LinguaCam live: AI-Translated Global Captions, Unified Dynamic Chat, and Interactive Stream Widgets.

LinguaCam live is a professional OBS overlay suite that provides AI-translated global captions, unified dynamic chat, and interactive stream widgets. The project evolved from a simple overlay into a real-time interaction dashboard, tackling latency and clutter challenges through a custom React hook (useYouTubeChat) for instant message capture, in-flight translation middleware, and Socket.io WebSockets for synchronized bullet chat delivery across all connected clients.
