Claude Finally Enters the Personal Assistant Game with Duet

TL;DR: Claude Duet is a new Anthropic agent app that checks your connected apps, sends a morning brief, and messages you when something needs you. It’s a waitlisted research preview for US Pro and Max subscribers, included in those plans. It asks before it sends, pays, signs or deletes.

I’m on the Claude Duet waitlist with my personal account and a Team account. I haven’t tried it, so this is my read of Anthropic’s announcement and help page.

Anthropic calls it “a new app where Claude works as a proactive agent.” It says it built Duet “for professionals and small business owners with more on their plates than they can track.” It runs as its own app on iOS and Android, and on claude.ai.

Who It’s For

Read the examples and it’s clear who Anthropic has in mind. The connector list is QuickBooks and Stripe for unpaid invoices, payroll in Gusto, agreements through Docusign, deals in HubSpot, a Shopify store. The early testers Anthropic quotes include a real estate broker and a restaurant owner with about 110 employees.

That’s a small business owner’s week, not a developer’s.

Proactive Is the Pitch, Not the Difference

My first read was that proactive is what sets Duet apart from Meta’s Muse and OpenAI’s Dots. The Verge frames Duet as a competitor to both. So I checked Meta’s and OpenAI’s own pages, and that read doesn’t hold up.

Meta says Muse “proactively helps with people’s goals and suggests ideas” and can “make suggestions unprompted.” OpenAI says your dot “proactively figures out the next steps” and brings you work “sometimes before you even think to ask.” OpenAI even has a name for its background work: “proactive research.”

All three say proactive. So I’m treating it as Anthropic’s marketing angle, not the difference.

What does look different, going only by the vendors’ own pages:

• Who it’s for: Anthropic built Duet “for professionals and small business owners.” Meta pitches Muse as a personal agent “built for everyone.” OpenAI is rolling Dots out on Pro, Business Premium and Enterprise plans.
• The morning brief: Duet sends a short brief each morning on the most important items across your connected apps. Neither the Muse nor the Dots page I read describes a daily brief.
• How often it looks: Duet checks your connected accounts “every few hours,” because checking nonstop would burn through your plan’s limits. OpenAI says dots “can work towards your goals 24/7.” Anthropic’s help page spells out the tradeoff: “something urgent can arrive between checks.”
• Seeing its work: Duet’s help page says you can’t watch it work in its browser or take over. OpenAI says you can open your dot’s computer “at any time to inspect its work.”

Asking before acting isn’t a difference. Muse checks before sending an email or making a purchase, and Dots have rules for when to act and when to ask.

On Paper, Side by Side

Each cell comes only from that company’s own pages. Where a page doesn’t say, I wrote “Not stated.”

Feature	Muse (Meta)	Dots (OpenAI)	Duet (Anthropic)
Who it's for	"Built for everyone"	Pro, Business Premium and Enterprise plans	Professionals and small business owners
How it reaches out	Comes back when something changes or it needs approval, in the Muse app or WhatsApp	Messages you with progress, questions or decisions, in ChatGPT, Slack or Teams	A morning brief, then a message when something needs you
How often it checks in	Not stated	Can work toward your goals 24/7	Every few hours
What it can see or act on	Apps you connect, from its own cloud computer with a browser	Apps you connect, its own cloud computer and browser, and your laptop if you allow it	Apps you connect in Claude, plus its own cloud browser; not the files on your computer
Price and availability	Free for most of what people need, with paid plans; US on iOS, Android and muse.ai	First dot included in Pro or Business Premium; eligible markets	Included in Pro and Max; US only, by waitlist

What It Won’t Do Without You

Before it sends a message, makes a payment, signs a document, or deletes anything, Duet shows you what it’s about to do and waits for approval. Some things are off-limits even with approval, like trading securities or moving money between accounts.

Purchases go through Stripe’s Link or Shopify’s Shop Pay. The help page says each purchase uses a one-time card that only works for that purchase.

On prompt injection, the help page is honest: “no defense is perfect, which is one reason consequential actions need your approval.” Anthropic also says a new classifier is designed to reject requests to share things like credit card numbers and government ID.

The Fine Print

• Who gets in: US accounts on Pro or Max (sorry, EU friends, I’ll save you a seat), invited from the waitlist in waves. Not Team or Enterprise yet, though Anthropic plans to add them later.
• What it costs: included with Pro and Max at no extra cost during the preview.
• Usage: it shares your plan’s limits, and the background checks and morning brief count too. You get one full limit reset when you’re admitted, available until November 30, 2026.
• Model: you can’t pick one. It runs on Claude Opus 5.5.
• What it can’t do yet: you can’t watch or take over its browser, Microsoft 365 isn’t available yet, and it doesn’t make phone calls or text other people.

Anthropic is upfront that this is early. It “still might misread a thread or miscalibrate what’s urgent,” and personal errands like booking tickets “aren’t quite as strong.”

What I’d Do

If you run a small business on Pro or Max in the US, join the waitlist with the email on your Claude account, since access is tied to that address. When you get in, I’d connect one or two apps first and read every approval request before you tap it.

As for me, I’m not a Muse user, and Dots didn’t bring enough to the table to get me to subscribe to ChatGPT. I’m also not really the target audience on my personal account, so I’m not sure how much value I’ll find right off the bat. I’m more hopeful about getting my Team account in. I always seem to have at least one or two emails waiting for me, and I suspect I’m not alone there.

I still haven’t figured out what I’d hand it first.
