Mark Zuckerberg shipped Muse for Mac on September 17, closing a nine-day sprint that put Meta’s personal AI agent on iPhone, Android, WhatsApp, the web, and macOS. The distribution surface is the story. No consumer agent has ever launched with this much shelf space on day one.

“Muse for Mac is out today! It works across apps, files, calendar, notes, and messages on your computer,” Zuckerberg said. Meta describes an agent that can send email, book travel, open a browser, fill out forms, and negotiate on the user’s behalf. At checkout it uses Link by Stripe with a one-time-use card so real card details stay hidden. Bloomberg’s rundown adds tennis lessons and school permission slips to the task catalog.

TechCrunch notes the connector map: email, calendars, payments, health and fitness, smart home, dining, shopping, music, events. When no API is available, Muse falls back to the browser. Meta says it ships with built-in connectors for several services, with plans to add more over time.

For a founder-led B2C business, that sentence is the whole game. Launch-category connectors will capture disproportionate agent traffic in the first quarter of adoption, the same way early App Store categories in 2008 locked in incumbents who are still there. If your restaurant, studio, or shop lives inside an OpenTable-style connector Muse already talks to, you’re in the funnel. If it doesn’t, Muse has to browse to you, and browsing means your site has to be legible to an agent: clean product data, real prices, no captcha wall, no pop-up asking for a birthday before someone can book.

This isn’t a one-off. Meta’s WhatsApp sales-agent push and Apple’s Siri AI rollout on iOS 27 point at the same layer. The customer-acquisition surface is quietly moving from search result to task completion. The businesses that ranked well on Google in 2015 aren’t automatically the ones agents can transact with in 2026. It’s a different substrate, and it’s being paved now.
