This Node.js package provides an unofficial client for Microsoft's Bing Chat, offering a powerful AI conversational experience similar to ChatGPT but with enhanced capabilities. It is designed for developers and researchers interested in integrating Bing Chat's AI into their applications or exploring its functionalities.

How It Works

The client acts as a reverse-engineered wrapper around the Bing Chat API. It leverages Node.js and requires a valid Bing Chat cookie (_U cookie) for authentication. The library supports asynchronous message sending, conversation history management, and real-time streaming of responses via an onProgress handler, allowing for dynamic UI updates. Users can also select different AI variants like "Balanced," "Precise," or "Creative."
