Anthropic launched Claude Cowork on mobile devices and in the browser

On July 8, 2026, Anthropic opened access to the Claude Cowork collaborative work platform for mobile devices and browsers — for the first time since its launch. Until now, the tool was available exclusively in desktop applications for macOS and Windows.

What is Claude Cowork and what has changed

Claude Cowork is not just a chat with a language model, but a workspace where multiple AI agents can perform tasks in parallel: one searches for information, another writes code, a third analyzes documents. The user observes progress in real time, sets tasks, and intervenes when necessary.

Until now, only those with a desktop application open could use this. Now Cowork is available via iOS, Android, and any browser.

Key details of the expansion:

• Mobile and web version launch date — July 8, 2026
• Max plan subscribers get access first
• Users of other plans — "in the coming weeks"
• New platforms: iOS, Android, web browser (in addition to macOS and Windows)
• Sessions now work in the cloud by default and sync across devices

The latter is a fundamental technical change. Previously, Cowork sessions existed locally; now a session started on a laptop can be continued from a smartphone without loss of context, tasks, or intermediate agent results.

What remains desktop-only

Anthropric is explicit: the "full experience" of Cowork remains in the desktop application. This primarily concerns access to local files — a feature that technically requires direct connection to the device's file system.

Scenarios where a Claude agent works with files on your computer — processing documents from local folders, reading code repositories, accessing local databases — will still require a desktop application. Mobile and web versions are optimal for tasks performed entirely in the cloud: information search, text writing, working with online services.

Why this matters for working with AI agents

Cowork's release on mobile platforms and browsers removes a key limitation — binding to a specific work computer. This is especially critical for long-term tasks: you can launch a set of agents in the morning from a laptop and check the results in the evening from your phone on the go.

Moving sessions to the cloud opens another scenario: Cowork tasks can continue in the background even when the device from which they were launched is off or unavailable. This brings Cowork closer to the model of "agent works autonomously, you check the results."

The step also fits into the broader competition between AI labs for mobile audience. OpenAI is actively developing ChatGPT applications for iOS and Android, Google is embedding Gemini directly into the operating system. Anthropic has until recently remained primarily a desktop company — mobile Cowork closes part of this gap.

What this means

Mobile and web access translate Claude Cowork from a niche tool for users with a work computer into a cross-platform platform for managing AI agents. Anthropic is betting that interaction with agents should be available anywhere and from any device — not only where a laptop is located.
