This in-depth post compares the ChatGPT Work desktop app and the Claude Cowork desktop app, focusing on how each "desktop agent" executes tasks, connects to applications, and structures its product.

1. Execution Architecture

Claude Cowork: Runs an isolated Linux VM sandbox locally. File operations occur within this sandbox, allowing generated .docx / .xlsx / .pptx / .pdf files to be saved directly to designated folders.
ChatGPT Work: Inherits Codex's sandbox and permission system, utilizing native OS isolation (macOS Seatbelt, Windows Sandbox). It features a built-in browser, enabling web access and tool operation without needing extensions.

2. Computer Interaction

ChatGPT Work: Its Computer Use feature can operate other apps in the background, displaying a secondary cursor to show it's moving independently of the user.
Claude Cowork: Also supports Computer Use but remains in research preview. It can control browsers via a Chrome extension or interact with desktop apps directly.

3. App Connectivity

ChatGPT Work: Employs a unified plugins directory with 60+ connectors for Slack, Teams, Google Drive, SharePoint, and Salesforce. Apps can be called directly in prompts using @.
Claude Cowork: Uses MCP (Model Context Protocol) connectors for Slack, Notion, HubSpot, Jira, and Linear. It also offers 11 official industry plugins and supports custom-built ones.

4. Product Structure

ChatGPT: The desktop app integrates Chat, Work, and Codex modes into a single application for seamless switching.
Claude: Its desktop app is also undergoing a redesign, evolving from its original three-tab layout (Chat, Cowork, Code) into a new structure.
