The chatbot stops at the sentence
Ask a chatbot to book the train and you get instructions. Ask an agent and the point of the product is that it opens the site, fills the form, and stops only when a payment or a send needs you. That is why this month feels crowded. Meta shipped Muse on 8 September 2026. xAI opened Grok Bot as named teammates with a shared computer. The category finally has products a person can message without standing up a server.
Four parts, every time
Whatever the brand, the machine has the same organs. A computer, usually a virtual machine, so the agent can use a browser and files without living on your laptop. A way into your accounts: connectors where an app has an API, and ordinary computer use where it does not. Memory, so Tuesday's correction still applies on Friday. And a permission boundary, so sending, paying, and deleting are not the same action as reading.
Miss any one of those and you are back to a chatbot with extra steps. The computer without a boundary is how a demo becomes an incident. The memory without a computer is a notes app.
Personal describes the relationship
Personal describes who the agent is for, not a single logo. Muse puts the relationship in one steward that learns a single life, and for now that product is rolling out in the United States. Grok Bot splits the relationship across named teammates that share one computer, which suits work that already has lanes. People who want the same shape on hardware they administer are looking at open-source agents they run themselves.
The useful question is which boundary you want. One steward for your own accounts. A small roster for shared tools. Or a box you run, where you also own the failure modes.
Start smaller than the demo
The demos show a week of errands collapsing into one message. The sane first job is narrower: read an inbox and draft, watch a calendar, file a receipt, summarize a thread. Widen access after the agent has been quietly correct for a while.
An agent with your payment method and no approval step is not a productivity gain. It is an employee you cannot audit. Give it a job you can check, then give it the next one.
