Claude Cowork Setup Guide (2026): Desktop, Web & Mobile

// August 20, 2026

Claude Cowork is the non-terminal way to hand Claude a complex outcome and let it plan, use tools, work across files and apps, and return a finished deliverable. It is now available on paid Claude plans across desktop, with cloud sessions available on web and mobile as Anthropic rolls out the beta.

This guide has been updated for the current cloud-session model, Pro/Max/Team/Enterprise access, Windows and Linux support, mobile access, scheduling, plugins, and the newer permission modes.

| Quick answer | Current setup | | --- | --- | | Who can use Cowork? | Paid Claude plans: Pro, Max, Team, and Enterprise | | Where does it work? | Claude Desktop, claude.ai, and the Claude mobile app; availability varies during beta rollout | | Do I need Desktop? | Only when a task needs local files, your browser, or computer use | | Can tasks keep running? | Cloud and scheduled tasks can continue while your computer is asleep |

What Is Claude Cowork?

Cowork brings the agentic capabilities behind Claude Code to knowledge work. Instead of managing every prompt-response turn, you describe an outcome and Claude:

  • Makes a plan
  • Executes multi-step tasks
  • Creates, edits, or organizes files
  • Reports progress as it works

Key difference from regular Claude:

  • Regular chat: You prompt, Claude responds, you prompt again
  • Cowork: You queue tasks, Claude works through them in parallel

You can steer the work while it runs or step away and return to the output. Cloud sessions run in an isolated environment on Anthropic's servers; when a task needs something on your computer, Claude reaches it through the connected Claude Desktop app.

What Cowork Can Do

File and Document Management

  • Reorganize downloads by sorting and renaming files
  • Create spreadsheets from receipts or screenshots
  • Consolidate scattered notes into structured documents

Research and Analysis

  • Synthesize research from multiple sources
  • Summarize documents and extract key insights
  • Compile findings into reports

Document Creation

  • Draft reports, proposals, or presentations from scattered notes
  • Create structured documents from rough outlines
  • Generate first drafts that you refine

Data and Analysis

  • Parse and organize data from various formats
  • Create summaries from spreadsheets
  • Build structured datasets from unstructured sources

Prerequisites

Before you begin, make sure you have:

  • A paid Claude plan — Pro, Max, Team, or Enterprise. Enterprise availability may depend on administrator settings.
  • An active internet connection — Required while a Cowork task is running.
  • Claude Desktop when using local resources — Install the latest app for macOS, Windows, or Linux beta when Cowork needs local files or your browser.
  • A low-risk test task — Start with copied files or a dedicated folder until you understand the permission model.

Step-by-Step Setup

Step 1: Choose Where to Start

You can start Cowork from:

  • Claude Desktop for work involving local files, Chrome, or desktop apps
  • claude.ai for a cloud session with connected services and uploaded files
  • Claude mobile for starting or monitoring work away from your computer

If you need local access, install or update Claude Desktop before continuing.

Step 2: Start a Cowork Session

  1. Open Claude on desktop, web, or mobile.
  2. Select Cowork in the message-box mode selector.
  3. Describe the finished outcome you want, the source material Claude may use, and the format you expect back.
  4. Review Claude's proposed approach before it begins acting.

Step 3: Connect Files Carefully

For a task that needs files on your computer:

  1. Open the session in Claude Desktop.
  2. Choose the smallest folder that contains the required material.
  3. For your first task, create a dedicated workspace: 
    mkdir ~/cowork-tasks
  4. Copy non-sensitive test files into that folder and connect it to the session.

Security note: A connected folder defines what Claude can read and change. Do not connect a broad home directory when one project folder will do.

Step 4: Configure Connectors (Optional)

You can enhance Cowork's capabilities by connecting external data:

  1. Open the + menu in the Cowork composer or go to Customize → Connectors.
  2. Enable only the services required for this task, such as:
    • Gmail
    • Google Drive
    • Notion
    • Slack

Read access lets Claude gather context; write-capable tools can change external systems. Review the selected permission mode before granting write access.

Step 5: Add Instructions or Plugins (Optional)

Use global instructions for preferences that should apply to every session, and folder instructions for project-specific context. Cowork plugins can bundle skills, connectors, and sub-agents for a repeated role or workflow.

Keep the first run simple. Add customization after the basic workflow succeeds so it is easy to identify which instruction or integration changed the result.

Your First Cowork Task

Start with something simple to build confidence.

Example 1: Organize Downloads

"Sort my downloads folder into subfolders: Images, Documents, PDFs, and Others. Rename files to remove timestamps."

Claude will:

  1. Scan the folder
  2. Categorize each file
  3. Create folders as needed
  4. Move and rename files
  5. Report what was done

Example 2: Create a Spreadsheet from Receipts

"Look through these screenshots of receipts and create an expenses spreadsheet with columns for Date, Merchant, Amount, and Category."

Claude will:

  1. Read each image
  2. Extract relevant data
  3. Create a properly formatted spreadsheet

Example 3: Draft a Report from Notes

"Read all the files in my project-notes folder and create a summary report that organizes the key findings by topic."

Claude will:

  1. Read each file
  2. Synthesize the information
  3. Structure it into a coherent report

How to Use Claude Code Without the Terminal

Clear explanation of what Cowork is and how to access it.

Staying in Control

Cowork is designed to keep you informed while it works.

What You Control

  • Files and connectors — Limit each task to the smallest useful set of folders, apps, and accounts.
  • Permission mode — Manual asks before actions; Auto approves read-only tools and applies safety checks to writes; Skip removes those checks and should be reserved for trusted, contained work.
  • Mid-task steering — Correct the plan, add context, or stop the task while Claude is working.
  • Permanent deletion — Cowork requires explicit approval before permanently deleting files.

Safety Considerations

Since Cowork can make real changes to files:

  • Start with a test folder — Practice with copies of non-critical files first.
  • Treat external content as untrusted — Websites, messages, and documents can contain prompt-injection attempts.
  • Use Manual mode for high-impact work — Especially when money, customer data, publishing, or account permissions are involved.
  • Review outputs — Check Claude's work before sharing, publishing, or replacing source files.

These aren't new risks, but agentic tools work differently than conversational AI. Take precautions while learning.

Usage and Limits

Cowork consumes more of your usage allocation than regular chat. Complex, multi-step tasks are compute-intensive.

If you hit limits frequently:

  • Use regular chat for simple queries
  • Reserve Cowork for multi-step work that benefits from file access
  • Break large tasks into smaller pieces

Advanced Configuration

Browser and Computer Use

When a connector does not cover a website or application, Cowork can use Chrome or interact with supported desktop apps through Claude Desktop. Keep the desktop app open and connected while a task is using local browser or computer access.

Use the most precise tool available: prefer a connector, then browser control, then screen interaction. The more direct the tool, the easier the task is to verify.

Global and Folder Instructions

Add global instructions in Settings → Cowork for preferences such as tone, formatting, and how you want decisions explained. Folder instructions are better for project context, naming conventions, and output requirements tied to one workspace.

Plugins

Cowork plugins package reusable skills, connectors, and sub-agents for a role or team. Add them after a manual version of the workflow is reliable; automation magnifies unclear instructions as quickly as it magnifies good ones.

Scheduled Tasks

Type /schedule in a Cowork task to create recurring work, or open Scheduled in the sidebar. Scheduled tasks run remotely, so they do not require your laptop to remain awake.

Dispatch from Mobile

Dispatch provides a persistent thread for assigning a task from your phone and having Claude work with the files, connectors, plugins, and apps available on your desktop. For desktop-dependent work, the computer must remain awake with Claude Desktop open.

Real-World Workflows I've Built

Daily Briefing Automation

Every morning, Cowork:

  1. Reads my notes from the previous day
  2. Checks my calendar for the day ahead
  3. Creates a daily briefing document with:
    • Yesterday's progress
    • Today's priorities
    • Key deadlines

Content Pipeline

For my newsletter and blog posts:

  1. Cowork reads research notes and drafts
  2. Creates structured outlines
  3. Generates first drafts
  4. Compiles everything into a content calendar

Project Documentation

When starting new projects:

  1. Cowork reads the project brief
  2. Creates folder structure
  3. Generates README with context
  4. Sets up standard templates

Troubleshooting

Claude Stopped Working

Cause: The task needed a local file, browser, or desktop app after Claude Desktop disconnected.

Fix: Reopen Claude Desktop and reconnect the relevant resource. Pure cloud and scheduled tasks can continue without the computer, but local-resource tasks cannot reach an offline device.

Files Aren't Appearing Where Expected

Cause: File permissions or wrong output location.

Fix: Check that you've granted appropriate folder access. Review the output location Claude specified.

Hitting Usage Limits Quickly

Cause: Cowork consumes more usage than standard chat.

Fix: Use standard chat for simple tasks. Reserve Cowork for complex, multi-step work.

Claude Keeps Asking for Permission

Cause: Manual mode is active, an organization policy requires approval, or the requested connector has write capabilities.

Fix: Keep Manual mode for high-impact tasks. For contained work, review the tool scope and switch to Auto only when you are comfortable with its safety checks.

What Changed Since the Research Preview

  • Cowork expanded from Max-only access to paid Pro, Max, Team, and Enterprise plans.
  • Desktop support now includes macOS, Windows, and Linux beta.
  • Cloud sessions can continue across web, desktop, and mobile without keeping a laptop awake.
  • Scheduled tasks, projects, plugins, browser actions, computer use, and mobile dispatch broaden the original file-management workflow.
  • The permission model now distinguishes Manual, Auto, and Skip modes.

Getting Started

  1. Use a paid Claude plan — Pro, Max, Team, or Enterprise.
  2. Choose your surface — Start on web or mobile for cloud work; install Claude Desktop for local files and apps.
  3. Create a safe test workspace — Use copied files in ~/cowork-tasks.
  4. Describe the outcome and constraints — Include the source material, desired format, and definition of done.
  5. Start in Manual mode — Watch the first run, then automate the parts you trust.

Cowork represents a shift in how we work with AI. Instead of constant back-and-forth, you describe outcomes and Claude executes. It's not magic—it's having a capable coworker who never gets tired.
