Cowork — Claude Code for Desktop
Cowork brings Claude Code's agentic capabilities to the Claude desktop app, making agentic workflows accessible without a terminal.
How it works:
- Open the Claude desktop app (download at claude.com/download)
- Give Claude access to a folder on your computer
- Set a task and let Claude work autonomously
- Claude loops you in along the way for decisions and approvals
When to use Cowork vs Claude Code CLI:
- Cowork: Great for non-terminal users, quick file tasks, and when you want a visual interface
- Claude Code CLI: More powerful for developers — supports hooks, MCP servers, plugins, and full terminal integration
