Claude Duet puts an always-on agent in front of small-business owners — on a plan meter

Anthropic's research preview, announced Oct. 21, briefs founders each morning, works in the background across 6,000+ connectors, and asks before it sends, pays, or signs — but background checks count against existing Pro and Max limits.

Anthropic on Oct. 21 unveiled Claude Duet, a research-preview agent that watches a user’s connected apps in the background, sends a short brief each morning, and pings the owner when something looks urgent. It arrives on the same week OpenAI’s Dots and Meta’s Muse are jockeying for the same slot in the small-business inbox, and it carries the clearest tell of where this market is headed: Duet runs on top of Opus 5.5 and burns against existing Pro and Max plan limits.

That meter is the story. Pro and Max subscribers in the US get Duet at no additional charge during the preview, access gated by waitlist, available on web, iOS, and (per the preview listing) Android. But every background sweep counts. Anthropic says the agent checks connected accounts every few hours precisely because nonstop polling would chew through plan capacity faster. The agent’s attentiveness is a line item.

What it does, functionally, is close the gap between noticing a lead and acting on it. Duet taps the Claude Marketplace’s 6,000+ connectors and ships with 13 named integrations at launch, including Gmail, Slack, HubSpot, LinkedIn, Shopify, DocuSign, Canva, 1Password, Stripe Link, Shopify Shop Pay, Intuit QuickBooks, and Gusto. It can scan QuickBooks or Stripe for unpaid invoices and draft the reminder, prepare and run payroll in Gusto, and set up or manage a Shopify store. For a founder-led business without a sales hire, that’s a background colleague doing the work nobody got around to. Related context on buyer appetite shows up in HubSpot’s own survey of rising AI budgets, and the funnel-automation shift is already visible on the consumer side in TikTok’s full-funnel pivot.

The guardrails are deliberately conservative. The agent asks for approval before sending a message, making a payment, signing a document, or deleting a file. Trading securities and moving money between accounts are off-limits even with approval. Anthropic deployed a new classifier to screen each message against data leakage, and by default Duet declines prompts asking for credit card numbers or government identification. The company concedes the agent “might misread a thread or miscalibrate what’s urgent.”

Autonomy sold by the drip, metered against the subscription. That’s the shape of the agent economy now.
