Meta announced retail partnerships for Muse, its standalone personal AI agent app, with Walmart, Gap, Sephora, Expedia, Wayfair, Best Buy and other companies on September 23, shortly after the service launched. Unveiled on September 8, 2026, Muse is designed to perform multi-step tasks, including searching retail sites, recommending products, preparing purchases and completing orders with user approval. Transactions run inside Meta’s Muse Secure VM, a sandboxed environment, and require permission before an order is placed. Payment support expanded from Stripe Link at launch to Shopify Shop Pay around September 21-22 and PayPal around September 22. Muse reached between 2.5 million and 2.8 million U.S. downloads in its first two weeks and rose to the top ranks of the App Store. Amazon blocked the agent from accessing its platform in mid-to-late September, citing consent and credential-security concerns. Shoppers continue to express concerns about price-gouging as companies increasingly use AI-driven dynamic pricing and similar practices. Muse offers free access alongside paid tiers priced at $20 and $100, while Mark Zuckerberg has indicated that Meta intends to rely primarily on small transaction fees. Meta has signaled that additional retail connectors and payment options are planned.
