Meta’s new AI assistant, Muse, is quickly becoming one of the biggest new consumer AI apps in the U.S. The app has passed 5 million downloads in its first 22 days, according to estimates from mobile analytics firm Sensor Tower.

The milestone puts Muse among a small group of apps that have reached that level of adoption so quickly. Sensor Tower estimates that only 23 apps have surpassed 5 million U.S. downloads within their first 22 days, with most of those being major mobile games.

Muse Is Taking a Different Approach to AI

Meta launched Muse on Sept. 8 as a personal AI agent designed to do more than answer questions.

The app can browse the web and handle certain tasks for users, including working with email, shopping, filling out forms and making travel arrangements. That makes Muse part of a growing shift toward AI assistants that can actually complete tasks instead of simply generating responses.

The rapid adoption suggests that some consumers are interested in having an AI assistant that can take action on their behalf.

More Than 3 Million People Are Using Muse Weekly

The download number is only part of the story.

Internal data reported by The Information indicates that more than 3 million people prompt Muse each week, while more than 1 million people reportedly use the AI agent each day.

That level of activity could be important for Meta because downloads alone do not guarantee that people will continue using an app.

Muse appears to be attracting both curiosity and regular engagement during its first weeks on the market.

Muse Quickly Moved Up the App Charts

Muse also gained attention through Apple’s App Store and Google Play.

The app reached the top of the U.S. App Store shortly after its launch and later reached the top spot on Google Play. Meta has also promoted Muse heavily across its existing platforms, including Facebook and Instagram.

Sensor Tower reported that Meta increased its advertising spending for Muse in September, with downloads jumping 73% on Sept. 16. The company also used a large share of its own advertising inventory to promote the new AI app.

Muse Is Outpacing Several Major AI Apps

Muse’s early growth is particularly notable when compared with other popular AI assistants.

According to Sensor Tower estimates, Muse reached 5 million downloads faster than ChatGPT, Grok and Claude. ChatGPT took about 56 days to reach the milestone, while Grok took 103 days and Claude took 492 days.

The comparison gives Meta an early advantage in the race to make AI agents a mainstream consumer product.

Meta Sees Muse as More Than a Chatbot

Meta’s bigger goal is to make Muse part of everyday life.

Instead of asking an AI for information and then completing the work yourself, users can ask an agent to handle parts of the process. That could include finding better deals, managing subscriptions or helping with routine online tasks.

Meta CEO Mark Zuckerberg has also described a future in which the company could make money from transactions completed through Muse rather than relying entirely on traditional advertising.

The Next Challenge Is Keeping Users

The biggest test for Muse may now be retention.

Getting 5 million people to download an app is impressive, but Meta will need those users to keep opening Muse and trusting it with increasingly important tasks.

The company is also facing questions about how much personal information users are willing to give an AI agent. Muse’s ability to perform useful tasks can depend on access to services such as email and calendars, making privacy an important part of the consumer experience.

For now, however, Muse has made a remarkably fast entrance into the U.S. AI market.

With more than 5 million downloads and millions of weekly users only weeks after launch, Meta’s newest AI product is showing that personal AI agents may be moving from a tech industry experiment into a mainstream consumer category.

Meta Muse’s Rapid Start

Muse’s early numbers give Meta a strong starting point as it competes with established AI platforms.

Whether the app can maintain its momentum after the initial launch excitement fades will determine if the 5 million download milestone becomes the beginning of a lasting consumer AI success story.
