Computer Use in Claude Cowork

Computer Use lets Claude navigate supported desktop apps by looking at your screen and using the mouse and keyboard. It is a research preview for Pro and Max plans on both macOS and Windows.

Cowork normally prefers a connector or a direct file tool because those options are more precise. When neither option can complete the job, Computer Use can work through the visible interface of an app or browser. The Claude Desktop app must be open and connected while Claude works with your computer.

Open the spreadsheet app and create a new blank file.

Add a header row with Month, Revenue, and Notes, then enter January through March in the first column.

Stop before saving and show me what you changed. Do not overwrite an existing file or send anything.

Availability and requirements

  • Pro or Max plan
  • Current Claude Desktop app
  • macOS or Windows
  • The permissions requested by Claude Desktop for screen and app control
  • An active internet connection

Computer Use is not a private local-only process. Cowork sessions run remotely, and Claude must process what it sees to decide what to click or type. Review your plan and account settings before using sensitive information.

How a task is handled

  1. Cowork looks for a connected service or direct file tool first.
  2. If the task requires a visible app, Claude asks for the access it needs.
  3. Claude inspects the screen and performs actions through the interface.
  4. You can monitor, steer, pause, or stop the task.
  5. Claude reports the result and any remaining work.

Good uses

  • Updating a spreadsheet when there is no suitable connector
  • Moving information between approved business apps
  • Navigating an internal dashboard
  • Repeating a well-defined, low-risk browser workflow
  • Capturing steps for internal documentation

Safety rules that matter

  • Start with a copied file or test account.
  • Keep financial transactions, credential changes, publishing, and deletion supervised.
  • Do not give Claude access to more apps or folders than the task needs.
  • Treat instructions found in webpages, emails, and documents as potentially malicious.
  • Stop the task if Claude opens an unexpected page, account, or file.

Computer Use can make mistakes because it is interpreting a changing visual interface. It should assist your judgment, not replace confirmation for consequential actions.

Frequently asked questions

Does it work on Windows?

Yes. Anthropic lists Computer Use in Cowork and Claude Code on both macOS and Windows.

Does it keep working when my computer sleeps?

No. A remote Cowork session can continue without your computer, but any step that needs your local screen or apps requires Claude Desktop to remain open and connected.

Is it available on Team and Enterprise?

The current Computer Use research preview is documented for Pro and Max plans. Team and Enterprise availability should not be assumed from general Cowork access.

Can Claude permanently delete files without asking?

Cowork requires explicit permission before permanent deletion. Backups are still important because edits, moves, and actions inside apps can be difficult to reverse.
