Claude Can Now Use Your Computer: Computer Use in Cowork & Claude Code Explained (2026)

Claude Can Now Use Your Computer: Everything You Need to Know

Anthropic dropped a significant update today. Claude can now control your Mac — opening apps, clicking through browsers, filling in spreadsheets, running developer tools — anything you would do sitting at your desk.

The feature is live right now as a research preview in Claude Cowork and Claude Code, available to Claude Pro and Max subscribers on macOS. Here is a full breakdown of how it works, what it can do, and what to watch out for.

You can now enable Claude to use your computer to complete tasks.

It opens your apps, navigates your browser, fills in spreadsheets—anything you'd do sitting at your desk.

What Is Claude Computer Use?

Until today, Claude could chat, write code, and use integrations you explicitly set up — but it could not actually do things on your computer. It could tell you how to do something, but not do it for you.

That changes with this update. When Claude lacks a direct connector to a service it needs, it can now fall back to controlling your screen itself — navigating your browser, clicking buttons, opening applications, filling forms, and running tools — exactly as you would.

The key phrase from Anthropic's announcement is "no setup required." You do not configure Claude to understand a specific app. It reads your screen and figures it out.

How Claude Decides What to Do With Your Computer

Claude follows a clear priority order when executing a task, and it does not jump straight to clicking around your screen:

1. Connectors first. If you have an integration set up for the service Claude needs — Slack, Google Calendar, Google Drive — it uses that. Direct integrations are faster and more precise than screen navigation.
2. Browser second. If a connector is not available, Claude can control your browser to reach the web-based version of a tool.
3. Full screen control last. Only when neither of the above works will Claude resort to controlling your mouse, keyboard, and screen directly.

This hierarchy matters. It means Claude is not blindly clicking around your desktop. It reaches for the most reliable tool first and only uses screen control when it is the best remaining option.

What Can Claude Actually Do on Your Mac?

According to Anthropic's announcement, the current capabilities include:

• Opening and navigating applications — any app on your Mac
• Browser control — navigating websites, clicking links, filling forms, running searches
• File management — opening, editing, and saving documents
• Developer tools — running terminals, IDE operations, test runners
• Spreadsheet work — filling data, applying formulas
• Anything you can do at your keyboard — if you can do it manually, Claude can attempt it

For developers using Claude Code, this means Claude can now make changes in your IDE, run tests, and push a pull request — without you in the loop at every step.

For knowledge workers using Cowork, it means delegating tasks like pulling data from a dashboard into a weekly report, or filling in a spreadsheet from a browser-based tool.

Dispatch: Assign Tasks From Your Phone

Computer use lands alongside a feature called Dispatch, which was released last week and is now also available in Claude Code.

Dispatch creates one continuous conversation with Claude that follows you across devices. You assign a task from your phone, walk away, and Claude does the work on your Mac. When you come back, the finished output is waiting.

The combination of Dispatch and computer use is what makes this genuinely useful in practice. Examples Anthropic highlighted:

• Morning briefings: Tell Claude once to check your emails every morning and compile a briefing. It runs while you are on the train. The briefing is ready when you sit down.
• Dev workflows: Assign a pull request from your phone. Claude makes the changes in your IDE, runs the tests, and puts up the PR.
• Recurring reports: Schedule Claude to pull weekly metrics from an analytics dashboard and drop them into your report template every Friday.

To use Dispatch, you need both the Claude desktop and mobile apps at their latest versions, with your devices paired in settings.

Security and Safeguards

Anthropic built several safeguards into computer use, though they are clear that this is still an early preview with real limitations.

Permission gating. Claude always asks before accessing a new application. You see what it intends to do and can stop it at any point.

Prompt injection detection. When Claude is navigating the web or reading documents, malicious content on a page could theoretically try to redirect Claude's actions. Anthropic says they scan model activations in real time to detect prompt injection attempts.

Isolated VM in Cowork. Cowork already ran Claude inside an isolated virtual machine. Computer use within Cowork operates inside that same VM boundary, meaning Claude only touches files and apps you explicitly grant it access to.

Some apps are off-limits by default. Certain sensitive application categories are blocked from computer use unless you specifically enable them.

Despite these safeguards, Anthropic explicitly recommends not using this feature with sensitive data at this stage. Complex tasks sometimes need a second try, and screen navigation is slower and less reliable than a direct integration. They are sharing the preview early to learn from real-world use.

Who Can Use It and How to Get Started

Eligibility:

• Claude Pro ($20/month) — included
• Claude Max ($100–$200/month) — included
• Team and Enterprise — check with your admin; not captured in audit logs yet
• Free plan — not available

Platform:

• macOS only (for now)
• Claude Desktop app required — download at claude.com/download

Steps to enable:

1. Open the Claude Desktop app and update to the latest version
2. Go to Cowork or Claude Code in the sidebar
3. Computer use is available as a toggle within the session — enable it when you want Claude to be able to control your screen
4. Start with a simple task: "Open Safari and search for the latest AI news, then summarize what you find in a new document"
5. Grant or deny the permission prompts Claude shows before each new action

For Dispatch (phone-to-desktop tasks):

1. Install the Claude mobile app and update to the latest version
2. Go to Settings on desktop and pair your mobile device
3. Assign tasks from your phone — your desktop needs to be awake and the app open

Practical Things to Try First

If you want to test computer use without touching anything critical, here are safe starting points:

For knowledge workers:

• "Open my Downloads folder in Finder and organize the files by type into subfolders"
• "Go to [website], copy the pricing table, and paste it into a new spreadsheet"
• "Open my calendar app and give me a summary of this week's meetings"

For developers:

• "Open Terminal, run the test suite, and show me which tests failed"
• "In VS Code, find every file that imports the deprecated axios library and list them"
• "Push my current branch to GitHub after running lint"

With Dispatch:

• "Every weekday at 8am, check my email for anything urgent and send me a summary on my phone"
• "When I message you 'start PR', open VS Code, run tests, and push to the current branch"

Computer Use vs. Other AI Agents in 2026

Claude is not the only AI with computer use capabilities in 2026. OpenAI's Codex has similar screen control features, and Perplexity Computer and Meta's Manus are also active in the space.

What sets Claude's implementation apart, according to Anthropic:

• The connector-first approach — Claude reaches for precise integrations before falling back to screen control, which reduces errors
• The VM isolation in Cowork — file and app access is sandboxed in a way that other tools do not offer by default
• The Dispatch integration — phone-to-desktop task handoff is built in from day one, not an afterthought

The honest caveat is that all computer use features — across every vendor — are still early. Screen navigation is inherently slower and more fragile than a well-built API integration. The real value right now is in the gap: the long tail of apps and tools that will never have a dedicated Claude connector, where screen control is the only path forward.

What Comes Next

Anthropic framed this launch explicitly as a research preview — they want feedback on where it works and where it falls short. Based on the Cowork preview trajectory (which launched for Max subscribers in January 2026 and expanded to Pro in February), expect computer use to roll out more broadly over the coming weeks.

Things likely coming based on the current limitations:

• Windows support — currently macOS only; Cowork added Windows support in February 2026, so computer use likely follows the same path
• More granular permission controls — currently app-level; finer controls per-action are likely
• Expanded default app access — some apps are off by default; that list will evolve
• Better handling of complex multi-step tasks — the current preview sometimes needs a retry on longer workflows

If you try it, use the feedback button in the app. Anthropic has consistently iterated fastest on Cowork and Claude Code based on direct user reports.
