Claude Duet, an assistant that works in the background, opens as a US research preview with a waitlist
Claude's product page says Duet sends morning briefs, handles tasks it receives by message and asks for approval before sending messages or making payments.
Claude has introduced Claude Duet, an assistant that keeps working while its user is away and asks for approval when a decision matters. The details come from a single source: the product page on Claude's website.
According to that page, Claude Duet is a research preview with a waitlist. It is open to Claude Pro and Max subscribers in the US and runs on Opus 5.5. Team and Enterprise plans are "not included yet," the page says.
Users give it work by text or voice message in one ongoing thread. It works on its own computer in the cloud, using apps the user has connected, and sends a message when a task is done or needs a decision. The page says it brings over the user's memory, skills and connectors from their Claude account.
The page describes a morning brief, flags for items in the user's inbox and calendar, and draft replies for the user to approve. It says Duet can also take on some of the work of running a business: finding unpaid invoices and drafting reminders, preparing payroll for review, getting contracts ready to send, and building briefs, decks or dashboards. Example screens on the page show it tracking a café opening checklist, preparing a fundraising deck and pointing to a jump in customer churn.
Why it matters: the page sets Duet apart from the regular Claude app. The app "waits for you to open a chat," while Duet "comes to you," it says. This means the assistant acts on its own between conversations, so the page lays out safeguards. It says Duet asks before sensitive actions such as sending messages or paying. Approvals, logins and safety checks run in the user's own cloud computer, and users can see what Duet has done and is doing, and steer it.
The page also names limits. Duet "may misread a thread or miscalibrate what's urgent," it says, and it can miss something that arrives between check-ins. During the preview, Duet draws on the same usage limits as the rest of the user's plan. Its background checks count toward those limits, and larger jobs such as building a financial model or a deck take more work.
Several things are not yet known from the source. The page gives no date for when the waitlist will open more widely, when Team and Enterprise plans will be added or whether Duet will reach users outside the US. It also does not say how much of a plan's usage a typical day with Duet would consume.
Duet is a standalone app for iOS and Android, and on a computer it can be opened on the web at claude.ai, according to the page.
