Claude Cowork 向移动端和网页端开放

Claude Cowork is rolling out to mobile and web so your sessions and files go where you go, on any device. Beta access is rolling out over the next several weeks starting with Max users, with more plans to follow.

The work around the work

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. 

AI agents made their name writing code. But when we looked at how people use Claude Cowork, more than 90% of it wasn’t software development. Most of it was everyday knowledge work, and the largest categories were business operations and content creation: reconciling the quarter’s spend and drafting the variance memo, turning a folder of contracts into a renewals tracker with the risks flagged, building tomorrow’s client deck from call transcripts and pipeline data. Together, that’s roughly half of all usage. It's the work around the work: rarely in anyone’s job description, but a large share of everyone’s week.

What changes today

Everyone asks AI for answers. Handing it the work is different, and people keep giving Claude bigger jobs. Work like that doesn’t fit in one sitting. It accumulates overnight, between meetings, on the train. Until today, Cowork lived on your laptop, so the work stopped when you stepped away. Now it doesn’t. Three things change:

Your work follows you. Start a task at your desk, check on it from your phone, and pick up the finished output anywhere. 

Work continues in the background. Close the laptop and head to your meeting; Claude keeps going. Scheduled tasks now run with no device online. Set Monday’s client prep for 6 am: Claude works through the email threads, transcripts, and recent news, builds the briefing doc, and leaves the follow-up email drafted but unsent. Review it over coffee.

The decisions still come to you. When Claude reaches a call only you can make, it asks, and the question reaches your phone. You can redirect a draft mid-meeting and Claude keeps going, on the right path. Nothing ships until you’ve reviewed and approved it.

"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."

- Armmand Hosseini, Customer Success, Ramp

Desktop remains the place for deep work, and it’s the full Cowork experience, where Claude can also use your local files and browser. Users who couldn’t install a desktop app can now use Cowork too.

Two more changes you'll notice: on web and desktop, chat and Cowork now share one home, and your projects and artifacts live together across both. Delegating is now as easy as asking.

Getting started

On the web, start a Cowork session from the home screen at claude.ai. On mobile, open Cowork from the sidebar of the Claude app for iOS and Android. For the full experience, download the Claude desktop app. For what’s available on each surface, see the Help Center.

Start with something already on your plate: point Claude at the folder, the thread, or the half-finished deck, and describe what done looks like. To mark the launch, we’re extending doubled Cowork usage limits through August 5, so there’s plenty of room to try bigger tasks.
