On September 8, Meta launched Muse, an artificial intelligence agent that chats inside WhatsApp, shops online, and pays on its own. For now, only in the United States.
In the same app, your business remains barred from using a general-purpose assistant for customer service, under risk of losing the number.
On the customer's side, a machine that talks about anything. On your side, a bot with limited scope. It's not a conspiracy: it's the difference between operating the platform and using the platform. But it changes what you need to have ready.
What Muse does
- It works in its own app, on the website, and inside WhatsApp conversations. Talking to it is like messaging a person.
- It shops and pays with Link, by Stripe. In more than a million stores that accept Link, it checks out instantly with the payment method the person already has saved.
- In other stores, Link issues a single-use virtual card, limited to that approved purchase.
- Facebook, Instagram, and Threads are linked automatically when they're already on the same Accounts Center. Other services, like Google Workspace, Ticketmaster, and OpenTable, are connected one by one.
- Free use up to 100 million tokens per week. Paid plans cost 20 and 100 dollars a month.
The rule that still applies to your business
Since January 15, 2026, Meta's artificial intelligence policy for the WhatsApp Business Platform bans general-purpose chatbots — the "assistant that talks about everything" — and allows only bots with a specific function: customer service, scheduling, order status, notifications, surveys. Those who violate it can have their number restricted or banned. We covered the full rule in AI on WhatsApp: Meta's new rule.
That rule hasn't changed with the launch. Muse is not a loophole for you.
What changes when the buyer is an agent
An agent doesn't ask "what's the price?" in a direct message and wait two hours. It reads, compares, and decides. What it finds in your operation now matters more than your sales copy.
- Visible pricing. A product with no published price becomes a product the agent won't consider.
- Delivery time and shipping that can be calculated without a conversation. If it depends on negotiating by message, the purchase doesn't happen.
- A structured catalog, with name, variation, availability, and terms in the same place.
- Fast response. The customer's agent tries another store while you're typing.
- Checkout that accepts a virtual card. This is the operational detail almost no one mentions: when the store doesn't use Link, the payment arrives as a single-use virtual card. If your system rejects virtual cards, requires manual approval, or asks the customer to "confirm by message," the sale dies at the end of the funnel, and you never even know it existed.
What to do before this reaches Brazil
Brazil is the largest WhatsApp market in the world, so the question isn't whether it arrives, it's when. The preparation is the same work that improves your operation today:
- Publish pricing for at least your best-selling items.
- Test your own checkout with a virtual card generated by your bank's app. If it goes through, you're ready for that part.
- Reduce time to first response, even if it's an automated, specific-function reply, which is what the rule allows.
- Make information machine-readable on your website: structured data, direct answers, nothing essential hidden inside an image.
- Don't put a general-purpose assistant on the business WhatsApp. It's still banned, and the number is what's at risk.
Those who were already preparing for AI-driven search don't need a new plan: it's the same work. We've already covered the automatic buyer in the AI that pays on its own and in your customer will show up with an AI in their ear.
The part we still don't know
Two honest points. Muse is new and limited to the United States, and launch products tend to promise more than they deliver in the first six months. And there's no public information on how Meta will handle, in the future, the conversation between a consumer's agent and a company's business number.
What's already a decision for today, and doesn't depend on either of those answers: published pricing, calculable delivery times, and a checkout that accepts automatic payment. That sells more even if the agent never shows up.
Building automated customer service within what the rule allows is what we do in chatbot with artificial intelligence.

Frequently asked questions
What is Meta's Muse?
It's a personal AI agent launched on September 8, 2026, that works inside its own app, on the web, and within WhatsApp conversations. It shops online, fills out forms, books trips, and pays using Stripe's Link. It's free to use up to 100 million tokens per week, with paid plans at $20 and $100 a month.
Can I now put a generic AI assistant on my company's WhatsApp?
No. Meta's policy for the WhatsApp Business Platform, in effect since January 15, 2026, still bans general-purpose chatbots and only allows single-function bots, such as customer support, scheduling, and order status. Muse's launch doesn't change that rule, and breaking it still risks having your number throttled or banned.
Is Muse already available in Brazil?
Not at launch. The rollout started in the United States, with iOS and Android apps and web access. Since Brazil is the world's largest WhatsApp market, it's worth preparing now, but no date has been announced.
How does an AI agent pay for a purchase in my store?
In stores that accept Stripe's Link, it completes the purchase using the payment method the shopper already has saved. In other stores, Link issues a single-use virtual card limited to that approved purchase. That's why it's worth checking whether your checkout accepts virtual cards without requiring manual approval.
What does my store need to have to sell to an agent?
Published pricing on your main items, shipping cost and delivery time that can be calculated without a conversation, a catalog with variations and availability in one place, a short time to first response, and a checkout that accepts automatic payment. Information hidden inside an image or dependent on back-and-forth negotiation falls outside what the agent compares.
Does this replace my human customer service?
Not in the short term, and preparing for it doesn't depend on that happening. The changes that make a store legible to an agent, like publishing prices and cutting response time, boost conversion with human customers today, even while the agent takes its time reaching Brazil.
