Hi HN,
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!
