Meta Launches Muse, a WhatsApp AI Agent That Shops, Emails and Negotiates for Users

Meta's new Muse agent handles purchases, travel bookings and email from inside WhatsApp, with payments routed through Stripe's Link and a separate Sentinel agent vetting every action before it goes online.
Meta introduced Muse, an AI agent that lives inside WhatsApp and carries out shopping, travel booking and email tasks on a user's behalf, the company said this week. Purchases are settled through Stripe's Link, giving the agent a direct checkout path rather than handing users off to another app. The move puts Meta out in front of OpenAI on agentic commerce, an area where ChatGPT's operator has pulled back.
The payment piece is the sharpest differentiator. OpenAI ended its direct checkout feature inside ChatGPT, leaving the assistant able to research products but not complete a transaction. Muse closes that loop through Stripe's Link wallet, which stores card details and lets the agent pay without exposing credentials to the merchant. For Meta, that means WhatsApp stops being just a messaging layer and starts functioning as a storefront and a travel desk.
Negotiation is another piece Meta is advertising. According to the company, Muse can haggle over prices rather than simply accepting listed rates, a capability that turns routine purchases into something closer to a delegated errand. The agent also drafts and sends emails, though Meta has not detailed how it handles account access or which mail providers are supported. Those gaps matter because an assistant that acts on your behalf needs either broad permissions or a lot of trust.
Meta has paired Muse with a second system called Sentinel, which reviews each action before it reaches the internet. Sentinel effectively sits between the agent and the outside world, screening requests for anything that looks unsafe or out of scope. That two-agent design mirrors a broader industry pattern, where a capable model is boxed in by a narrower monitor with veto power. It also gives Meta a story to tell regulators and advertisers about control.
The launch lands as competition over consumer AI agents intensifies. Google, Amazon and a crop of startups are all pushing assistants that transact, and each is wrestling with the same problems: payment liability, fraud, and what happens when an agent gets a price wrong. Meta's advantage is distribution. WhatsApp counts billions of users, so Muse does not need to win a download battle to reach scale.
What remains unclear is how Meta will monetize Muse and whether merchants will accept an agent that negotiates against them. There is also the question of data, since an agent that reads email and buys goods sees a lot. Meta has not said when Muse will exit testing or which countries get it first, and those details will shape whether the launch is a real shift in how people shop or a demo that stalls.
