What OpenRP is
OpenRP is a web-based collaborative engine for creating interactive fiction. Its visual editor brings characters, backstory, and locations together, while characters in one world can develop memories of one another. Edited content is vector embedded so it can be retrieved in chat. Creators can fork worlds, track edits, and suggest changes to the original creator.
The visual Behavior Engine connects language model calls with chats and lore, then supports conditions, loops, parallel branches, and HTTP requests to outside services. Pipelines can also send generated messages to a Discord bot. A model picker adjusts context size up to the selected model’s maximum, and the platform reports estimated and actual usage costs. OpenRP offers a free plan with unlimited characters and messages using 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 people aged 18 and older.
