Show HN: Open-source AI RP tool with 300 GitHub stars in one month

I'm a 21-year-old student from Wuhan University, and over the past 30 days I’ve built an open-source AI Roleplay engine called Narratium.

It’s designed for people who want to create immersive, long-form AI storytelling experiences — more like a VSCode for interactive narratives than a typical chat app.

I launched it inside the largest AI Roleplay community in China, and got: - 300+ GitHub stars within a month - ~10M daily tokens consumed by real users - Dozens of deep, branching story runs with user-written memory and character setups

## Why I built this

As a long-time RPG fan and hackathon builder, I was frustrated by how most AI tools lose character consistency, forget world context, or aren’t built for narrative control.

So I decided to build my own. Narratium supports: - Markdown-based character sheets - Context memory + world structure tracking - Plugin-style model swapping (OpenAI, Ollama, etc.) - Early support for graph-style memory tables

## What I learned

- Sharing to a niche Discord community gave my first traction (nearly 30% clicked Star) - MVP > perfection - Open source works best when paired with a story people care about

## What's next

Still early, but looking for collaborators, contributors, and feedback from folks interested in: - AI + storytelling tools - open-source interfaces for LLMs - narrative worldbuilding engines

Would love to hear what you think. Thank you!
