Anthropic launches Claude Duet: a proactive AI agent built for small business owners

US AI company Anthropic has announced a new tool called Claude Duet — an AI assistant that works on its own without waiting for you to ask a question.

Unlike ordinary chatbots, Duet comes to you. Every morning it sends you a short brief of the most important items across your connected apps — email, calendar, and business systems. During the day it keeps checking those apps every few hours, and messages you only when something needs your decision. No need to open 100 tabs to see what's going on.

Duet is built on the company's Claude Opus 5.5 model. It runs on its own cloud virtual machine with its own browser, so it keeps working even when your phone or computer is off.

Anthropic says it designed Duet specifically for professionals and small business owners with too much to track. An early example is Amin Ebrahimi, owner of the Shahs of Kabob restaurant in the US with about 110 employees, who has used it for accounting, customer support and marketing. "I don't need to open up 100 tabs," he said, according to Anthropic.

The tool connects to more than 6,000 connectors in the Claude Marketplace, including Gmail and Slack. For a business owner, it can check systems like QuickBooks or Stripe for unpaid invoices and draft reminders, prepare payroll, draft follow-up emails from HubSpot records, send contracts for signature through Docusign, and even set up a Shopify online store.

Safety comes first: Duet must ask your permission before sending a message, making a payment, signing a document or deleting anything. "It shows you exactly what it's about to do and waits for your approval," the company says. Buying securities or moving money between accounts is completely off-limits — even with your approval. It also cannot see your passwords, and a dedicated system rejects requests to share credit card numbers or government IDs.

Payments go through Stripe Link: Duet confirms the item, Link asks you to approve the spend, and payment comes from a virtual card so your real card number is never shared. "Building Claude Duet's purchases on Link keeps people in charge of every dollar," said Rahul Patil, Anthropic's chief technology officer.

There are important limitations: Anthropic admits this early version "still might misread a thread or miscalibrate what's urgent," and it is less effective at personal errands like booking tickets. Its background checks also count against your plan's usage limits.

For now Duet is available only in the US, to people on the waitlist with Pro and Max plans — at no extra cost. It works through iOS and Android apps and the claude.ai website.

Competition is heating up: Meta already has its agent called Muse, downloaded by millions of people, and last month OpenAI launched its always-on "Dots" agents. The AI agent wars have officially begun.

What does this mean for you?

Small business owners: This is your story. An agent that reminds you about an unpaid invoice, drafts customer emails and tracks sales while you sleep is like an extra employee who never sleeps. Note: it hasn't reached Africa yet — but be ready, because when global competitors arrive, they arrive fast.

Farmers: A produce seller could one day have an agent tracking market prices and buyer orders every morning. This technology shows the new direction: AI is becoming less a tool you talk to and more an assistant that works for you.

Students: If you're studying business or technology, AI agents are the new job skill. Learn how to direct them, supervise them and verify their work — that is tomorrow's job.

Parents: If you hear a child or employee say "the AI did it for me," remember Anthropic's rule: a good agent must ask before acting. Teach children never to let any AI send money or share personal information without them seeing and approving it first.
