Verdict: The "laptop umbilical cord" is officially cut. With the July 2026 update, Claude Co-work has evolved from a desktop-bound tool into a persistent, cloud-native workforce. By moving to web and mobile, you can now start a complex multi-hour task at your desk, close your laptop, and walk away—while Claude continues to work in the background and pings your smartphone only when it needs a final decision.
Last verified: July 9, 2026 Usage Limit Alert: Anthropic has doubled Co-work limits for Max, Pro, and Team plans through August 5, 2026. New Feature: Microsoft 365 "Write" tools are now live (Claude can now draft and send emails directly). Best for: Business operations, content creation, and data reconciliation (91.3% of current usage).
Why the Web and Mobile Move Changes Everything
Before this update, Claude Co-work was effectively "local-first." If your laptop went to sleep or you lost your internet connection, the task died. For small business owners, this meant sitting at a desk and "babysitting" the agent as it worked through spreadsheets or drafted decks.
As of July 7, 2026, Co-work sessions now run on Anthropic’s remote beta infrastructure. This provides three massive upgrades:
- Background Persistence: You can start a task (like "Research 50 prospects and draft personalized intro emails") and close your laptop immediately. The task runs in the cloud.
- Interactive Guidance: If Claude hits a fork in the road—such as an ambiguous client requirement—it stops and sends a notification to your phone. You redirect it mid-commute, and it picks back up.
- Unified Home: Your chat history, artifacts, and active Co-work sessions now share a single "Home" tab across all devices.
How to Set Up Claude Co-work on Every Device
To get started, you must be on a Max Plan (rolling out first) or a Pro/Team plan as the beta expands.
1. On the Web (claude.ai)
- Navigate: Go to the "Home" tab on claude.ai.
- Start Session: Look for the "Co-work" icon in the top right or the sidebar.
- Connectors: Ensure your Microsoft 365 or Google Workspace connectors are enabled.
- The Web Limitation: Note that the web version cannot access your local computer files or control your screen. It only interacts with connected cloud apps (SaaS) and the web.
2. On Mobile (iOS and Android)
- Download: Ensure you have the latest version of the Claude app from the App Store or Google Play.
- Access: Tap the sidebar (three lines) and select "Co-work."
- Monitor: You will see a list of "Active Sessions." Tapping one shows the real-time thought process and current step.
- Approve: When a "Decision Needed" badge appears, tap it to see the options Claude has proposed.
3. Desktop (The Power User Setup)
The Desktop app is still the only way to perform "Computer Use" tasks (clicking and typing across your local apps) or reading/writing local files. However, once a task is started on Desktop, you can still monitor and approve it from your phone.
The New Power Play: Microsoft 365 "Write" Integration
Coinciding with the mobile launch, Anthropic has upgraded the Microsoft 365 Connector. Claude no longer just reads your emails; it can now act on them.
| Capability | What Claude Can Now Do (July 2026) |
|---|---|
| Outlook | Draft, send, and organize emails; manage your calendar. |
| OneDrive/SharePoint | Create new documents and update existing ones. |
| Teams | Read-only (Writing is currently disabled for safety). |
Pro Tip: Combine this with the mobile update to have Claude draft your entire Monday morning email batch on Sunday night. You can review and "Send All" from your phone while having breakfast on Monday.
What this means for you
For small business owners, the "Work around the work"—the administrative burden that eats 40% of the week—is now delegatable. You are no longer the operator; you are the Director.
Start a session to "Reconcile June invoices against bank statements" at 5:00 PM. Close the laptop. Enjoy your evening. Check the finished report on your phone before bed. This is how you reclaim your time in the Era of the Autonomous Agent.
FAQ
Q: Does my phone need to stay on for the task to finish? **A: No. Once initiated, the task runs on Anthropic’s cloud servers. You only need your phone to receive updates or provide guidance.
Q: Can I use Co-work for free? **A: No. As of July 2026, Co-work remains a premium feature for Pro, Max, and Team users. Free users can access standard Claude chat but not the autonomous Co-work mode.
Q: Can Claude Co-work access my local files from the web version? **A: No. For security reasons, web and mobile sessions are sandboxed to cloud connectors only. To use local files, you must initiate the task from the Claude Desktop app.
Q: What is the "Judgment Request" feature? **A: This is a safety and accuracy gate. If Claude is unsure about an action (e.g., "Delete this file?"), it will pause and ask for your approval via a push notification.
