How to Use Muse on WhatsApp: Your Agent Inside Your Messages
Muse works inside WhatsApp, so delegating a task is as simple as sending a message. What it can do there, how approvals work, and where the limits are.

The shortest path to Muse is an app already on your phone. Muse works inside WhatsApp, so handing off a task looks like texting a person who happens to be very good at errands.
Every other AI assistant asks you to come to it: a new app, a new tab, a new habit. Muse also lives inside WhatsApp, which most people open dozens of times a day. You message your agent the way you message a person, in the same thread style, with the same informality, and the agent goes off and does the work. No new interface to learn is a small thing until you count how many good tools die waiting for a new habit to form.
What Using Muse on WhatsApp Looks Like
You send a message describing the outcome you want: find three flights home for Thanksgiving under a price, reorder the coffee beans from last time, pull together what your landlord said about the deposit. Muse treats the message as a job, not a question. It browses, compares, and assembles the result, then reports back in the chat.
The work does not happen on your phone. Muse runs tasks on a dedicated virtual machine in Meta’s cloud, so a job keeps going after you lock your screen or switch apps. When it reaches a step that matters, it comes back to you in the thread. Every purchase and every outgoing message needs your approval first, and a separate Sentinel agent approves anything Muse sends to the internet. Meta says the agent has no visibility into your passwords or payment details, which matters when the front door to the agent is a chat app.
Voice works too. Voice replies in WhatsApp have been part of Muse for months, and talking suits the format: a rambling sixty-second voice note is a perfectly good task brief. Our voice mode guide covers when speaking beats typing and the phrasing that works best.
Getting Set Up
Muse on WhatsApp runs through your Muse account, so the requirements are the account requirements: you need to be in the US or Canada and 18 or over. If you do not have an account yet, our guide on how to download Muse covers the app, the web version, and the invite code worth 1 billion tokens that you need to redeem within 48 hours of joining.
WhatsApp on its own gives Muse a chat window. Its reach grows when you connect your other apps: connectors let Muse read your calendar, check a storefront, or work in tools like Notion and Slack as part of the same task. The setup flow and the permission choices that matter are in our walkthrough on connecting Muse to your apps.
What It Is Good For
The tasks that fit WhatsApp are the ones you would otherwise text a capable friend about. Quick errands with a clear finish line: book the thing, reorder the thing, find out the thing. Follow-ups work well in a thread, too, because the conversation is already there. Ask for the cheaper flight, change the date, then approve the booking, all without leaving the chat.
Longer jobs benefit from the same setup. A task you start from your couch keeps running in the cloud while your phone is in your pocket, and Muse reports back in the thread when it finishes or when it needs a decision. Scheduled work fits the pattern as well: a morning message with what needs your attention beats another app badge to clear.
The Limits
Availability is the first one. Muse is US and Canada only, and the account check happens at sign-in, so a WhatsApp number from another country does not open a side door. Meta has named no dates for other regions.
Approvals are the second, and they are a feature. Muse will not spend your money or send a message in your name without asking, which means a task can pause mid-thread waiting for your reply. That pause is the price of delegating safely, and for anything involving payments it is a fair trade. Our look at Muse’s Sentinel permissions explains how the approval layers divide read access from write access.
Finally, keep the channel in perspective. WhatsApp is a way in, not a different product. The same account, the same token balance, and the same limits apply whether you talk to Muse in WhatsApp, the phone apps, or the web. If you are already a WhatsApp person, that is the point: your agent is finally reachable in the app you never stopped opening.
