What is Claude Duet for Browser?

A Chrome extension that puts an AI agent and assistant in Chrome’s side panel. It answers questions about the page you’re on, compares answers from two AI models in Duet mode, runs research with sources and — as an agent — clicks, types and fills in forms in your tab to finish tasks you describe.

Is it free?

You can try it with one free request. After that, Pro unlocks unlimited agent tasks, chats, Duet and research. Pro is $4.99 a week (with a 3-day free trial for new subscribers), $9.99 a month or $39.99 a year.

Can it create images?

Yes. Switch the message box to Image, describe the picture and pick a shape (1:1, 3:4, 4:3, 9:16 or 16:9). You can also attach up to 3 photos as a reference, for example to change the background or the style. Each picture counts as one request, and only if it was actually made. Pictures are kept in your browser, not on our servers, and you can download them in full size.

Can I send a photo?

Yes. In Chat and Duet modes you can attach up to 3 photos per message (button, paste or drag-and-drop) and ask about them. The extension resizes them and removes metadata such as location before sending; they aren’t stored on our servers, only a small preview stays with the chat in your browser.

Which AI models does it use?

Claude models from Anthropic, and in Duet mode also a GPT model from OpenAI, through their APIs. Model versions may change as providers release updates.

Is it made by Anthropic?

No. Claude Duet is an independent product and is not affiliated with, endorsed or sponsored by Anthropic or OpenAI. Claude is a trademark of Anthropic; GPT is a trademark of OpenAI.

Can the agent buy things or send messages on its own?

No. It stops and asks before sending, submitting, publishing, paying, buying, booking, deleting, signing in or changing account settings. It never types into password or payment fields.

Where are my chats stored?

In your browser. Chats, memory, calendar, automations and settings are stored with Chrome’s local storage on your device. Our server keeps only a random install ID, request counters and subscription records.

Does it read every page I visit?

No. A page is sent only together with something you start: a message while the page switch is on, a page action like Summarize, the right-click menu, or an agent task.

Which languages are supported?

The interface is available in English, Spanish, Italian, German, French, Portuguese (Brazil), Russian, Hindi, Japanese and Chinese. The AI can answer in many more languages.

How do I cancel?

In the extension: Settings → Manage subscription. Cancellation takes effect at the end of the current billing period. Uninstalling the extension doesn’t cancel the subscription.

Does it work in other browsers?

It’s built for Google Chrome on desktop. Other Chromium browsers may install Chrome extensions, but we test and support Chrome.

What counts as a request?

One chat message, one Duet question (both answers together), one agent task however many steps it takes, one research report or one automation run.

How does the free trial work?

New subscribers on the weekly plan get 3 days free. If you don’t cancel before the trial ends, the weekly plan starts and renews until you cancel. One trial per person.

Does it read every page I visit?

No. A page is sent only together with something you start: a message while the page switch is on, a page action like Summarize, the right-click menu, or an agent task.

Can I get a refund?

Payments are handled by Dodo Payments, our merchant of record. Refunds follow their policy and the law in your country. See Cancellation & refunds.

Can I move Pro to another browser?

Yes. Use “Restore purchase” in the extension with your checkout email and order ID.
