TLDR
Anthropic rolled out Claude Cowork to web, iOS and Android in beta for Max subscribers on 7 July 2026, extending a feature that had been desktop-only. Sessions run remotely on Anthropic's servers, so tasks keep executing in the background even when a user's device is offline or switched off. The expansion reveals a striking usage pattern: more than 90% of Cowork sessions are everyday knowledge work such as business operations and content creation, with software development accounting for less than 10%. The move positions Claude Cowork against OpenAI's Codex controller and Microsoft's Copilot as AI agent platforms push beyond coding into general office workflows.
KEY TAKEAWAYS
Web and mobile beta lands for Max subscribers
Anthropic launched Claude Cowork on web, iOS and Android in beta on 7 July 2026, opening a feature that had been confined to the desktop app to a far wider set of surfaces.verifiedVerified Source: claude.com[1] The rollout began with Max plan subscribers, with the company signalling that additional plans would follow over the coming weeks.[2]
Anthropic's product team said: "Claude Cowork is in beta on web and mobile, and rolling out over the next several weeks starting with the Max plan, with more plans to follow."[2] Anthropic also doubled Cowork usage limits through 5 August 2026 and merged chat and Cowork into a unified home tab on web and desktop, with projects and artefacts accessible from either mode.[1]
Remote sessions, local sessions and what each can do
Cowork sessions run remotely on Anthropic's servers, so work continues in the background when a device goes offline, scheduled tasks execute without any device being active, and session state and files sync across desktop, web and mobile.verifiedVerified Source: claude.com[1] That server-side execution model is what makes mobile practical: the phone becomes a window into a running process rather than the machine powering it.
Users start Cowork on web by selecting "Cowork" in the chat box at claude.ai, on mobile through the sidebar in the latest Claude app for iOS or Android, and on desktop via the Claude Desktop app.[2] Desktop remains the only surface with full local file and browser access, including integration with the Claude in Chrome extension and direct interaction with the local machine.[2]
Armmand Hosseini, who works in customer success at Ramp, described the cross-device continuity in practice. "I built a dashboard to track my clients while traveling. I started on my laptop and picked the session up on my phone while waiting for my bag to come out. It just held the thread," Hosseini said.[1]
Coding is a footnote; office work is the story
More than 90% of Cowork sessions are everyday knowledge work, with business operations and content creation the largest categories, and software development accounting for less than 10% of usage.verifiedVerified Source: claude.com[1] That ratio reshapes how the product should be read: Cowork is not a coding agent that occasionally helps with other tasks. It is an office automation tool that happens to be able to write code.
The categories dominating usage point toward finance, HR and administration workflows, the repetitive, multi-step operational work that consumes large portions of knowledge workers' days. Anthropic's own framing describes Cowork as targeting "the work around the work", offloading routine tasks to the agent and reserving human involvement for decision points where judgement matters.
Where Cowork sits in the broader agent race
The expansion intensifies competition in an agent market that has moved well beyond its origins in developer tooling. Anthropic is positioning Claude Cowork directly against OpenAI's Codex controller inside ChatGPT and Microsoft's Copilot, both of which have been extending their own autonomous task execution capabilities into general business workflows.[1]
The server-side session model Anthropic has chosen is a concrete technical differentiator. Competing agent implementations that rely on local execution lose state when a device sleeps or loses connectivity; Anthropic's remote execution keeps the agent working regardless of what the user's hardware does, which is a meaningful advantage for long-running background tasks.
Who it suits and what it still cannot do
The primary audience, as the usage data makes clear, is nontechnical knowledge workers rather than software developers. Desktop remains the only Cowork surface with full local file access, browser integration via the Claude in Chrome extension, and direct computer interaction, capabilities that require local hardware access unavailable to remote sessions.[2]
Anthropic has not disclosed a timeline for bringing local-session capabilities to web or mobile, nor confirmed which additional plans beyond Max will gain access and when. The doubled usage limits expire on 5 August 2026.[1]
