Claude Duet for Windows

Claude Duet for Windows Summary

Claude Duet for Windows is a proactive AI assistant from Anthropic that can be accessed through a web browser on Windows computers. Powered by Claude Opus 5.5, Claude Duet helps professionals and business owners manage information, automate workflows, and delegate complex tasks to an autonomous AI agent. The assistant can monitor connected applications, prepare daily briefings, draft communications, analyze business information, and complete projects using its own cloud-based virtual computer. Users interact with Claude Duet through a persistent conversation interface and can review work or approve consequential actions before they are completed. Claude Duet is currently available through Claude rather than a dedicated Windows application, with research-preview access limited to eligible US Pro and Max subscribers.

AI assistant highlights

• Receive proactive briefings about important emails, calendar events, business activities, and outstanding decisions.
• Delegate research, reporting, document creation, dashboard development, and financial forecasting tasks.
• Connect to thousands of supported applications through Claude connectors and plugins.
• Automate workflows involving CRM platforms, accounting systems, calendars, email, and other business software.
• Allow tasks to continue running on a cloud computer independently of the Windows PC.
• Review and approve sensitive actions before the assistant sends communications, makes purchases, or changes important information.

Built for autonomous business productivity

Claude Duet is designed to operate as a proactive digital assistant rather than a traditional question-and-answer chatbot. Users can delegate responsibilities through natural-language messages and allow the assistant to determine which tools and actions are required. It can organize information from multiple services, prepare supporting materials, and identify tasks that need attention. Claude Duet also provides proactive updates instead of requiring users to manually check each connected application.

Cloud computer and browser automation

Claude Duet operates through a cloud-hosted virtual machine equipped with its own browser. This allows the assistant to navigate supported websites, interact with connected applications, and complete workflows without relying on the user's Windows computer for execution. Tasks can continue after the browser is closed or the PC is shut down. During the research preview, users can review progress and results, but cannot directly watch or take control of the assistant's cloud browser.

Business applications and integrations

Claude Duet supports more than 6,000 connectors and plugins across the Claude ecosystem. Supported integrations include Gmail, Google Calendar, Google Drive, Slack, HubSpot, QuickBooks, Stripe, Shopify, and Docusign. These connections support activities such as reviewing customer communications, preparing invoice reminders, organizing business documents, and drafting agreements. Some services and operations have restrictions, and Microsoft 365 integration is not yet available for Claude Duet.

Research, analysis, and document creation

Claude Duet can perform complex tasks that require gathering information, reasoning across multiple sources, and producing structured deliverables. Examples include creating financial forecasts, preparing sales reports, building dashboards, researching competitors, and developing prototypes or web applications. The assistant can combine information from connected services and return completed documents, spreadsheets, presentations, or other outputs for review.

Persistent memory and proactive notifications

Claude Duet uses memory, skills, and connected applications from the user's existing Claude account. It maintains conversational context and can search eligible past conversations to support ongoing projects. The assistant periodically checks connected accounts and provides notifications when important information requires attention. Users can influence what the assistant monitors and how often it communicates.

Security and approval controls

Claude Duet incorporates safeguards for actions that may have financial, legal, or operational consequences. It is designed to request user approval before sending messages, making purchases, signing documents, or deleting information. Authentication credentials are handled separately from the AI model, and additional protections help reduce risks from malicious instructions encountered in external content. Certain financial activities remain prohibited even with user approval.

Windows compatibility and availability

Claude Duet can be accessed from a supported web browser on Windows through claude.ai. Anthropic has not released a dedicated Windows application for Claude Duet. Access currently requires a US Claude Pro or Max subscription and an invitation to the research preview. Claude Duet is included with eligible subscriptions, and its activity shares the same usage limits as the rest of Claude. Team and Enterprise subscriptions are not yet supported.
