🚀 Project Introduction

DeepChat is a powerful open-source AI chat platform providing a unified interface for interacting with various large language models. Whether you're using cloud APIs like OpenAI, Gemini, Anthropic, or locally deployed Ollama models, DeepChat delivers a smooth user experience.

As a cross-platform AI assistant application, DeepChat not only supports basic chat functionality but also offers advanced features such as search enhancement, tool calling, and multimodal interaction, making AI capabilities more accessible and efficient.

💡 Why Choose DeepChat

Compared to other AI chat tools, DeepChat offers the following unique advantages:

• Unified Multi-Model Management: One application supports almost all mainstream LLMs, eliminating the need to switch between multiple apps
• Seamless Local Model Integration: Built-in Ollama support allows you to manage and use local models without command-line operations
• Powerful Search Enhancement: Support for multiple search engines makes AI responses more accurate and timely
• Advanced Tool Calling: Built-in MCP support enables code execution, web access, and other tools without additional configuration
• Privacy-Focused: Local data storage and network proxy support reduce the risk of information leakage
• Business-Friendly: Embraces open source under the Apache License 2.0, suitable for both commercial and personal use
