The news of October 22ndAnthropic Yesterday (21 October) announced a new application in the form of a research preview Claude Duet,POSITION TO ACTIVE AI Agent(agent) Add the "All-weather Active AI Assistant" World War by Muse of Meta and Dots of OpenAI。

In terms of skills, the application collates critical cross-application matters on a daily basis, proactively alerts the issues that need to be addressed and continues to perform mandated tasks in the back office after users leave。
Claude Duet, based on Claude Opus 5.5, provides iOS, Android independent applications and claude.ai. The first list of candidates for U.S. Pro and Max subscriptions is open; the preview phase shares a set of limits with Claude's other functions。
Unlike normal chat robots, Claude Duet has an independent virtual machine and browser that can run on a continuous basis when the user device is shut down. Users can use text or voice for tasking, such as arranging meetings, organizing unread mail, tracking invoices, making financial or sales forecasts, developing dashboards, developing web applications, etc.; upon completion of the task, it will notify the user or request review。
In terms of tool ecology, Claude Duet can call more than 6,000 connectors and plugins in Claude Marketplace, covering common office and commercial services such as Gmail, Slack, QuickBooks, Stripe, Gusto, LinkedIn, HubSpot, Canva, Shopify, DocuSign. It can also complete user-confirmed online payments through Link or Shop Pay and use virtual cards to avoid the disclosure of real card numbers。

In terms of security design, Anthropic indicates that Claude Duet does not have direct access to the user password or login tokens; user approval is required before sending a message, paying, signing a document or deleting the content. The system is also equipped with a special sorter to intercept requests for the disclosure of sensitive information, such as credit card numbers, government identification documents, etc。
However, Anthropic admits that this is still an early version: Claude Duet may misread the conversation, the degree of urgency of the miscalculation; personal affairs are relatively weak and it is not possible to show the user its browser operation。
