Narratomi vs OpenRP

Narratomi is a browser-based studio for writing and staging branching narrative games. Its editor places a live 3D stage alongside the script and choices, while a flow graph maps story routes and checks them as you write. Slash commands add choices, variables, and stage directions without code, and the compiler flags broken paths. Co-writers can work in the same scene live, and writers can create checkpoints, branch drafts, restore versions, and merge changes. Its AI staff writer drafts on its own branch, so writers can review, merge, rewind, or discard that work. Published stories open from a browser link without requiring a player account; anyone with the link can access them until they are unpublished. Writing, staging, and playing work in a modern desktop or phone browser without installation. User-created stories, scripts, and assets remain theirs. The free plan includes two projects, 50 monthly AI credits for mini models, 0.5 GB storage, and 1,000 monthly plays. Creator costs $12 per month billed annually and includes unlimited projects, 7,500 monthly AI credits, 5 GB storage, and 20,000 monthly plays.

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.
