Meta's Muse launched two weeks ago as a personal AI agent you hand tasks off to rather than chat with. Since then it's become one of the biggest product stories of the year: download numbers that outpace ChatGPT's early days, a Shopify and Instacart partnership that wires Muse straight into checkout, and an Amazon block that exposes exactly what's at stake when an agent skips the shelf.
Mike Belsito connects the dots back to a question the show posed in August, what will it actually take for non-tech consumers to trust an AI agent with something real, and argues Muse may be answering it by accident.
Key takeaways
— In a 12-day window, Muse pulled 1.8 million iOS downloads in North America against ChatGPT's 1.3 million at its 2023 launch — though Mike flags the comparison as skewed, since this time the public already understands what AI is.
— Shopify wired Shop Pay directly into Muse's checkout on 21 September, and Instacart followed a day later, letting Muse buy from either platform without opening the app. Shopify's stock jumped 11% on the news.
— Amazon blocked Muse from its store that same week, accusing Meta of capturing customer credentials without disclosure. Meta maintains Muse never sees passwords or payment details because credentials sit in secure storage it can use but not view.
— Amazon's sponsored-ads business brings in $68 billion a year, and it depends on shoppers scrolling past paid placements that an agent checking out directly would skip entirely.
— Muse is solving the distribution half of the "agentic trust gap" that Browser Company co-founder Josh Miller described in August: rather than winning as a better standalone app, it's showing up inside checkout flows exactly when people are already trying to buy something.
— Every person who lets Muse handle a multi-step task without watching each step is practising a habit they'll bring to work on Monday, which should lower the bar for getting your own users to trust an agent with something real.
