**Claude Duet is an autonomous AI agent (programs that carry out multi-step tasks for you on their own) running asynchronously in the cloud; while included at no extra charge for US Pro and Max subscribers, its background work consumes your plan's standard usage limits.**

Anthropic announced on Oct. 21, 2026, the research preview and waitlist for **Claude Duet**, its autonomous personal agent service. Unlike traditional chatbots that wait for user prompts, Duet operates on a dedicated virtual machine in the cloud, monitoring inboxes and calendars, preparing deliverables, and reaching out only when decisions or approvals are needed.

## Who Can Use It and What It Costs

There is no extra subscription fee for Claude Duet during the research preview. However, access is limited to individual paid subscribers with US-based accounts.

| Plan | Duet Preview Access | Extra Cost | Usage Limits |
| --- | --- | --- | --- |
| Free Accounts | No | - | - |
| Claude Pro | Yes (US accounts) | None | Consumes Pro limits |
| Claude Max | Yes (US accounts) | None | Consumes Max limits |
| Team / Enterprise | No | - | - |

Team and Enterprise organizational plans are excluded from this initial preview. Anthropic indicated plans to expand to teams later, but the current rollout focuses on individual professionals and solo business operators.

## What It Does in the Background and Where It Pauses

Users interact with Duet through standalone iOS and Android apps or on the web at claude.ai, messaging it in plain language like a colleague. Because Duet runs on a dedicated cloud virtual machine, tasks continue running even if you close your browser or turn off your phone.

Its core capabilities divide into daily assistance and operational business support:

- **Daily coordination:** Delivering morning briefs summarizing overnight emails and upcoming calendar commitments, alongside draft replies
- **Document creation:** Generating initial drafts of documents, spreadsheets, presentation decks, and dashboards
- **Business administration:** Tracking unpaid customer invoices, drafting payment reminder notices, preparing payroll data for review, and organizing contracts for signature

Duet is not permitted to execute sensitive actions autonomously. For high-stakes operations—such as sending outgoing emails, processing payments, or modifying records in external services—it pauses and waits for explicit user confirmation on screen before proceeding. It also carries over your account's existing Claude memory, custom skills, and connected application integrations.

## Shared Usage Limits and Current Limitations

The most critical operational constraint is usage accounting. Because Duet does not charge a separate subscription fee, its background checks and multi-step executions count against your existing Claude Pro or Max plan limits.

Building extensive financial models or slide decks consumes significant model turns and background compute. Because these tasks share your normal conversational quota, intense background activity can temporarily restrict your access to interactive Claude chats.

Anthropic explicitly noted three primary limitations during this preview phase:

- It may misread the conversational nuance or context of complex email threads.
- It can misjudge what is genuinely urgent versus what can wait.
- It may not detect urgent developments that arrive between scheduled check-in cycles.

## What to Watch

- How background agent activity affects daily usage quotas for Pro and Max users, and whether Anthropic introduces dedicated background add-on packs
- The timeline for rolling out Duet to international subscribers and corporate Team/Enterprise accounts
- How competing proactive agent products from OpenAI and Google respond in the standalone agent category
