Open Cowork: An Open-Source AI Desktop Assistant

Open Cowork is an open-source implementation of Claude Cowork, providing one-click installation packages for Windows and macOS, usable without programming.

It offers a sandboxed workspace where AI can manage files through a built-in Skills system, generate professional outputs (PPTX, DOCX, XLSX, etc.), and connect to desktop applications (browsers, Notion, etc.) via MCP for better collaboration.

Core Features

• One-Click Installation, Ready to Use: Provides pre-built installation packages for Windows and macOS, requiring no environment configuration; simply download and use.
• Flexible Model Support: Supports Claude, OpenAI-compatible APIs, and Chinese models like GLM, MiniMax, and Kimi. It can use API keys from platforms like OpenRouter and Anthropic, offering flexible configuration. More models are coming soon.
• Remote Control: Can connect to collaboration platforms like Lark and other remote services to automate workflows and enable cross-platform operations.
• GUI Operation: Supports controlling and interacting with various desktop GUI applications on your computer. It is recommended to use the Gemini-3-Pro model for optimal GUI understanding and control.
• Intelligent File Management: Read, write, and organize files within the workspace.
• Skills System: Built-in workflows for generating and processing PPTX, DOCX, PDF, and XLSX files, with support for creating and deleting custom skills.
• MCP External Service Support: Integrates browsers, Notion, custom applications, etc., through the MCP connector to extend AI capabilities.
• Multimodal Input: Directly drag and drop files and images into the chat input box for seamless multimodal interaction.
• Real-Time Tracking: View the AI reasoning and tool execution process in the Trace panel.
• Secure Workspace: All operations are restricted to the user-selected workspace folder.
• Virtual Machine-Level Isolation: Implements virtual machine isolation through WSL2 (Windows) and Lima (macOS). All commands are executed in an isolated virtual machine, protecting the host system.
• UI Enhancement: Beautiful and flexible UI design, supports system language switching, and fully displays MCP/Skills/Tools calls.
