Claude Duet: Claude's New Personal Assistant You Text Like a Person (2026 Guide)

Claude Duet is a version of Claude you message the way you'd message a person — by typing or by talking — and it actually goes and gets things done in your apps. It runs on its own computer in the cloud, so it keeps working after you close the app. It tells you when something needs you. And it's designed to ask before it sends a message, makes a payment, signs a document or deletes anything. It's a research preview from Anthropic, and I'll be honest: this is the one I've been waiting for.

What is Claude Duet, in plain English?

Here's the difference. With a regular chatbot, you do the running around: open the chat, ask, copy the answer, paste it into your email, go back. With Duet you send one message — "find the unpaid invoices and draft reminders" — and it goes into the right apps, does the work, and comes back with drafts waiting for your OK. Less "tool you use," more "assistant you have."

• ✓It already knows you. Duet uses your Claude account, so the memory, skills and connectors you've already set up in Claude are there from your very first message. No starting from zero.
• ✓It works while you don't. It has its own cloud computer, so a job keeps going after you put your phone down.
• ✓It speaks up first. It flags what needs your input, sends updates during the day, and follows up on threads that went quiet.
• ✓It asks before the big stuff. Sending, paying, signing and deleting all wait for your approval.

What can Claude Duet actually do?

A morning brief, every single morning

Every morning Duet goes through your email and calendar, flags what matters most, and may already start the first steps — like drafting replies for you to review. Imagine opening your phone to "here are the three things that need you today, and I've drafted the answers." That's the idea.

One main thread, plus channels for each topic

There's one main thread that picks up right where you left off. You can also open separate channels for different topics — one per client, one for the house, one for a launch — and they all share the same memory. Organized, without having to explain yourself twice.

Big jobs, delivered as real files

For larger work you describe the goal, and Duet picks the apps it needs and estimates the effort. The results come back as files you can edit — research briefs, financial models, slide decks, dashboards — and they show up in the Make tab.

A Tasks tab that keeps score

The Tasks tab shows everything in progress and everything waiting on you. Duet posts in the main thread when a task finishes or needs a decision. My favorite detail: it can suggest a task is done, but only you can mark it completed. You stay the boss.

Your apps — plus a browser of its own

Duet works through the apps you've connected in Claude, such as Gmail, Google Calendar, Google Drive, Slack, QuickBooks, HubSpot, Docusign and Calendly, plus the Stripe connector for invoices. For websites that don't have a connector, it uses its own cloud browser. It also supports plugins — like the small business plugin — and can suggest ones that fit your work.

It can even shop for you (with your OK)

Inside Duet you can connect Link (Stripe's digital wallet) and Shop Pay (Shopify's wallet) to pay for purchases you approve. It asks before each purchase and uses a one-time card limited to that one purchase. Printer ink, reordered, without you opening a single website.

Things you can say to it

These three come straight from Anthropic's own examples — a great way to start:

How do I get Claude Duet?

Right now it's a waitlist. Invitations go out in waves, so there's no guaranteed date — which is exactly why you want to be on it today.

Is Claude Duet safe to hand my email and money to?

This is the right question, and I like Anthropic's answers here:

• ✓You approve every big action. Duet shows what it plans to do and waits before sending messages, making payments, signing documents or deleting anything. If you can't answer right away, it keeps working on other things and brings the request back later.
• ✓It shows its sources. When it reports a number, it tells you which email, file or spreadsheet it came from.
• ✓Some things are off-limits even if you say yes: trading securities, moving money between accounts, and accessing someone else's account.
• ✓Your passwords stay out of the chat. When a site asks for a password, you type it into a separate form on your device that sends it straight to the browser.
• ✓You hold the keys. You start each connection yourself and can disconnect any app at any time in Claude's settings. (Disconnecting stops future access; what it already remembers is kept.)
• ✓It's careful with what it reads. Emails and web pages can contain sneaky instructions ("prompt injection"). Duet is designed to treat that content as information, not orders — but Anthropic is clear that no defense is perfect, which is why your approvals matter.

What Claude Duet can't do yet

It's a preview, so here's the honest list:

• ✓You can't pick the model. It runs on Claude Opus 5.5 and sets its own effort level.
• ✓You can't watch or take over its browser.
• ✓It checks your accounts at set intervals, so something urgent may reach you a little late.
• ✓It can't see all the projects or files on your computer, and it can read — but not edit — your work in Claude.
• ✓No phone calls or texts. It can send emails from connected accounts, with your approval.
• ✓Some connectors have limits (Slack is one), and Microsoft 365 isn't available yet.
• ✓It can make mistakes. Read the drafts and approval requests before you confirm.

How much does Claude Duet cost?

During the preview it's included with Pro and Max at no extra charge. It draws from your five-hour and weekly limits at the same rate as a regular chat — and background work like the morning brief and check-ins counts too, so you may reach your limits sooner than usual.

What's coming next for Claude Duet?

Anthropic says Team and Enterprise plans are planned for later. Everything else in this section is my personal wish list, not a promise: availability outside the US (my Hebrew-speaking readers are waiting!), Microsoft 365, and a way to watch its browser while it works. I'll update this guide the moment any of it changes.
