Anthropic is expanding Claude Cowork from the desktop app to mobile and web, giving its AI agent a broader role across the devices people already use for work. The change means Cowork is no longer tied to a single installed app, even though the desktop version still keeps important capabilities that the web version does not have.
What Is Changing For Claude Cowork
Claude Cowork has been available through the desktop app, but Anthropic is now rolling it out to mobile and web. Beta access will arrive gradually over the coming weeks, with Max subscribers first in line.
The practical change is continuity. A user can begin a task at a desk, look in on the work from a phone, and open the finished output from a browser elsewhere. That makes Cowork less dependent on the device where the work started.
Anthropic also says Claude keeps working in the background even if the laptop is closed or the phone is turned off. For an AI agent designed to complete longer tasks, that background behavior is central to the product. It lets the task continue without requiring the user to keep the original device active.
Human Approval Moves To The Phone
The mobile expansion also changes how users stay involved. When Claude reaches a step that needs a human decision, it can ask the user through a smartphone.
That keeps the person in the approval loop without forcing them to return to a desktop. The key point, according to Anthropic, is that nothing gets sent unless the user reviews and approves it first.
This matters because Cowork is not being described as a fully hands-off system. It is an agent that can continue work in the background, but it still pauses when a decision requires a person. The mobile layer makes those checkpoints easier to handle away from the main machine.
Most Cowork Use Is Not Coding
Anthropic says more than 90 percent of Cowork usage is not software work. That positions the product less as a coding-only assistant and more as an AI agent for general knowledge work.
The source highlights two large use categories: business operations and content creation. Together, those two areas account for roughly half of all usage, according to Anthropic.
Examples include work such as:
- reconciling quarterly spend
- drafting variance memos
- building client decks from call transcripts
Those examples show why mobile and web access are meaningful. Business operations and content workflows often involve checking progress, approving output, and reviewing finished material. Those actions do not always need the full desktop environment, even if some tasks still benefit from it.
Why The Desktop App Still Matters
The web version makes Cowork available to users who could not previously install the desktop app. But Anthropic says the desktop app remains essential for features that depend on the local machine.
Those desktop-only or desktop-dependent capabilities include reading and writing files in connected folders, local connectors and plugins, browser control through Claude in Chrome, and Computer Use. Computer Use is the mode where Claude clicks, types, and navigates directly on screen.
That creates a clear split. Web access lowers the barrier to trying Cowork, but it does not replace the desktop app for workflows that require local files, local integrations, or direct control of a computer interface.
For users, the difference is not simply about preference. It is about what kind of task Claude needs to complete. If the work depends on connected folders or on-screen actions, the desktop app still carries capabilities that web access does not.
Chat And Cowork Are Moving Closer
Anthropic is also changing how Chat and Cowork appear to users. On web and desktop, the two will share a single home screen going forward. Projects and artifacts will be available across platforms.
That points to a product experience where regular chat and agentic work sit closer together. The source notes that, aside from local file access missing from the web version, the distinction between Chat and Cowork is becoming less clear.
Anthropic is also extending its doubled Cowork usage limits through August 5 to mark the expansion. That gives users more room to test Cowork during the rollout period.
The broader direction is a more unified AI workspace. The source compares that direction with OpenAI plans to bring Codex and ChatGPT closer together, and notes that Mistral recently replaced Le Chat with Vibes, described as a more capable agentic coding environment. At the same time, ChatGPT and Claude are much larger brand names, which makes a similar shift harder for OpenAI and Anthropic.
For now, the important update is straightforward: Claude Cowork is moving beyond the desktop app. Mobile and web access make the AI agent easier to start, monitor, and approve across devices, while the desktop app remains the route for local machine capabilities.
