Quick take: Claude Duet is a proactive AI assistant that does tasks in the background and checks in with you, rather than waiting for every prompt. It launched as a research preview in late 2026.
People keep asking one question this month, which is simple. What is Claude Duet? In short, it is a new app from Anthropic that acts like a quiet helper working in the background. Most AI tools sit still until you type something. Duet is different. It can start tasks on its own, send you a short morning update, and only ping you when something really needs your eyes. Here is a clear look at what it does and whether it is worth your time.
How Claude Duet is different from a normal chatbot
The easiest way to understand Duet is to compare it to the chatbots you already know. A normal chatbot answers when you ask. Duet keeps working even when your laptop is closed, because it runs on its own machine in the cloud. That small shift changes how you use it.
| Normal chatbot | Claude Duet | |
|---|---|---|
| When it works | Only when you type | On its own, in the background |
| Check ins | Never | A short morning update, then only when needed |
| Your device | Must be on | Can stay off while it works |
| Best at | Quick answers | Longer tasks across your apps |
What Claude Duet can actually do
Duet connects to thousands of tools through the Claude Marketplace, like email, chat, accounting and payment apps. Once connected, it can handle real work for you, such as:
- Draft and tidy up your emails before you send them.
- Set up meetings and keep your calendar in order.
- Build simple dashboards and reports from your data.
- Prepare rough money forecasts and summaries.
- Put together a basic web app or prototype.
Good to know: Before Duet sends a message, makes a payment, or deletes anything, it shows you the plan and waits for your yes. Moving money is blocked even if you approve it, which is a safety choice by Anthropic.
Who can use Claude Duet right now?
At launch, Duet is a research preview. That means it is early and rolling out slowly. For now it is open to Pro and Max subscribers in the United States through a waitlist, and it runs on iPhone, Android and the web. If you already use Claude, Duet picks up your saved memory, skills and app links, so there is little setup. Team and business plans are expected later.
Is Claude Duet worth trying?
If you spend hours each week on small, repeat tasks, a proactive agent like Duet could save you real time. It is still early, so expect rough edges and a careful rollout.
