Meta's Muse AI agent books travel, makes purchases, and sends emails through WhatsApp, with payments on Stripe's Link and a Sentinel security agent vetting every action.
Meta has unveiled Muse, an AI agent that operates inside WhatsApp and takes on practical errands for its users. The agent can book travel arrangements, complete purchases, and draft and send emails on a person's behalf. Muse is also built to negotiate prices, extending its remit beyond task execution into the kind of transactional back-and-forth that has traditionally required human involvement.
A defining element of the launch is its commerce plumbing. Muse ships with a payment feature that runs through Stripe's Link, meaning purchases the agent initiates can be settled through the payments company's checkout infrastructure. By embedding that transactional layer directly into WhatsApp, Meta keeps the full arc of agentic shopping — request, negotiation, and payment — inside a single messaging thread.
Meta has paired the agent with a dedicated safeguard. A separate security agent, called Sentinel, monitors every action Muse takes before it reaches the internet. The arrangement positions Sentinel as a checkpoint between the assistant's autonomous decisions and the outside world, an oversight layer that reviews each step of shopping, emailing, and negotiating before anything leaves the app.
The launch also carries competitive weight. Meta's move places it ahead of OpenAI, which stopped its direct checkout feature in ChatGPT. Where OpenAI has retreated from letting its assistant complete transactions directly, Meta is advancing an agent that not only transacts but haggles on a user's behalf, with Stripe's Link handling the payment side of each purchase.
The combination of task execution, price negotiation, integrated payments through Stripe, and a dedicated security monitor makes Muse one of the more complete agentic commerce offerings to reach a mainstream messaging app.
