FR-AI / ANALYSISWhy it is worth attention
It offers a full pipeline approach with multiple specialized LLM calls per turn, a character phone with social media, banking, and notes apps, optional image and voice generation via ComfyUI, and strong privacy with local-only storage and encryption.
Who it is for
- AI roleplay enthusiasts
- Writers seeking structured AI-assisted storytelling
- Privacy-conscious users who prefer local AI tools
- Developers interested in visual node workflows for LLM pipelines
Use cases
- Creating and playing through interactive narrative roleplay scenarios with multiple characters
- Running a fully local AI roleplay experience without internet or subscription
- Building complex story pipelines with dynamic prompt selection and scheduling events
- Developing character-driven stories with integrated social media and messaging simulation
Strengths
- Local and private: no cloud account or subscription required, all data stored as files on disk with optional encryption
- Modular pipeline: each turn uses multiple focused LLM calls with per-node model selection, allowing mixing small and large models
- Rich in-world phone: characters can text, post, bank, and take notes, with messages appearing inline in the roleplay
- SillyTavern character import support and built-in assistant for debugging workflows
Considerations
- Beta software (v0.4.9) from a hobby project with expected bugs and limited support
- Strongly recommended to use a specific model (Gemma 4 31B) for reliable JSON output; RP finetunes may struggle
- Requires Git and Node.js 24 for setup; not a turnkey install for non-technical users
README quick start
🎭 RPgraph Studio
Your personal roleplay engine — powered by your own AI, running entirely on your machine.
🎬 Demo video: https://youtu.be/nweut7o-qnA
RPGraph Studio is a local-first desktop app for interactive AI roleplay. Instead of a plain chatbox, you get a full studio: a visual node workflow decides how your story is built, a rich RP chat shows the results, and an in-world character phone with its own apps brings the story world to life.
No cloud account. No subscription. Your stories stay on your computer. 🔒
✨ Why RPgraph Studio?
- 🧩 A pipeline, not a mono-prompt. Each turn is split into several focused LLM calls: translation, the actual response, then after-work like speaker marking, story-time tracking, and event preparation.
- 🔀 The right prompt for every moment. Normal reply, phone text, narrator turn, social post, event — each situation gets its own prompt through the graph, automatically.
- 📱 A phone full of apps. Characters text, post, and bank on an in-world phone whose messages appear inline in the story.
- 📖 Story memory. Storybooks hold characters, world context, and images — including SillyTavern character imports — with a built-in assistant to create and edit them.
- 🎛️ Mix and match models. Every LLM node can use its own connection: a small local model for simple jobs, a bigger model for the actual roleplay.
- 🏠 Local & private. Connects to LM Studio, Ollama, llama.cpp (router mode), OpenRouter, or Google Gemini. Optional ComfyUI connections add image and voice generation. Everything is saved as files on your disk — optionally encrypted.
🚀 Features
🕸️ Visual Node Workflow
- Build your RP pipeline from nodes: user input, LLM prompts, story context, history, routing, output.
- LLM Prompt Switch nodes pick the matching prompt variant automatically — normal RP, phone, social media, AutoTurn, narrator, events, Autoplay.
- Live node colors show what's running, finished, prepared, or failed.
💬 Roleplay Chat
- Combined timeline where phone and app messages appear inline inside the roleplay.
- Character selection, narrator mode, drafts, image attachments, editing & regeneration.
- 🎨 Spoken text highlighting: quoted dialogue is colored per character.
- ⏰ In-world time tracking: the LLM estimates passed time and time
