Claude Duet: What It Does and What to Delegate First

Claude Duet is worth joining the waitlist for if you already use Claude Pro, Max, or Ultra in the US and want routine work prepared for your review. Built on Anthropic's Claude Opus 5.5, it brings you a morning brief and keeps working across connected apps while you are away. Start with meeting preparation and draft replies, with a person checking the result before anything consequential happens. Anthropic's product page.

Verified against Anthropic's live product, pricing, announcement, safety, and support pages on November 2, 2026. This is a documentation-based assessment, with no signed-in Duet test.

What Is Claude Duet, and How Does It Work?

Claude Duet turns a message into ongoing work on a cloud computer. It is a proactive agent, meaning it can take steps toward a task and bring something to your attention without waiting for another prompt. Anthropic dates the research-preview announcement to October 21, 2026. Duet has its own browser and virtual machine, a computer hosted remotely, so your laptop does not have to stay open. Anthropic's announcement.

Think of it as an assistant who prepares the morning folder before you arrive. The useful handoff is specific: gather the material, identify what needs a decision, and bring back something you can check. A vague request to “run the business” gives you no clear standard for deciding whether the work is right.

Duet uses the memory, skills and connected apps already associated with your Claude account. A connector is the link that lets Claude access another service. That continuity reduces setup, but it also makes an access review worthwhile before you delegate business work. Without a fresh prompt, Duet can prepare the morning brief, draft replies, flag items that need you, and follow up on quiet threads. You can also assign a specific deliverable by text or voice. Duet setup guide.

What Should a Small Business Hand It First?

Give Duet work where a mistaken draft is easy to catch and cheap to correct. Anthropic lists morning briefs, inbox and calendar flags, reply drafts, meeting scheduling, briefs, decks and dashboards. It also describes finding unpaid invoices and preparing payroll for review. These are documented capabilities; their reliability still needs evaluation in your workflow. What Duet can do.

The distinction is the consequence of getting the result wrong. A missed detail in an internal meeting brief can be corrected before the call. A mistaken payment or an email promising a customer a refund has already changed the business once it goes out.

For a founder, start with a brief for the next investor or customer meeting. Ask for the unresolved questions and the source behind each material claim. The payoff to look for is less preparation work without more correction work.

For an operator, an invoice reminder draft is a useful later trial. Anthropic names Intuit QuickBooks and Stripe for invoice checks, and Gusto for payroll work. Keep payroll preparation behind a knowledgeable review: hours, reimbursements and employee details need checking against the underlying records before approval. Documented business integrations.

For a builder or CTO, choose an internal brief before a workflow that touches production systems. Treat the trial as a way to establish which handoffs your organization can review well. Access to a personal agent does not itself establish permission to connect company data.

Who Can Join the Claude Duet Waitlist?

The research preview is for US Claude Pro, Max, and Ultra subscribers, with a waitlist invitation required. Free, Team, and Enterprise are not eligible. Anthropic has not given a date for access outside the US or on its organization plans. Duet is available through standalone iOS and Android apps and on the web at claude.ai. Current availability.

Pro is $20 when billed monthly and Max is $100 per month before tax; Duet is included at no extra charge during the preview on Pro, Max, and Ultra. Plan prices and preview inclusion.

To join, use the product page's waitlist form, enter your existing Claude account email, choose your plan and phone type, and submit. Invitations arrive in waves, with no promised access date. Waitlist instructions.

Join now if you are already eligible, have a recurring administrative task, and can check the output. The case is strongest when preparation is the bottleneck and you remain available to make decisions.

Wait on adoption if you need a guaranteed response time or your workflow depends on Microsoft 365: Anthropic's Duet support page says that connector is not available yet. Do not infer readiness from a logo on a marketing page. Keep your current workflow if you need Team or Enterprise access to Duet; the separate Enterprise Chat/Cowork rollout does not grant a Duet invitation. Preview limitations.

Which Connected Apps Does Duet Support?

Duet uses apps you have connected in Claude, including Gmail, Google Calendar, Google Drive, Slack, Intuit QuickBooks, HubSpot, Docusign, and Calendly. Its Stripe connector supports invoice checks and reminder drafts. Anthropic also documents Gusto payroll work, approved LinkedIn job posts, Canva campaigns, and Shopify store work. Treat those as supported use cases to evaluate, not proof that every operation in each app is available. Duet setup guide and business examples.

Link and Shop Pay handle purchases you approve and are connected inside Duet; Link is separate from the Stripe connector. Slack has limits, Microsoft 365 is not available yet, and 1Password sign-in is still described as coming soon. A logo on the product page is not an availability guarantee. Integration limits and 1Password status.

You initiate each connection and can disconnect it. Switching off a shared connection removes access in both Claude and Duet. That stops new access; previously learned information remains until you reset memory. Review that retained context when ending a trial, not just the connector list. Account and memory controls.

What Does Duet Ask Before Doing?

Anthropic's setup guide says Duet is designed to show proposed messages, payments, signatures, and deletions and wait for approval. Reading, drafting, and preparation can happen independently; if you are unavailable, it can finish other parts and return to the pending decision later. Approval behavior.

The detailed safety guidance makes the boundary more precise. Approval frequency can vary, and your explicit request can itself supply consent to share private information. Do not assume a fresh confirmation screen for every routine action. Payments, deleting an order, and creating an account cannot use a standing “don't ask again” rule. Trading securities, transferring money between bank accounts, and accessing someone else's account remain off-limits even with approval. Duet safety controls.

Make that boundary explicit in the task itself. A useful first request could be:

Prepare a brief for my next customer meeting from the relevant email thread and calendar entry. Separate confirmed facts from assumptions, link to the source material, and flag anything you could not find. Draft any follow-up for my review. Do not send messages, make payments, sign documents or delete anything.

This suggested instruction defines both the deliverable and what must come back to you.

Review the proposed action, not just the summary above it. For an invoice reminder, open the invoice and verify that payment has not arrived elsewhere. For a meeting invitation, check the attendees and time zone. A clear approval screen cannot compensate for a reviewer approving the wrong thing.

How Background Work Uses Your Claude Limits

Duet draws on the same plan allowance as your other Claude work. Morning briefs and background checks count, and bigger deliverables can require more model turns. Anthropic says it checks connected accounts every few hours because nonstop checking would consume limits faster. How Duet uses the plan.

Pro and Max have a session allowance that resets every five hours and a weekly allowance. Verified Ultra accounts have no five-hour limit, but weekly limits still apply. These are usage limits, not a promised number of finished Duet tasks. Current plan limits and Anthropic's usage-limit explanation.

For a Pro subscriber who already reaches the limit during ordinary work, background activity creates a practical tradeoff. Start with a narrow task and observe the remaining allowance before expanding to recurring briefs, decks and dashboards together. Max and Ultra subscribers should use the same method; a larger allowance still needs to cover the work they already do.

Do not plan around a made-up conversion such as “one dashboard equals a certain number of messages.” Judge the trial by whether the completed work is useful, how much checking it needs, and whether it crowds out higher-priority Claude work.

What's Overhyped: Proactive Does Not Mean Continuously Watching

The dangerous assumption is that silence means nothing needs attention. Anthropic says Duet can misread a thread, misjudge urgency, or miss an item between check-ins. Stated limitations.

Imagine a client changes tomorrow's meeting location after a check. Even a perfectly accurate earlier brief cannot contain a message that arrived later. Keep calendar alerts and direct customer escalation paths in place while you evaluate Duet. Give someone responsibility for checking deadline-sensitive work independently.

Approval and detection solve different problems. Approval gives you a chance to stop the wrong outgoing action. It does not reveal an incoming item that the agent never surfaced. The trial therefore needs two review questions: was the prepared work correct, and what important work did it miss?

You also cannot currently watch or take over Duet's browser, according to the support guide. That makes tasks requiring live supervision a poor first handoff. Browser limitation.

Where Duet Fits Beside Claude Cowork and Claude Code

Claude Cowork, Anthropic's task workspace for files and connected tools, handles assigned and scheduled work and can continue after your laptop closes. Use it when the deliverable is known, such as a recurring report. Duet's distinctive emphasis is bringing you priorities and follow-ups through an ongoing assistant relationship; it remains a separate app during the preview. Cowork capabilities and Duet's current relationship to Claude.

Since October 23, 2026, the unified Chat and Cowork experience has been generally available for Enterprise: a conversation can move from a quick answer into cloud work and return a finished document, analysis, or deck. Anthropic also published Duet's detailed safety guidance that day. These are separate changes; Enterprise unification does not make Duet available to Enterprise users. Enterprise announcement and Duet safety update.

Claude Code is Anthropic's coding agent for software changes, bug fixes, and testing. Keep a repository change in that development workflow. Claude Code's capabilities and our Claude Cowork vs Claude Code comparison explain the division. Choose by the work and the review process, rather than assuming every task belongs in the newest app.

Which Admin Controls Apply?

Duet currently has personal account controls: connected-app access, memory settings, task visibility, and approvals. Its eligible plans do not include organization-level connector administration, role-based access, or audit logs. A business should not assume the Enterprise controls below govern an employee's personal Duet account. Duet account controls and plan administration features.

For unified Enterprise Chat/Cowork, an Owner or Primary Owner can enable Organization settings > Capabilities > Chat and Cowork unified. Chat and Cloud code execution and file creation must also be enabled. Access can be limited through custom roles, but the organization switch grants access to standard roles: move people outside the pilot into restricted custom roles before enabling it. Admins also control connectors, network access, scheduled tasks, remote control, sharing, and approval modes. Enterprise setup guide.

Efficient mode limits the unified experience to Sonnet and Haiku models. Model permissions, spend limits at organization, group, and member levels, and pooled group budgets help govern usage. These are Cowork/Chat controls, not Duet settings. Enterprise usage controls.

For eligible existing organizations that have not made an explicit choice, Anthropic's guide schedules automatic enablement for November 16, 2026; Keep disabled preserves the choice to wait. Organizations using zero data retention, a HIPAA-ready configuration, or customer-managed encryption keys are currently excluded. Check those conditions before scheduling a pilot. Rollout conditions.

What About OpenAI Dots and Meta Muse?

OpenAI Dots and Meta Muse are comparable at the level their makers document: agents that keep advancing work on their own computers. OpenAI describes Dots using a cloud computer, browser and connected apps, with rules for what may proceed independently. Meta describes Muse continuing after the app closes and checking before actions such as email or purchases. That establishes overlapping capability, not equal reliability, access or approval behavior. For a founder already organized around Claude, the sensible starting point is the smallest useful handoff inside that existing account. If Dots is also under consideration, the separate Is OpenAI Dots Free? guide covers its access and allowance question.

Your First Week Checklist

Switch Duet on for a small business pilot only after an eligible US account receives an invitation, the business permits that account to access the chosen data, and someone owns review. Start when meeting preparation or inbox triage is a recurring burden and mistakes are reversible. If you need centrally managed Team or Enterprise access, use the approved Cowork workflow and wait for Duet's organization support.

During the first week, track useful drafts, missed urgent items, false alarms, approval requests, usage consumed, and time spent correcting the work. Expand only when preparation saved exceeds review work and the missed items are tolerable for that workflow. This is a suggested evaluation, not a reported Duet test.
