Anthropic launched Claude Duet on 21 October 2026, and the idea is simple: instead of waiting for you to type something, Claude comes to you. It watches the apps you connect, tells you what needs your attention, does the jobs you hand it, keeps working while you are away, and checks with you before it acts on your behalf. It is a research preview for Pro and Max subscribers in the US only, via a waitlist, so UK owners cannot try it yet. We have not used it. Here is what we would tell a client about it today.
What Claude Duet actually does
According to Anthropic's own announcement and the coverage that followed, Duet is a separate app where Claude works as a proactive agent. It runs on Claude Opus 5.5, and its background activity counts towards your existing plan limits. Reports say it can pull together a short morning brief from your connected apps, run periodic checks that trigger alerts, and take on chores such as scheduling and invoicing.
The part we pay most attention to is the approval step. Coverage says Duet asks before it sends messages, makes payments, signs documents or deletes files. Anthropic also says it never directly sees your passwords, and that it can still misjudge what is urgent. That last admission is the honest bit. An assistant that decides what to show you first is only as good as its sense of priority, and that will take tuning.
Details such as the number of connectors come from posts and secondary reporting rather than Anthropic's announcement, so we are leaving those figures out. If you want the facts first-hand, read the MacRumors report on the launch and Anthropic's own post when it reaches the UK.
It is not alone: OpenAI got there first
This is the second big proactive assistant in a month. OpenAI launched Dots at its developer conference on 29 September. Each Dot is a persistent agent with its own cloud computer, reported to connect to more than 4,000 apps and reachable through ChatGPT, Slack and Microsoft Teams. In one early-tester example, an agent noticed an unbilled invoice, prepared it and waited for approval before sending it. Tom's Guide reports that most ChatGPT users cannot try Dots yet either, because rollout started with paid tiers in eligible markets.
So the direction of travel is clear. The big AI companies all think the next step is an assistant that starts the conversation. The honest position for a UK small business is that you can read about it this week and use it later.
Why a small business should care
The pitch only works if there is a pile of work worth chasing, and for most owners there is. The Amex SME Barometer from July 2026, which surveyed 1,000 UK business owners, found owners spend about 11 hours a week on admin or finance work, roughly six working days a month, and about half that time on sales and business development. You can read the figures in Retail Times.
That is the gap a proactive assistant is aimed at: the unanswered quote, the invoice that never went out, the calendar clash you spot at 9pm. Each one is small. Together they eat the week.
The uncomfortable part
An assistant that acts in the background is a different kind of risk from one that answers a question. If it misreads a priority, you lose a morning's focus. If it sends the wrong message to a customer, you lose some trust. That is why the approval step matters more than any feature on the list, and why we would be wary of any tool that offers to skip it. Anthropic says Duet can misjudge urgency, and we believe that. Treat the first weeks of any tool like this as a trial, not a rollout.
Three things to do this week, before it reaches the UK
1. List the jobs you would want chased. Write down the five small jobs that slip every week. Quotes sent with no follow-up, invoices raised late, enquiries that sit unanswered, meetings with no prep. This list is your test plan for any proactive tool, from any vendor.
2. Write your approve-first rules. Decide now what an assistant may do alone and what needs your yes. Our starting point would be that anything that sends a message to a customer, spends money, signs something or deletes something needs a person to approve it. Drafting, sorting and summarising can run without you.
3. Run a manual version today. You do not need Duet to see whether the idea helps. Once a week, paste your recent emails and your calendar for the coming days into Claude or ChatGPT and use this prompt:
Here are my emails from this week and my calendar for next week. Tell me the five things that most need my attention, in order, and say why for each. For any that need a reply, draft it for me to check. Do not assume anything I have not told you. If you are unsure what is urgent, ask me.
Remove anything private first, such as customer details you do not need to share. It takes ten minutes, and it shows you quickly whether a "what needs me first" briefing would change your week. If it does, you will be ready when the real thing arrives. If it does not, you have saved yourself a subscription.
What we would tell a client
Do not wait for Duet, and do not rush to buy a rival because of the headlines. The useful move is the same either way: know which jobs you want taken off your plate, and know where a human has to say yes. Tools that watch your inbox will keep arriving. Owners who already have those two answers will get value from them in the first week, and the rest will spend a month working out what to ask.
We build these kinds of set-ups for UK businesses, so if you would like to work out which of your five jobs is worth automating first, book a free consultation below.
