Anthropic’s consumer AI agent Claude Duet is a capable but occasionally overeager assistant, according to a weeklong hands-on test by The Verge’s Allison Johnson. Duet is the company’s latest effort to sell agent software to people who don’t write code, following the earlier Claude Code coding agent and the more work-focused Claude Cowork. Johnson tested it against a busy travel and work schedule and found it by turns useful, nagging and eager to write about itself.
Duet, which has its own app supporting the iPhone Duo, carries Claude’s minimalist design. Users connect productivity and chat services, after which the agent surfaces suggestions as cards that can be swiped left or right to hide or accept. Johnson gave it her work email, calendar, Google Docs and Slack, and Duet connected details between a staff meeting summarized in an email from Gemini and a Slack direct message, and identified her boss through a shared Google Doc used for weekly one-on-one meetings.
Each morning Duet greeted her with a brief message and highlights for the day, including a reminder to pack an item needed for a video shoot before a flight, followed by suggested to-dos. It sometimes misread context. After Johnson told an interview subject a story would likely run Tuesday and that she would send a link, Duet worried the following morning that the unpublished draft would keep her from fulfilling that promise, missing the soft nature of the deadline and the early local hour for her editor.
In other cases it proved surprisingly helpful. When Johnson overlooked that upcoming time off would leave few working days before another large draft was due, Duet proposed a fix, offered to update the weekly notes doc for her editor and drafted a Slack message. The draft mimicked her lowercase writing style and a common abbreviation for the CMS, though it shortened “signature” to “sig,” which she said she never would. The message carried a “sent with Claude” label.
Duet frequently offered to start her drafts, which Johnson declined, and she described the prospect of the agent reviewing itself as uncanny. She said having the agent read every email, draft and Slack message felt strange even after opting in to data sharing, and she wondered whether relying on it for calendar entries and to-dos would leave her feeling disconnected from her workplace.
Johnson concluded that Duet is best used as a backstop for her own organizational systems rather than a replacement, and that it has no place in her creative process. She said Anthropic’s blog post notes the company is still testing Duet’s judgment about when to message users, and she questioned whether AI can grasp nuance and tone.
