Claude Duet: an AI assistant that asks before it acts

Picture a Thursday morning. You run a small bookkeeping office, and before you've finished your first coffee your phone buzzes. It's your AI assistant. Two clients still haven't sent their receipts, a supplier wants paying by Friday, and it's drafted a polite reminder to each client. The emails are sitting there, waiting for you to say yes.
That's a made-up Thursday, but it isn't far off. On 21 October Anthropic, the company behind Claude, opened a research preview of Claude Duet. It's a new app where Claude keeps an eye on your connected apps, like email and your calendar, tells you what needs your attention and keeps working after you put your phone down. Anthropic says it built Duet for "professionals and small business owners".
My short answer is this. It isn't available here yet, so there's no rush. If it reaches Australia, I'd check the privacy setting first and try it on your own calendar and admin. If your office holds client files, tax records or patient notes, keep those out of it. It checks your connected accounts every few hours on its own, and I wouldn't leave anything running unattended over client details.
What happens to your clients' information?
Start here, because Duet reads a lot. Anthropic says it can read your inbox, draft replies, book things and run routines while you're away.
Duet runs on your Claude account and uses its settings. On Pro and Max plans, Anthropic uses your chats to improve its models if you've allowed it. Chats flagged for a safety review may also be used for its safety work. The switch is called Help Improve our AI models. Select your name, then Settings, then Privacy, and you'll find it there. Check it's off before you connect anything. Privacy settings like this are part of every Claude set-up.
Anthropic has built in some protections too. Duet never sees your passwords or sign-in tokens. A separate check looks at each message before it goes out. It's designed to refuse to share full card numbers, bank account numbers or government ID numbers, even if you ask it to. Health or money details only go out if you've clearly said so. Anthropic is upfront that these checks will sometimes miss something.
If you disconnect an app, Duet stops reading it from then on, but what it's already learned stays in its memory until you reset it.
The Office of the Australian Information Commissioner recommends that businesses don't put personal information, and particularly sensitive information, into publicly available AI tools.
What does it need your yes for?
Before Duet sends a message, makes a payment, signs a document or deletes anything, it shows you exactly what it's about to do and waits for your approval. Anthropic says the approval shows the action, where it's going and what's in it, including every recipient.
Some things are off-limits even if you approve them, like trading securities or moving money between accounts. Some steps can never be set to "don't ask me again", however often you've said yes. Paying or sending money is one of them.
Anthropic itself warns that too many approval requests teach people to tap through them, sometimes without thinking it over.
Can you get it in Australia yet?
Not yet. During the research preview it's only available in the US, through a waitlist, on the Pro, Max and Ultra plans. It isn't on Team or Enterprise plans, though Anthropic says it plans to bring it to them later. Its Microsoft 365 connection isn't available yet either.
Its background checks also count toward your plan's usage limits, so you may hit them sooner.
People are talking about it. On 8 November the Hacker News thread on the launch had 539 comments. That's people's opinions, though, and it won't tell you how Duet would suit your business.
What should you check before it reads your inbox?
Which apps can it reach? Duet uses the apps you've already connected to Claude. Switch off anything it doesn't need.
Will you read every approval? Read each one right through before you tap, even on a busy day.
Where do your client details live? If an inbox or calendar holds client names or files, leave it unconnected. Start with one that doesn't.
Do your staff know the rules? An AI use policy puts what can go into AI, and who checks what comes out, in writing.
Do you know where the reset is? Find the memory reset in its settings, so you can clear what it's picked up if you ever need to.
Would you give a new PA your inbox on day one?
Think about the first week of a new personal assistant. You'd show them how you like things done, let them draft a few emails you send yourself, and hand over more once they've earned it. An AI assistant that works while you're away deserves the same slow start.
