Usually it works like this: you ask, the AI answers. You are the boss, it waits for instructions.
Claude Duet flips that. The agent sits in the background, looks into your connected apps, and knocks when something gets important.
What Duet is
According to Engadget the company has introduced Duet as a personal "proactive" agent. An agent is an AI that does not just produce text but works through tasks on its own: finding appointments, sorting mail, building spreadsheets.
Reports name two main features:
- Daily briefing: Duet summarizes what matters across your connected apps.
- Targeted alerts: A message arrives only when something needs your attention.
You can also hand it tasks, such as scheduling a meeting, building a dashboard or drafting a forecast. According to reports it runs in its own cloud environment and checks your accounts every few hours. Not live, not in real time.
What it may not do alone
This is where it gets interesting for beginners. An agent that acts on its own can also mess up on its own. So there are guardrails. According to the reports, Duet needs your approval before sending messages, making payments, signing documents or deleting anything.
Trading securities and moving money between accounts are off the table entirely.
Anthropic also admits that the early version may misjudge urgency or miss something between two check rounds. In other words: trust it like an intern on day one. Keen, useful, sometimes off.
What is free, and what costs money?
Nothing is free here. Duet is currently a research preview (an early test) with a waitlist. According to reports, access first goes to Claude Pro and Max subscribers in the US. There are apps for Android and iPhone, plus the web.
For readers outside the US that means, as things stand: watch from the sidelines for now.
Is it for you?
Probably yes if you
- use many services (mail, calendar, chat) and drown in the stream,
- already pay for a Claude plan,
- are willing to approve every sensitive action yourself.
Probably not if you
- are just starting out with AI. A normal chat is plenty.
- dislike giving a program access to your mail and calendar.
On privacy, stay sober. Duet needs access to your apps, otherwise it has nothing to report. That is the price of any assistant like this, not just this one. To start carefully, connect only one app and see what happens. More in our comparison of the data hoarders.
What you can try right now
Even without the waitlist you can test the principle. Ask your chatbot every morning: "Here are my appointments and open items. Which of them is urgent today, and why?" You will quickly see whether such an overview helps you at all.
The link to apps runs through MCP for many agents, an open standard for AI connectors.
Unpaid assessment, my own opinion: the concept is exciting, the proof is still missing. An agent that rarely nags and reliably flags the important things would be a real win. An agent that keeps raising false alarms is just one more notification.
Try it if you get access. And at first, let it send nothing without you.
