OpenRP
What OpenRP is
OpenRP is a web-based, node-based environment for building interactive fiction with worlds, characters, and changing narratives. Its visual editor brings a world’s characters, backstory, and locations together for editing. Characters sharing a world can form memories of one another, and edited content can be retrieved in chats. The visual Behavior Engine connects language model calls with chats and lore, using conditions, loops, parallel branches, and HTTP requests to shape behavior. Pipelines can also send generated messages to a Discord bot. Creators can fork worlds, follow edits, and suggest changes to the original creator. A model picker supports context-window adjustments up to the selected model’s maximum; OpenRP reports estimated and actual usage costs. The Free plan offers unlimited characters and messages with free AI models. Plus costs $10 a month and includes $10 Model Credits monthly, unlimited public and private worlds, more detailed personas and more slots, feature requests, and priority support. The service is intended for users aged 18 and older.
