Claude Cowork on Windows, Mac, Linux, and Chrome: The Full Picture
Claude Cowork runs inside the Claude desktop app, and the desktop app is available on Windows, macOS, and Linux (in beta) — so whichever operating system you're on, you're covered. The one place people get tripped up is Chrome: there's no separate "Cowork extension," and this guide clears that up along with what each platform actually needs.
TL;DR
Claude Cowork isn't a separate download — it's a mode inside the Claude desktop app, which runs natively on Windows 10+, macOS 11+ (Big Sur or later), and Linux (currently in beta, Ubuntu 22.04+ or Debian 12+, x64 or arm64). Get it from claude.com/download (opens in a new tab), sign in with a paid Claude plan, and open Cowork mode. There is no dedicated "Claude Cowork Chrome extension" — what exists is a separate, related tool called Claude for Chrome, a browser extension for working alongside your open tabs, which pairs well with Cowork but isn't the same product. Setup takes minutes on every platform; the free Claude Cowork course covers what to actually do once it's installed.
Where Claude Cowork actually runs
One thing worth being precise about before the platform-by-platform breakdown: Cowork is not its own app. It's a mode within the Claude desktop app — the same application you'd use for regular Claude chat, with Cowork as an additional workspace for multi-step, multi-file tasks. So "getting Cowork" on any platform means the same three steps everywhere:
- Install the Claude desktop app for your operating system.
- Sign in with a paid Claude plan (Cowork isn't included on the free plan — see pricing).
- Open Cowork mode and point it at a folder on your machine.
The differences between platforms are in installation and system requirements, not in what Cowork can do once it's running.
Claude Cowork for Windows
The Claude desktop app supports Windows 10 or higher. Download the Windows installer from claude.com/download (opens in a new tab), run it, and sign in with your Claude account. Once installed, Cowork works the same as on any other platform — it reads and writes files in a folder you grant it access to on your Windows machine.
If you've only used Claude through the browser at claude.ai, the desktop app is a separate install — the browser version doesn't include Cowork.
Claude Cowork for Mac
macOS support requires macOS 11 (Big Sur) or later — which covers the overwhelming majority of Macs still in regular use. Download the macOS build from claude.com/download (opens in a new tab), drag it into Applications like any Mac app, and sign in. Cowork behaves identically to the Windows version; the only difference is the installer.
Claude Cowork for Linux
Linux support is real but currently in beta, covering Ubuntu 22.04 LTS+ and Debian 12 (bookworm)+ on both x64 and arm64. Rather than a one-time .deb download, Anthropic distributes the Linux build through its own apt repository, so once it's set up, updates arrive the normal way through your system's package manager rather than requiring a manual re-download each time.
Because it's beta, treat it with the caution you'd give any beta release on a machine you rely on: expect it to work well for most use cases, but check claude.com/download (opens in a new tab) for the current setup instructions, since beta installation steps are the most likely thing on this page to change.
Is there a Claude Cowork Chrome extension?
No — and this is worth stating plainly since it's a common search. There is no standalone "Claude Cowork" extension in the Chrome Web Store. Cowork lives inside the desktop app, full stop.
What does exist is a separate, genuinely useful tool: Claude for Chrome, a browser extension available on paid Claude plans. It opens Claude in a side panel while you browse, and lets Claude read a page, extract information, and work across multiple open tabs — a different capability aimed at browser-based research and web tasks rather than local file management.
The two complement each other well: Claude for Chrome can gather information from the web while you're browsing, and Cowork can turn what you've gathered into a finished document, spreadsheet, or report on your desktop. They're not the same product, and neither replaces the other — but if you install both, you cover browser-based research and local file work with the same underlying AI.
Which platform should you actually use?
Whichever one you're already on. Cowork's capability doesn't change by operating system — a Windows user, a Mac user, and a Linux user all get the same file-organizing, document-drafting, and research-synthesis functionality once the desktop app is installed and signed in. The only real consideration is that Cowork works with files on the specific machine it's installed on; if you work across multiple computers, you'll need the desktop app (and Cowork access) set up on each one you plan to use it from, since it isn't a synced cloud workspace the way regular Claude chat history is.
Where to verify before you rely on it
A few honest notes regardless of platform:
- Linux is beta. Expect occasional rough edges compared to the more mature Windows and Mac builds, and check current documentation before deploying it on a machine you can't afford downtime on.
- System requirements and installers change. Anthropic updates the desktop app regularly; the version numbers and exact requirements above are accurate as of this writing but are the most likely detail on this page to go stale — claude.com/download (opens in a new tab) is the source of truth.
- Cowork needs folder access to work, by design. You're granting it access to read and write files in a folder you choose — normal for how it operates, but worth being deliberate about which folder you point it at, especially with sensitive client or financial data.
Getting started, whatever your OS
- Confirm you have a paid Claude plan (Cowork isn't on the free tier).
- Download the desktop app for your platform from claude.com/download (opens in a new tab).
- Sign in and open Cowork mode.
- Point it at a real folder and try one genuine task — organizing files or assembling a draft from a few documents is the easiest first win.
Frequently asked questions
Does Claude Cowork work on Windows?
Yes. The Claude desktop app, which includes Cowork, supports Windows 10 and higher. Download it from claude.com/download, sign in with a paid Claude plan, and open Cowork mode — it works identically to the Mac and Linux versions.
Does Claude Cowork work on Mac?
Yes, on macOS 11 (Big Sur) or later. Download the macOS build of the Claude desktop app, install it like any other Mac application, and sign in with a paid plan to access Cowork.
Is Claude Cowork available on Linux?
Yes, currently in beta, supporting Ubuntu 22.04 LTS+ and Debian 12 (bookworm)+ on x64 and arm64. Anthropic distributes it through an apt repository so updates arrive through your normal package manager. Being beta, expect it to be slightly less polished than the Windows and Mac builds.
Is there a Claude Cowork Chrome extension?
No, not as a standalone product. Cowork only runs inside the Claude desktop app. What does exist is Claude for Chrome, a separate browser extension for working with open tabs and web pages, which pairs well with Cowork but is a different tool with a different purpose.
Do I need to install Claude Cowork separately from the Claude desktop app?
No. Cowork isn't a separate download — it's a mode within the Claude desktop app you access once you're signed in with a paid plan. Installing the desktop app for your platform is the only installation step.
Get it running, then learn it
Installing Cowork takes a few minutes on any platform — the real learning curve is knowing how to hand it work well. The free Claude Cowork course covers the actual workflows and prompts, built for business owners and operators rather than developers. It's a free download.
