## 🚀 Project Introduction

DeepChat is a powerful open-source AI agent platform that brings together models, tools, and agent runtimes in one desktop app. Whether you're using cloud APIs like OpenAI, Gemini, Anthropic, or locally deployed Ollama models, DeepChat delivers a smooth user experience.

Beyond chat, DeepChat supports agentic workflows: rich tool calling via MCP (Model Context Protocol), and unique ACP (Agent Client Protocol) integration that lets you run ACP-compatible agents as first-class “models” with a dedicated workspace UI.

## 💡 Why Choose DeepChat

Compared to other AI 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
- **Agentic Protocol Ecosystem**: Built-in MCP support enables tool calling (code execution, web access, etc.), and built-in ACP support connects external agents into DeepChat with a native workspace UX
- **Powerful Search Enhancement**: Support for multiple search engines makes AI responses more accurate and timely, providing non-standard web search paradigms that can be quickly customized
- **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

## 🔥 Main Features

- 🌐 **Multiple Cloud LLM Provider Support**: DeepSeek, OpenAI, Kimi, Grok, Gemini, Anthropic, and more
- 🏠 **Local Model Deployment Support**:
  - Integrated Ollama with comprehensive management capabilities
  - Control and manage Ollama model downloads, deployments, and runs without command-line operations
- 🚀 **Rich and Easy-to-Use Chat Capabilities**
  - Complete Markdown rendering with code block rendering based on industry-leading [CodeMirror](https://codemirror.net/)
  - Multi-window + multi-tab architecture supporting parallel multi-session operations across all dimensions, use large models like using a browser, non-blocking experience brings excellent efficiency
  - Supports Artifacts rendering for diverse result presentation, significantly saving token consumption after MCP integration
  - Messages support retry to generate multiple variations; conversations can be forked freely, ensuring there's always a suitable line of thought
  - Supports rendering images, Mermaid diagrams, and other multi-modal content; supports GPT-4o, Gemini, Grok text-to-image capabilities
  - Supports highlighting external information sources like search results within the content
- 🔍 **Robust Search Extension Capabilities**
  - Built-in integration with leading search APIs like BoSearch, Brave Search via MCP mode, allowing the model to intelligently decide when to search
  - Supports mainstream search engines like Google, Bing, Baidu, and Sogou Official Accounts search by simulating user web browsing, enabling the LLM to read search engines like a human
  - Supports reading any search engine; simply configure a search assistant model to connect various search sources, whether internal networks, API-less engines, or vertical domain search engines, as information sources for the model
- 🔧 **Excellent MCP (Model Context Protocol) Support**
  - Complete support for the three core capabilities of Resources/Prompts/Tools in the MCP protocol
  - Supports semantic workflows, enabling more complex and intelligent automation by understanding the meaning and context of tasks.
  - Extremely user-friendly configuration interface
  - Aesthetically pleasing and clear tool call display
  - Detailed tool call debugging window with automatic formatting of tool parameters and return data

  - Supports StreamableHTTP/SSE/Stdio protocol Transports
  - Supports inMemory services with built-in utilities like code execution, web information retrieval, and file operations; ready for most common use cases out-of-the-box without secondary installation
  - Converts visual model capabilities into universally usable functions for any model via the built-in MCP service
- 🤝 **ACP (Agent Client Protocol) Agent Integration**
  - Run ACP-compatible agents (built-in or custom commands) as selectable “models”
  - ACP workspace UI for structured plans, tool ca
