Meta is putting serious effort behind Muse, its new personal AI assistant, and the app is already getting plenty of attention. Muse launched on September 8, 2026, and within just a few weeks, it had already reached millions of downloads in the United States and Canada. Meta is now using its huge reach across Facebook, Instagram and WhatsApp to put Muse in front of even more people.
The timing is important because Meta does not seem to be treating Muse as just another chatbot. The company wants Muse to become a personal AI agent that can do things for people, rather than simply answer questions. At Meta Connect 2026, the company announced several new features that could allow Muse to work with email, calendars, shopping services, computers, smart glasses and other apps.
With the app growing quickly and Meta pushing it across its massive family of platforms, the company appears to be making a serious attempt to turn Muse into one of the biggest consumer AI products in the market.
What Is Meta Muse?
Muse is Meta’s new personal AI agent designed to help people complete everyday tasks. Unlike a basic chatbot that mainly gives you answers, Muse is designed to take action on your behalf.
For example, Meta says Muse can help users manage tasks and projects, create plans, interact with services and work across different apps. It runs through what Meta calls the Muse Secure VM, a dedicated computer environment with its own browser that allows the AI to carry out tasks while keeping certain user information protected.
The bigger idea is simple. Instead of opening several different apps to complete a task, you could tell Muse what you want and allow the AI to handle much of the work.
That puts Muse in the growing category of AI agents. These are AI systems that are designed not only to talk to users but also to perform actions for them.
Muse Is Growing Very Quickly
One of the biggest reasons Muse is attracting attention is its early growth.
According to Sensor Tower estimates reported by TechCrunch, Muse had passed 2.5 million downloads earlier in the week. By Thursday, the estimate had increased to more than 3.4 million downloads. Other research companies gave different numbers, with Apptopia estimating 4.3 million downloads and Appfigures estimating about 2.3 million.
These numbers are estimates, so they should not be treated as exact official figures from Meta. However, the different estimates all point in the same direction, Muse is attracting a large number of users shortly after launch.
The app is currently available in the United States and Canada, which makes the early numbers even more interesting. Meta has not yet made Muse available everywhere, so its potential user base could become much larger if the company expands to more countries.
Muse has also performed strongly in app stores. It reached the top of the U.S. App Store on September 18 and the top of the Google Play Store on September 19, according to Sensor Tower data.
Meta Is Using Facebook and Instagram to Promote Muse
Meta has something that many AI startups do not have, billions of people already using its apps.
The company is taking advantage of this by promoting Muse across Facebook, Instagram and WhatsApp. This gives Meta a huge distribution advantage because it can introduce Muse to people who may not have been actively searching for a new AI assistant.
TechCrunch reported that Meta started showing its own ads for Muse just one day after the app launched. Within 10 days, Muse had received more of Meta’s own promotional advertising across its platforms than Facebook, Instagram and WhatsApp.
Meta is also promoting Muse outside its own platforms. The company has advertised the app across services and networks including Reddit, TikTok and YouTube.
But there is an important detail here. Muse’s growth cannot simply be explained by advertising. Sensor Tower estimated that ads promoting Muse accounted for only about 6% of its ad impressions between launch and September 19. That suggests that people are also finding and downloading the app through other channels.
Meta Is Building More Features Into Muse
Meta Connect 2026 showed that the company has much bigger plans for Muse.
One of the upcoming features is a digital avatar that users can talk to through video. Instead of communicating with a faceless AI, users will eventually be able to have live conversations with an animated version of their Muse assistant.
Meta is also bringing Muse to its smart glasses. This could allow people to speak to their AI assistant without taking out their phones. For example, Meta says Muse could help with things such as workouts, logging meals, booking appointments and buying products.
The company also wants Muse to work on Mac computers. This could allow users to tell Muse to perform tasks on their computer while they step away.
That is a major change from the way many people currently use AI. Instead of asking an AI to explain how to do something, users could potentially ask it to actually do the task.
Muse Could Become an AI Personal Assistant
This is where Meta’s plans become more interesting.
Meta is working on giving Muse its own email address. The company says users could eventually add Muse to an email conversation or forward emails to the AI so it can handle tasks on their behalf.
The company is also adding connections to shopping and business services. Meta has announced partnerships involving companies such as Shopify, Stripe, Best Buy, Gap, Sephora, Walmart and Wayfair.
Muse is also expected to connect with services such as Expedia, GitHub, Notion and other platforms.
Imagine telling an AI assistant that you need a new laptop, giving it a budget and asking it to compare available options. Instead of simply giving you a list of websites, an AI agent could potentially search stores, compare products and help you complete the purchase.
That is the type of experience Meta appears to be building with Muse.
Amazon Has Already Blocked Muse
The rapid growth of Muse has not come without problems.
Amazon has blocked Meta’s Muse agent from shopping on Amazon.com. The dispute shows one of the major problems that AI agents could face as they become more powerful.
An AI chatbot that simply answers questions is relatively easy for websites to deal with. An AI agent that visits websites, searches for products and attempts to buy things on behalf of users is different.
Companies need to decide whether they want AI agents accessing their websites and acting on behalf of customers. That could become an important issue as more AI companies build agents that can perform tasks online.
Privacy Is Another Big Question
There is also the question of how much information people are willing to give Muse.
For an AI assistant to be genuinely useful, it needs to know things about the person using it. Email, shopping accounts, calendars, messages and other personal information can make an assistant much more useful, but they also create privacy concerns.
Meta says users remain in control of what Muse can access. The company also provides controls that allow users to manage whether their data can be used to improve AI models.
Still, the more services someone connects to Muse, the more information the AI may be able to work with. This means users will need to pay attention to the permissions they give the assistant.
This issue could become even more important if Muse becomes deeply connected to Meta’s other products.
Meta Wants Muse Everywhere
The clearest message from Meta’s recent announcements is that Muse is not being treated as a small side project.
The company wants Muse to work across phones, computers, smart glasses and online services. It is also building partnerships that could allow the AI to interact with shopping, travel, work and communication platforms.
Meta CEO Mark Zuckerberg has described Muse as the centerpiece of the company’s vision for personal AI. He has said he expects the assistant to eventually become a personal superintelligence used by billions of people around the world.
That is an extremely large goal, but Meta has something that many AI companies would love to have, a massive existing audience.
What Muse’s Growth Means for ChatGPT and Other AI Apps
Muse is entering a market already dominated by major AI assistants such as ChatGPT, Gemini and Claude.
The difference is that Meta is not simply competing on the quality of answers. It is trying to make Muse useful across a person’s daily digital life.
The early download numbers are encouraging, but downloads alone do not prove that users will continue using the app. The bigger test will be whether people find Muse useful enough to make it part of their daily routines.
Meta will also need to deal with privacy concerns, security problems, mistakes made by AI agents and the question of whether other companies will allow Muse to interact with their services.
For now, however, Meta is clearly investing heavily in the product. The company is promoting Muse across its huge social media network while rapidly adding new features and partnerships.
What Happens Next?
Muse is still very new, so the product could change significantly over the coming months.
Meta has already announced plans for video conversations with Muse’s digital avatar, computer use on Mac, a dedicated email address, more service connections and integration with smart glasses. The company has also opened an early access program for users who want to try some of the new features before they become widely available.
The biggest question is whether Muse can move from being a popular new AI app to becoming something people actually depend on.
If Meta succeeds, Muse could become much more than another chatbot. It could become an AI assistant that sits quietly in the background, helping users shop, work, communicate, plan their days and complete tasks across the internet.
For a company with billions of users across Facebook, Instagram and WhatsApp, that is a very big opportunity. And judging by the amount of money, promotion and engineering effort Meta is putting behind Muse, the company appears determined to see how far this idea can go.
