The brief

Meblur set out to build a creator-driven social network where users create AI characters and run live, multiplayer roleplay sessions powered by LLMs, not a single app, but three synchronized systems that all had to work together in real time.

The problem

Most "AI app" builds bolt a chatbot onto an existing product. Meblur needed the AI woven into the core mechanic, multiplayer sessions where an LLM drives in-character dialogue live, with moderation and admin oversight running in parallel, all keeping state in sync across mobile, backend, and dashboard simultaneously.

The approach

We built the React Native mobile app where users create characters and run LLM-powered roleplay sessions, a Node.js backend with MongoDB and Redis caching integrating Hugging Face and OpenAI for in-character dialogue generation, and a Next.js admin dashboard for live moderation, reporting, and bans, all synchronized through Firestore subscriptions and Socket.io so state never drifts between the three.

Result

A production AI social platform spanning mobile, backend, and admin tooling, architected and delivered as one system by one team, not split across three vendors with integration gaps between them.
