LingChat is an AI companion chatbot designed to provide an engaging and emotionally expressive conversational experience. It targets users seeking interactive AI partners, offering features like persistent memory, emotional expression, and customizable characters.

How It Works

LingChat integrates a proprietary AI emotion recognition model to dynamically adjust the AI's expressions, animations, and dialogue tone. It employs a custom RAG system for enhanced memory and supports VITS for realistic voice synthesis, aiming for a more immersive and personalized interaction.

Limitations & Caveats

• Voice generation can be slow (up to a minute per utterance) on integrated graphics or older hardware, with potential for errors; GPU is highly recommended for voice features.
• Windows Defender may flag the executable as a virus.
• Users on older hardware might need to access the application via localhost:8765 in a browser if the executable fails to load.
