How to Use Claude Duet as a Business Owner

What is Claude Duet, in plain words?

Claude Duet is Anthropic’s always-on agent. It opened as a research preview on October 21, 2026. You message it like a person, by typing or by voice. It has its own cloud computer and browser, so it keeps working after you close the app. It checks your connected accounts every few hours and messages you when something needs you.

It carries over your memory, skills and connectors from Claude. Finished work comes back as files you can edit, such as a dashboard or a forecast.

What does Claude Duet cost, and how do you get it?

Duet has no extra charge during the preview, and you need a paid plan and an invitation to use it.

Pro	$20 a month, or $17 a month billed yearly	Waitlist, US accounts	November 6, 2026

What are the five best jobs to give Claude Duet first?

Start with unpaid invoices and work down to the Friday report, ranked by money first and hours second.

1. Aging receivables. Anthropic names this job, and it runs through a Stripe connector.

Check my connected Stripe and QuickBooks accounts for unpaid invoices. Group them by customer into 1-30, 31-60, 61-90 and 90+ days past due, largest first. Show the amount, oldest invoice and my last email to them. Draft one reminder per customer for my approval. Cite the source for every number. Do not send anything.

2. The morning brief. It comes built in, so you only have to shape it.

Change my morning brief. Lead with what changed overnight: late orders, large payments, big quotes and customer complaints. Skip newsletters and anything with no decision attached. For each item, show the source and what I need to decide. Tell me when you could not check a source.

3. Quiet customers. It already follows up on quiet threads. Point that at your customers.

Using my connected email and HubSpot, list every customer I have not heard from in 60 days who ordered in the 60 days before that. Rank them by what they usually spend. Show my last message to each one and draft a short check-in in my voice. Do not send anything or edit any record.

4. Quote follow-up. An open quote goes cold while everyone is busy.

Find every quote I sent by email in the last 30 days with no order and no reply in the last 7 days. Open a task to track them. Rank them by dollar value and draft a short follow-up for each. Do not send anything. Mark each one in the Tasks tab so I can close it myself.

5. The Friday report. Large jobs come back in the Make tab as a file you can edit.

Build my Friday report as a spreadsheet from my connected accounts: sales, cash collected, open invoices, open quotes and the three items that need me. Compare each number with last week. Cite the source for each number and mark anything you could not find. Share it with me only.

How do you set up Claude Duet in 20 minutes?

You set it up in six steps once your invitation arrives, and the wait for that invitation has no published date.

1. Join the waitlist on the product page with your Claude account email.
2. Open the invitation on your phone and follow the iPhone or Android steps.
3. Sign in with your Claude account.
4. Check which apps carry over from Claude. Disconnect any you do not want it reading.
5. Keep one money app and your email. Enter any password only in the form inside the app.
6. Paste prompt one and read the sources it cites.

What rules do you set before Duet touches the business?

Start read-only in practice: connect only what the job needs and let it read and draft until the work holds up. Anthropic publishes no read-only switch for Duet, so your connected apps and your words set the limit. Read comes first. Propose comes next. Act comes last.

• It may do alone: read and compare, then research and draft.
• It must ask first: send a message or pay. The same goes for signing or deleting. Anthropic builds this in.
• It may never do: move money or email a customer on its own. It also may never change a price or delete records.

Two of those need your help. Anthropic bars moving money between accounts even with your approval, and it keeps payments out of any “don’t ask again” rule. Email is different, so never choose “don’t ask again” on a customer email. Price changes depend on what your connected apps allow, so write the rule down.

Standing rules. Remember these. You may read, compare and draft. Ask me before you send, post or update anything. Never email a customer without my approval on that exact message. Never change a price or delete a record. If a number has no source, say so and stop.

Your rollout rule: one job and two apps for one full week of checked drafts. Read the recipients and amounts on every approval card. If you cannot approve right away, it finishes the rest and asks again later.

An agent sees only what it can reach. Point Duet at 40 scattered tabs and it gives the wrong answer faster. Data first, then AI. The Business Brain fixes the data first, and this guide shows how the wrong answers happen.

Where does Claude Duet break?

Claude Duet breaks on access first, since most owners cannot get it today and no team can.

1. It is one person’s tool. Team and Enterprise plans are out as of November 6, 2026. Compare Grok Bot’s shared Bots.
2. It checks at intervals. An urgent item can arrive late, and Anthropic says it may misjudge urgency.
3. It uses up your plan. Background checks count, so a Pro plan can run out sooner.
4. It is weak on Microsoft. Anthropic’s support article says Microsoft 365 is not ready, while its product page lists it. Slack works with limits.
5. It does not call or text. It also cannot see local files, and you cannot watch or take over its browser.
6. Some sites block it. It identifies itself as an agent, and some large sites refuse it.
7. Memory outlasts the connection. Reset memory when you disconnect an app.

Anthropic’s safety article also says page text still reaches the model, so a bad web page remains a risk. Keep your approvals tight. A preview can change, so hold off on building a core process on it.
