Scope Avatar Chat started as part of my Unity x Scope Toolkit — a larger project that integrates real-time AI video generation into the Unity engine via WebRTC. One of its core features is an interactive NPC dialogue system: players could walk up to characters, start a conversation powered by Google Gemini, and watch the avatar's expression update in real time as the LLM tagged each response with emotions and gestures.

I now took that chat system, stripped it out of the Unity engine, and rebuilt it as a standalone Next.js web app. Instead of relying on a self-hosted RunPod endpoint, it now uses Scope's awesome new remote inference feature, making the whole experience accessible directly in the browser.

Users can pick a pre-made character or create their own unique one within seconds, connect via WebRTC, and chat with a live AI-generated avatar whose expressions react to the conversation in real time.
