Meta added three major U.S. retailers to Muse, its personal AI agent, giving the tool direct purchase access across groceries, apparel, and electronics while relying on sandboxed payments and one-use cards.
Muse now has direct shopping access to Walmart, Gap, and Best Buy, expanding its ability to complete purchases across key retail categories.
The agent runs in a sandboxed Muse Secure VM, uses Stripe Link with single-use cards, and partners with Shopify and PayPal for broader checkout support.
Meta’s AI infrastructure investment and a roadmap for larger models (codename Watermelon) indicate this integration is part of a larger commerce strategy.
Meta announced that Muse, its standalone personal AI agent, can now shop at Walmart, Gap, and Best Buy. The integration was disclosed by Meta executive Alexandr Wang. These three retailers cover broad consumer categories—groceries, apparel, and electronics—so the update materially increases the kinds of purchases Muse can complete on a user's behalf.
Muse launched on September 8, 2026, as an agent designed to perform tasks such as sending emails, booking reservations, filling forms, and making purchases. It runs inside the Muse Secure VM, a sandboxed environment Meta describes as protecting user data and payment details. For transactions, Muse uses Stripe Link and generates single-use cards for each purchase. Meta has also integrated Shopify and PayPal into the payment mix to expand checkout compatibility.
The agent uses Muse Spark 1.3, a model with a one-million-token context window. Meta has outlined a future model codenamed Watermelon that would follow Spark 1.3. Muse is available to U.S. adults aged 18 and older. There is a free tier, but the paid tiers are where most functionality is concentrated: Power at $20 per month and Maximum at $100 per month. Users can access Muse through a dedicated app, a web interface, and WhatsApp integration. Meta has discussed adding AI glasses functionality later.
Meta reported early download traction: between 2.5 million and 2.8 million downloads in the first two weeks, and top rankings on the U.S. iOS App Store. The company has promoted Muse through social campaigns and TV advertising, including a consumer-facing initiative called the #MuseMoneyChallenge.
Why this matters for retail and marketplaces
Meta's architecture emphasizes a sandboxed workflow and single-use payment cards to limit long-lived exposure of credentials. Partnerships with Stripe, Shopify, and PayPal broaden where Muse can transact. These technical choices matter because they affect the risk surface for financial data and the mechanics of how a third-party agent completes purchases.
Track merchant and platform responses: whether more retailers open direct integrations, whether Amazon or other marketplaces block access, and how Shopify's one-tap checkout adoption with Muse evolves. Monitor Meta's AI infrastructure spend and product roadmap—public figures referenced a multi-hundred-billion-dollar investment in AI infrastructure and a next-model plan called Watermelon—as indicators of continued investment that could expand Muse's capabilities and reach.
The artificial intelligence agent will be able to make purchases for users on all Shopify stores but won’t have access to Amazon products or retailers.

Let an AI agent go to town with your credit card? You must be nuts. But that’s the pitch — and the appeal — of Muse, the new agentic assistant from Meta that’s turned into an unlikely AI hit. I’ve been playing with Muse for the past few weeks and, until a couple of days ago, I wasn’t too impressed. To me, it looked lik
