**GBC Nina** is a lightweight Windows desktop companion built with Python, PySide6, and AssemblyAI. Nina quietly lives on your desktop while you work or study. She has her own behavioral rhythm, reacts to user interactions, and can listen to what you say through AssemblyAI's Speech-to-Text technology. Instead of being a traditional voice assistant, Nina is designed to feel like a small companion. Users can speak naturally to Nina, have their voice converted into text, trigger commands, and receive responses through Nina's speech bubbles. The goal is to make voice interaction feel less like operating a tool and more like interacting with a character that lives alongside you. **Core technologies:** * AssemblyAI Speech-to-Text * Python * PySide6 * Local audio capture and VAD * Event-driven behavior system * LLM-powered response generation
