Most of the talk about AI and shopping has been about search: people asking an assistant what to buy. This is a step further. The assistant can pick the item and get to the payment step on the person's behalf.
That is worth understanding properly, so here is exactly what Anthropic announced, without filling in the gaps with guesses.
What Anthropic Announced
Claude Duet is a new app built on Claude Opus 5.5. It runs on iOS, Android and claude.ai. It can send morning briefs about important items across the apps a person connects, keep an eye on their accounts for anything urgent, and take on tasks from simple admin like scheduling meetings up to bigger projects. It works in its own browser in the cloud, so it can keep going while the person is offline.
For online stores, the important part is how it buys things:
The assistant does the task in a browser of its own in the cloud, so it can keep going while the person is offline.
Before buying, it checks with the person that this is the right item.
It pays with Stripe's Link or Shopify's Shop Pay. Link asks the person to approve the spend, and they are notified before any payment goes through.
The person stays in charge. Anthropic says the assistant asks for approval before sending messages, making payments, signing documents or deleting content, and has a safety check meant to block it from sharing card numbers and government IDs.
It is a research preview for now. People join a waitlist, starting with Pro and Max subscribers in the U.S., and it shares usage limits with other Claude features.
What This Means for a Small Online Store
Because it checks out with Shop Pay, a Shopify store with Shop Pay turned on is already a store this kind of assistant can buy from.
What changes is who is reading your product page. When the "shopper" is software working for a person, it relies on what your page actually says. Clear product names, accurate prices and stock, and a checkout that works matter even more.
A person shopping
- Visits your store and browses
- Reads your product page with their own eyes
- Pays at your checkout
An assistant shopping for a person
- Does the task in its own browser
- Relies on what your page says about the product
- Confirms the item, then the person approves the spend through Shop Pay or Link
What Is Worth Checking This Week
- Product names. Make sure each name says plainly what the item is.
- Prices and stock. Make sure what your page shows matches what you actually have and charge.
- Shop Pay. If you are on Shopify, make sure Shop Pay is on and your checkout works from start to finish.
At Balay ni Bruno & Co. we build and run Shopify stores for our clients. We have not used Claude Duet, so we are not going to claim results from it. What we can say is that clean, accurate product details and a working checkout have always been the groundwork of a store that sells, and now software shoppers read them too. Google is changing shopping as well: read what Google Universal Cart means for your store.
