations together, while characters in one world can develop memories of one another. Edited material is vector embedded for retrieval during chats. The visual Behavior Engine combines language-model calls with chats and lore, then supports conditions, loops, parallel branches, and HTTP requests to outside services. Pipelines can send generated messages to a Discord bot. Users can fork worlds, track edits, and propose changes to the original creator. The model picker adjusts context size up to the selected model’s maximum and reports estimated and actual usage costs. A Free plan offers unlimited characters and messages with free AI models; Plus costs $10 a month and adds private worlds, monthly model credits, more detailed personas and slots, feature requests, and priority support.
