We tested Muse on an e-commerce purchase

Hello! The Agentic Commerce Club has never lived up to its name so well. This time, no classic newsletter: a video demo of an agent making a purchase for us.

5 million downloads in 22 days. Muse is Meta's personal AI agent, launched in the US on 8 September. What sets it apart from ChatGPT fits in one line: ChatGPT tells you what to buy, Muse buys it. It opens the merchant's site itself, compares, fills the basket and pays with Shop Pay or Link by Stripe, once you approve.

We tested it on a real purchase: a Manucurist nail polish for a friend's wedding.

What you'll see

  • 0:25 Muse opens the Manucurist site on its own, closes the pop-ups and compares prices.
  • 0:50 Coral dress, gold sandals: it recommends Gold Sand, “to echo the shoes”.
  • 1:35 The wall: to pay, you need a Shop Pay account. On day one, we gave up here.
  • 2:05 Four days later: a checkout error, and the billing address taken as the shipping address.
  • 2:30 Order confirmed: $20.63. Nothing is charged until we tap “Allow”.

Where does agentic commerce stand?

What works. An agent can now browse a real store, understand a real brief and place a real order, on the brand's own checkout, with you approving every payment. A year ago, that was a demo. Today, it's an app with millions of users.

What doesn't, yet. Paying is still a wall: you need the right wallet, and the first setup kills the moment. Agents are slow, verbose, and still make mistakes, like our shipping address. And the big players don't agree: Amazon blocks Muse, and ChatGPT pulled its own checkout this year.
