Anthropic Brings Claude Cowork to Mobile, Web, and Cloud

Anthropic announced on Tuesday that its AI agent Claude Cowork is expanding from a desktop-only application to a multi-platform system accessible via web browsers, iOS, and Android. The update also moves task processing to the cloud by default, enabling users to start work on one device, continue on another, and have tasks proceed in the background even when devices are offline.

Rolling out in beta over the coming weeks, the expanded access begins with subscribers to Anthropic’s premium Max plan, with broader availability for other plans to follow. To mark the launch, Anthropic is extending doubled Cowork usage limits through August 5, 2026.

From Desktop to Everywhere

Claude Cowork launched in January 2026 as a desktop feature designed for non-technical users, automating multi-step workflows by pulling from files, calendars, email, messaging apps, and connected tools. Until now, users needed to keep their laptops open and active for tasks to complete, and Cowork could not operate across multiple devices with a single account.

According to Anthropic’s official blog post, three key changes take effect with this update. First, work now follows the user across devices: a task started at a desk can be checked from a phone and retrieved from any browser. Second, tasks continue running in the background after a laptop is closed, and scheduled tasks — such as “Monday’s client prep at 6 AM” — can execute autonomously without any device online. Third, Claude sends notifications to a user’s phone when decisions are needed, and nothing ships without human review and approval.

“Cowork is where you hand Claude a task, and it works across your files, calendar, email, messaging app, the web, and the other tools you connect until the job is done,” Anthropic said in its announcement.

Mike Krieger, Anthropic’s Chief Product Officer, noted on X/Twitter that chat and Cowork now share one home tab on web and desktop, with a unified sidebar, search, and shared access to Projects & Artifacts.

Desktop remains the full Cowork experience, with local file access and browser integration exclusive to the desktop app. Users who could not install a desktop app can now use Cowork via web or mobile for the first time.

The Work Around the Work

Alongside the platform expansion, Anthropic released data from an analysis of 1.2 million anonymized Cowork sessions conducted between May 11 and May 31, 2026, across more than 600,000 organizations. The findings challenge the common perception of AI agents as primarily coding tools.

As TechCrunch reported, more than 90% of Cowork sessions were unrelated to software development. The largest category was business process and operations at 33.4%, encompassing tasks like pulling scattered updates into reports, building onboarding checklists, and reconciling spreadsheets — work common in finance, HR, and administration. Content creation and copywriting followed at 16.4%, covering drafts, slide decks, social posts, and proposals. Software development accounted for just 8.7% of usage.

Anthropic described this as “the work around the work: rarely in anyone’s job description, but a large share of everyone’s week.”

“Our data suggests that people are using Claude Cowork to assemble and structure the information they can use to act on their expertise,” the company said.

Competitive Landscape and Implications

The expansion comes amid an intensifying race among AI companies to push beyond chatbots into agentic systems that complete multi-step tasks autonomously. OpenAI has made a similar move with Codex, which began as a software development tool but is increasingly used by non-developers for reports, spreadsheets, and presentations. Google and Microsoft have also launched rival agent products.

As ZDNET’s David Gewirtz observed, the cloud-based, scheduled, cross-device capabilities raise questions about how much traditional infrastructure knowledge workers will need going forward. “If I have Cowork and it runs autonomously in the cloud and on schedule, do I even need a dedicated server with OpenClaw anymore?” Gewirtz wrote.

The battleground is shifting from “who has the best chatbot” to “who owns the space where work gets done,” as NBC News noted. Claude has become a favorite among both technical and non-technical users, even as OpenAI’s ChatGPT remains the most well-known AI product.

Privacy and Permissions

As AI agents require broad system permissions to function effectively, Anthropic has implemented a permissions structure that frequently and repeatedly asks for user consent to perform specific tasks as Cowork operates. This addresses growing user concerns about agentic AI permissions, ensuring that nothing ships without user review and approval.

What’s Next

The rollout begins with Max plan subscribers in beta over the next several weeks, with expansion to Pro, Team, and Enterprise plans expected to follow. Anthropic also extended access to its Claude Fable 5 model for all paid plans through July 12. The doubled Cowork usage limits through August 5 provide an incentive for users to experiment with the new cloud-based, cross-platform capabilities.

As AI agents increasingly handle the administrative work that consumes a large share of knowledge workers’ weeks, the question is no longer whether these tools can code — it’s whether they can transform how all knowledge work gets done.
