Cowork

Last verified: 21 April 2026 | Applies to: Pro, Max, Team, Enterprise

Cowork is Claude that can act autonomously. Now generally available (GA since 9 April 2026), it runs in Claude Desktop on macOS (Apple Silicon only) and Windows (x64 only) and gives Claude the ability to read files, browse the web, execute code, and take multi-step actions on your behalf. The GA release added RBAC, spend limits, analytics, OpenTelemetry support, a Zoom MCP connector, and granular connector permissions. Cowork now defaults to Opus 4.7, the current flagship model. The gap between “Claude helped me think through this” and “Claude actually did this” is Cowork.

Cowork gives Claude access to a folder on your computer. From there, Claude can:

  • Read and create files: process documents, build spreadsheets, organise folders
  • Browse the web: research topics, pull data from websites, verify information
  • Execute code: run scripts, process data, build automations
  • Use plugins: install domain-specific plugins for finance, legal, sales, and more
  • Queue multiple tasks: run several jobs in parallel
  • Create designs and prototypes: use Claude Design (research preview) to generate designs, slides, one-pagers, and prototypes from text descriptions. Powered by Opus 4.7 with native Canva integration. See Claude Design.
  • Follow instructions: set global or folder-specific instructions that persist across sessions
  • Run scheduled tasks: use the /schedule command to define a task once and set a cadence (hourly, daily, weekly, weekdays only, or on demand). Claude runs it automatically on the schedule you set. Available on all paid plans.
  • Control your screen: when no connector exists for a task, Claude can fall back to native screen control (see Computer Use below)
  • Send tasks from your phone: use Dispatch to send tasks to your desktop Cowork session from mobile (see Dispatch below)
  • Persistent projects: link folders, set custom instructions, and enable per-project memory (see Projects below)

Global instructions apply to every Cowork session. Folder instructions apply only when Claude is working in a specific folder. This is the simplest way to customise Claude’s behaviour without building a plugin.

If you have never used a tool like Cowork before, this section is for you. No code, no terminal, no developer experience required.

What Cowork looks like when you open it. You will see a chat interface on one side and a file browser on the other. The file browser shows the folder you selected. You type instructions in plain English, and Claude reads your files, creates new ones, and takes actions on your behalf. It looks and feels like a chat conversation, except Claude can actually do things on your computer.

Your first three tasks to try:

  1. Organise a folder. Point Cowork at your Downloads folder (or any cluttered folder) and say: “Sort these files into subfolders by type: documents, spreadsheets, images, and other.” Claude reads the file names, creates the subfolders, and moves everything. You can review before confirming.
  2. Summarise a set of documents. Drop a few PDFs or Word files into a folder, point Cowork at it, and say: “Read all the documents in this folder and give me a one-paragraph summary of each.” Claude reads every file and produces a summary you can scan in 30 seconds.
  3. Generate a report from a CSV. If you have any spreadsheet data exported as a CSV, say: “Read this CSV and create a summary report. Include totals, averages, and any trends you notice. Save it as a new file called summary.md.” Claude reads the data, runs the analysis, and saves the output.

Common fears addressed:

  • “Will it break my files?” Cowork works within the folder you select. It can read and create files, but it asks for confirmation before modifying or deleting anything. If you are cautious, tell Claude: “Do not modify any existing files. Only create new ones.” It will follow that instruction.
  • “Do I need to know code?” No. You type plain English instructions. Claude may write and run code behind the scenes to accomplish your task (for example, processing a CSV), but you never need to see or write code yourself.
  • “What if I give it a bad instruction?” Claude will ask for clarification rather than guessing. If something is ambiguous, it pauses and checks. You are always in control.

Cowork for non-developers: The majority of operators using Cowork are not developers. The most popular tasks are file organisation, document summarisation, report generation, data cleaning, and email drafting. If you can describe what you want done in a sentence or two, Cowork can do it.

  1. Open Claude Desktop (macOS with Apple Silicon, or Windows x64)
  2. Click the Cowork tab
  3. Select a folder for Claude to work in
  4. Start a conversation: Claude can now read and modify files in that folder

To install plugins: Visit claude.com/plugins or use the plugin interface in the Cowork tab to browse and install.

To set instructions: Create a file called CLAUDE.md in any folder. Cowork reads this automatically when working in that directory.

Processing documents: “Read all the invoices in this folder, extract the totals, and create a summary spreadsheet.”

Research and reporting: “Research our top 5 competitors’ pricing pages, compare their plans to ours, and write a competitive analysis.”

Building plugins: “Create a plugin for our weekly ops reporting workflow”: Claude builds the folder structure, manifest, and skills files.

File organisation: “Go through these 200 support tickets exported as CSVs, categorise them by issue type, and create a summary with trends.”

Research preview. macOS (Apple Silicon) and Windows (x64) since 3 April 2026. Available on Pro and Max.

    A[You give Claude a task] --> B{Connector available?}
    B -->|Yes| C[Use connector]
    B -->|No| D[Fall back to screen control]
    C --> E[Task completed]
    D --> F[Claude sees your screen]
    F --> G[Clicks, types, opens apps]
    G --> E

Claude can now see and control your screen, clicking, typing, scrolling, and opening applications. When no connector exists for a task (for example, a niche web app without an integration), Claude falls back to native screen control rather than stopping.

This is a research preview: it works, but there are important caveats:

  • macOS (Apple Silicon, M1+) and Windows (x64). As of 3 April 2026, Computer Use is available on both platforms. Windows support works in both Cowork and Claude Code.
  • Pro and Max subscribers only. Not available on Team or Enterprise plans.
  • Not recommended for sensitive data. Claude can see everything on your screen while screen control is active. Avoid using it when passwords, financial credentials, or confidential information is visible.
  • Different from the API computer use beta, which runs in a sandboxed VM using screenshots. Cowork’s computer use is native desktop control: Claude directly interacts with your actual screen.
  • Different from Claude in Chrome, which uses DOM-based browser automation and only works inside Chrome.

Related to Anthropic’s acquisition of Vercept (February 2025), a computer vision company focused on desktop interaction.

Launched 17 March 2026. Available on Pro and Max.

Send tasks from your phone to your desktop Cowork session. Requires the Claude mobile app (iOS or Android) at the latest version and Claude Desktop open on your Mac or PC.

How it works:

  1. Open Claude Desktop on your computer
  2. Open the Dispatch pairing screen (in Cowork settings)
  3. Open the Claude mobile app on your phone and scan the QR code
  4. Send tasks from your phone: they appear in your desktop Cowork session

Useful for operators who think of tasks while away from their desk. Send “Prepare the weekly sales report from the data in my Reports folder” from your phone, and it’s waiting for you when you return.

Launched 20 March 2026. Desktop only, paid plans.

Projects are persistent workspaces in Cowork. Instead of starting each session fresh, a project remembers its context:

  • Linked folders: associate local directories with a project so Claude always knows where to find the files
  • Custom instructions: set project-specific instructions that apply every time you work in that project
  • Recurring tasks: define tasks that run on a schedule within the project context
  • Per-project memory: enable memory that’s scoped to the project, keeping context separate from your other work

Projects are especially useful for ongoing work: a client engagement, a monthly reporting process, or a product launch. Rather than re-explaining the context each session, Claude picks up where you left off.
