Claude Cowork in the cloud: your tasks keep running with the laptop closed

Claude Cowork in the cloud means that, since October 6, 2026, new tasks on the Pro and Max plans stopped running on your computer and moved to Anthropic's servers, across web, mobile and desktop. You close the laptop and the task keeps going. There is one key exception: if the task uses local files, local connectors, the browser with Chrome or computer control, the desktop app has to stay open and connected.

What changed and when

It happened in three steps, and the last one is this week. Cowork started earlier this year as a Claude mode for long tasks on your computer. On September 16, 2026 Anthropic merged it into chat: now it is simply Claude, you ask for something and it decides whether that is an answer or a task. And on October 6, new tasks moved to the cloud. Tasks you had already started finish where they were.

How it works inside

Your task runs in a cloud session, like an assistant who stays at the office after you have left. The session lives in your account, not on your machine, so you open it the same way from the browser, your phone or the desktop app. Scheduled tasks run up there too: you say "every Monday, start the report" and on Monday it starts on its own.

Two more details. Cloud sessions use the memory from your earlier conversations; local ones did not. And the files Claude hands you are saved to your account.

Why it matters: work about work

Asana's Anatomy of Work Index, a survey of 9,615 knowledge workers, reports that 58% of their day goes to work about work: searching for information, switching apps, following up and summarizing. Skilled work is 33% and strategic work, only 9%. It is a survey, not a stopwatch, but that 58% is exactly the repeatable part.

The walkthrough of a task, start to finish

1. You open Claude in the browser or on your phone and type what you want, for example "go through my supplier emails and give me a summary".
2. You connect Gmail and, if you like, Slack or your calendar.
3. Claude works in the cloud and asks for your approval before important actions.
4. You see the result and correct it: shorter, urgent items first.
5. You say "schedule it every Monday at seven".
6. On Monday the result is already waiting, and you haven't opened anything.

The math on hours

This math is WAiBOT's, not Anthropic's. If your weekly report takes 45 minutes, over 52 weeks that is 2,340 minutes: 39 hours a year. If Claude drafts it and you only review it in 10 minutes, you spend 520: almost nine hours. You get about 30 hours back. With a one-hour report it would be 43, and with three tasks like that, about 90 hours a year: more than eleven eight-hour workdays. The math does not depend on the model being a genius, but on the task repeating and on you reviewing the result.

Three proposed cases

These are flows proposed by WAiBOT, not cases published by Anthropic. What is official is that scheduled tasks run in the cloud and that those using only connectors, like Gmail or Slack, do not need your computer turned on.

• The online store owner. Every Monday at seven, Claude checks Gmail for supplier emails and weekend returns, and posts a summary in Slack with the urgent items on top. She reads it from her phone without opening the laptop.
• The independent consultant with six clients. Every Sunday night, Claude reads her calendar and the pending emails, and builds her Monday plan. It also drafts the most repeated replies for her to approve: if a client wrote something sensitive, she sees it first, because Claude only proposes.
• The coordinator of an eight-person team. Every Friday at five, Claude reads the team's Slack channel and summarizes what moved forward, what is blocked and who is waiting on whom. He fixes it in five minutes and sends it to management. The valuable part is not the writing: it is that nobody has to remember to do it.

The limit: when it still needs your computer

The mistake almost everyone will make is scheduling a task that uses local files and assuming it runs on its own. Cloud tasks do not touch your computer's folders by themselves. For local files, local connectors, the browser with Chrome or computer control, the desktop app has to stay open and connected. If your Mac goes to sleep, that run gets skipped. There is a setting for those tasks, require this computer, but then you depend on it. And a session does not switch from local to cloud midway: you start a new one.

What gets lost and what is missing

In the cloud, the files Claude hands you are saved, but the working files it does not hand you are not. You can find past sessions by title, not yet by full text. With many files, or very large ones, processing can run slower. On web and mobile it is still in beta for Pro, Max and Team. Anthropic announced it is removing the "only on your computer" option, but its help page still mentions a toggle in settings, and the rollout is gradual, so check what you see.

The objection: does Anthropic see my files?

The originals stay on your computer, but their contents are sent and processed in the cloud when the task needs them. According to an outside analysis, memories can survive even if you delete the conversation, deleted conversations leave the systems within 30 days, and ones flagged for safety can be kept up to two years. Those periods come from that analysis, not from Anthropic. There is also a real risk: a malicious page or document can try to give orders to the agent. Before connecting anything, review which memories you have saved in settings, use dedicated folders and require manual approval for anything important.

Who it is not for yet

Anyone handling regulated or confidential data, like medical records, privileged legal information or trade secrets, without a clear company policy. Anyone who needs a task to use local files with the laptop off, because that still does not happen. And anyone expecting zero review: it is an assistant that gets you a head start on the draft, not an employee you delegate to without looking.

The precedent and the comparison with Codex Cloud

The video compares it to email: when Gmail arrived in 2004, plenty of people distrusted leaving years of mail on a Google server, and today nobody thinks twice. That is an analysis, not a fact: moving something to the cloud costs trust at first and later becomes habit. This week, OpenAI's Codex Cloud took the work of programmers to the cloud; Claude makes the equivalent move for everyone else: email, reports and follow-ups.

How to apply it in your business?

The six-step recipe for your first cloud task:

1. Pick the task you repeat most, one that ends in text, not in an irreversible action.
2. Connect only what it needs, Gmail, Slack or calendar, and nothing more.
3. Write what you want, in what format, and what it must not do.
4. Run it once by hand and correct it.
5. Schedule it.
6. The first week, review every result and measure how many minutes it saved you.

Model task: every Monday at seven, summarize the urgent items in my email in ten lines, without replying to anything.

Frequently asked questions

Since when does Claude Cowork run in the cloud?

Since October 6, 2026, for new tasks on the Pro and Max plans. Tasks you had already started finish where they were.

Can I close the laptop and keep the task running?

Yes, if the task only uses the cloud and connectors like Gmail or Slack. If it uses local files, local connectors, Chrome or computer control, the desktop app must be open and connected.

How many hours does it save?

It depends on your task. For a 45-minute weekly report you review in 10, it is about 30 hours a year, but that is WAiBOT's math, not Anthropic's.

Does Anthropic see my files?

The originals stay on your computer, but their contents are processed in the cloud when the task needs them. The 30-day and up-to-two-year retention periods come from an outside analysis.

Conclusion

Claude Cowork in the cloud means your tasks no longer depend on your laptop being awake, except when they touch local files. Start with the task you repeat most every week, check that it does not need your computer and measure how much time you get back.
