Overview
Cowork is a research preview mode in the Claude Desktop app for macOS that extends Claude's capabilities beyond coding to assist with complex, multi-step knowledge work tasks. Unlike traditional AI assistants that require manual file uploads and step-by-step guidance, Cowork can autonomously read, modify, and create local files based on natural language instructions. Currently available for Claude Max subscribers on macOS, it operates within a virtual machine environment on your computer, enabling tasks like organizing downloads, processing receipts into expense reports, synthesizing research from multiple sources, and generating professional documents with working formulas. Other plans can join a waitlist for future access.
Built on the same agentic architecture as Claude Code, Cowork reduces the need for constant supervision by planning and executing tasks independently. It breaks complex workflows into subtasks and coordinates parallel workstreams to complete them efficiently. The tool integrates with Claude's existing desktop extensions and the Claude in Chrome extension, allowing it to perform web-based research alongside local file operations. As a research preview, Cowork represents Anthropic's exploration into autonomous AI agents for everyday work tasks, with ongoing development informed by user feedback.

Key Features
Direct Local File Access — Cowork can read from and write to specific folders on your computer without manual uploads, enabling seamless file organization, batch processing, and document creation directly on your local system.
Autonomous Task Execution — Plans and executes complex, multi-step workflows independently based on natural language instructions, coordinating parallel workstreams and subtasks without requiring step-by-step guidance.
Professional Document Generation — Creates polished deliverables including Excel spreadsheets with working formulas and conditional formatting, PowerPoint presentations, and formatted reports from unstructured inputs like voice memos or meeting notes.
Long-Running Task Support — Handles extended workflows without conversation timeouts or context limits, allowing Claude to work on complex projects that require sustained focus and multiple sequential operations. Requires an active internet connection and the Claude Desktop app to stay open throughout the session.
Secure VM Environment — Runs tasks in a virtual machine on your computer for isolation, with defined boundaries for file and network access. While it requires explicit permission before significant actions, Claude can still make real changes to files you grant access to, so review plans carefully and consider using a dedicated working folder.
Connectors and Desktop Extensions — Can use your existing connectors and desktop extensions (MCPs), and pairs with Claude in Chrome for browser-based steps. Examples of available connectors include services like Asana, Notion, and PayPal, with availability depending on the connector directory and your region.

Important Notes:
- Requires Claude Desktop app for macOS
- Pricing shown is for web subscriptions; pricing on mobile platforms may vary
- Cowork requires a paid Max plan; Anthropic does not advertise a Cowork-specific free trial in its official documentation (promotions may vary)
- Cowork consumes more of your Max usage allocation than standard chat; reserve it for complex tasks that benefit from file access
Best For
- Knowledge workers who frequently perform repetitive file organization, data extraction, or document generation tasks on macOS
- Researchers synthesizing information from multiple sources into structured reports or analyses
- Professionals managing large volumes of receipts, documents, or files requiring systematic processing
- Max plan subscribers seeking autonomous execution of complex workflows without step-by-step guidance
- Users comfortable granting AI access to specific local folders with appropriate safety precautions
FAQ
Is there a free trial available?
Cowork requires a Claude Max subscription ($100-200 per month). Anthropic does not currently advertise a Cowork-specific free trial in its official documentation, though limited-time promotions may occasionally be available. It is not accessible on the Pro plan or lower-tier subscriptions.
What platforms does Cowork support?
Cowork is currently available only on macOS through the Claude Desktop app. It does not support Windows, web browsers, iOS, Android, or other platforms. Sessions do not sync across devices, and you must keep the desktop app open to maintain an active session.
Can Cowork access all files on my computer?
No. Cowork only accesses folders you explicitly grant permission to. It operates within a virtual machine with defined boundaries, and requires explicit permission before performing significant actions. You maintain full control over which directories Claude can read or modify.
What happens if Cowork makes a mistake?
As the user, you are responsible for all actions performed by Cowork on your behalf, including file modifications, data deletion, messages sent, or financial transactions. Always monitor tasks closely and grant access only to folders containing non-sensitive information.
Can I use Cowork for web-based tasks?
Yes, when paired with the Claude in Chrome extension, Cowork can perform web-based research, gather market data, and automate online tasks alongside local file operations. However, you should limit access to trusted websites to reduce security risks. Anthropic strongly advises against using Claude in Chrome for actions involving sensitive information such as passwords, financial data, or personal credentials.
Does Cowork work with other Claude features like Projects?
No. Cowork runs in a separate "Tasks" mode in Claude Desktop, distinct from standard chat sessions. It does not currently integrate with Projects or Memory features, nor does it support chat or artifact sharing from standard Claude conversations.
What are the main security risks?
Claude may take destructive actions such as deleting local files if given ambiguous instructions. Web content is also a primary vector for prompt injection attacks. To minimize risks, provide clear instructions with explicit constraints, avoid granting access to folders containing sensitive data, limit Claude in Chrome to trusted sites only, and monitor for unexpected behavior such as accessing unmentioned files or websites.
Can I cancel my Max subscription anytime?
You can cancel Pro or Max subscriptions at any time from Settings > Billing. Cancellation takes effect at the end of your current billing period. To avoid charges for the next billing cycle, cancel at least 24 hours before the next billing date.
