Claude Cowork Is Now on Mobile and Web: What Professionals Need to Know

TL;DR. Claude Cowork expanded from desktop-only to mobile and web on July 7, 2026, rolling out first to Max subscribers. Tasks can now run in the background even when your laptop is closed — with a phone prompt if Claude needs your sign-off. The web version doesn't access local files or control your computer; those stay desktop-only.

Claude Cowork launched in January 2026 as a desktop-only agent — something you ran on Mac or Windows, with the app open. As of July 7, 2026, that changed: Anthropic began rolling out Cowork to mobile (iOS and Android) and the web, starting with Max subscribers.

This is not a minor feature addition. It changes where Cowork fits in a workday and which workflows are practical to run on it.

The three things that actually changed

1. Mobile access. Cowork is now on iOS and Android. You can start a task from your desk, check on it from your phone, and review what it produced wherever you are.

2. Web access. You can open Cowork in a browser — no desktop app install needed. That matters for people who work across multiple devices, travel with a tablet, or work in environments where desktop installs are restricted.

3. Background execution that survives a closed device. This is the most significant change. Cowork tasks can now run in the background even when your laptop is off. When Claude reaches a decision point that requires human input, it sends an approval prompt to your smartphone rather than pausing the task. You handle it from your phone; the task continues.

Previously, a Cowork task paused if you closed the laptop. Now it keeps running. That rewrites which workflows are practical — especially anything that should complete overnight or during time away from your desk.

What is still desktop-only

The web and mobile versions of Cowork are not identical to the desktop experience. Two capabilities remain desktop-only:

• Local file and folder access. Cowork on desktop can read and write files directly in your computer's folders. The web version has no path to your local drive. This affects any workflow that uses local files as inputs or outputs.
• Computer control. On desktop, Cowork can control your computer — opening apps, navigating browsers, filling forms — as a person would. That feature doesn't exist on web or mobile.

For cloud-based workflows — anything routed through Google Drive, Slack, Gmail, or web-based tools via connectors — the web and mobile versions work fully. For workflows that touch local files or require computer control, the desktop app is still required.

What the usage data tells us

Alongside the launch, Anthropic released figures from 1.2 million Cowork sessions: over 90% of activity is non-coding work. Business operations — reporting, checklists, spreadsheets — account for about 33% of sessions. Content creation (drafts, proposals, presentations) is another 16%. Software development is 9%.

That usage split is consistent with how Cowork has been positioned: less coding tool, more knowledge-work agent. The mobile and web expansion follows from it — if the primary use is business operations and content work, cross-device access matters more than terminal integration.

Who should pay attention now

Max subscribers: check your Claude app for web and mobile access. It's a rolling beta starting July 7, 2026, so it may not be visible immediately.

Pro subscribers: the rollout started with Max. No public timeline has been confirmed for Pro. The desktop app continues to work fully in the meantime.

Anyone with scheduled Cowork workflows: the background execution change is the thing worth testing first. Any task that currently requires your laptop to stay on is a candidate for the new setup once you have web/mobile access.

People who've been waiting on platform fit: if the desktop-only requirement was what kept you from building Cowork into a workflow, that constraint is loosening. The web version covers cloud-based work; the mobile app gives you status and approval access on the go.

What to watch

The web version's lack of local file access is the main limitation. For some professionals — accountants running reconciliations on local spreadsheets, healthcare workers using local note templates — desktop will remain the primary surface. For others whose work lives in the cloud, the new web access may be sufficient.

Anthropic hasn't announced pricing changes or plan-level changes alongside this expansion. The doubled usage limits running through August 5 look like a beta-period incentive rather than a permanent change.

The broader pattern: Cowork started as a desktop tool for knowledge workers. What launched in July 2026 is a cross-platform agent that runs when you're not at a desk and routes decisions to your phone. That's a different product shape — and one with implications for how professionals build their workflows around it.
