Meta’s Muse AI App Surges Past 3.4 Million Downloads After Connect Push

Updated September 25, 2026 7:53 pm

Meta’s new AI app Muse has crossed 3.4 million downloads in less than three weeks, with the company’s developer-conference spotlight and heavy cross-promotion helping accelerate an already fast start. The app’s momentum matters because it shows Meta can still drive massive consumer adoption when it combines a polished product, broad distribution and aggressive marketing.

Fresh estimates from market intelligence firms suggest Muse’s early mobile performance is outpacing the launch trajectories of several rival AI apps, even if the exact download totals vary by tracker. The app, which launched on September 8 and is currently limited to users in the U.S. and Canada, is now sitting at or near the top of the app charts on both major mobile platforms.

What is driving Muse’s rapid rise?

Muse’s growth is being fueled by two forces at once: organic interest from early users impressed by the product, and a major promotional push from Meta across its own services and outside ad networks. The app’s rise accelerated after Meta Connect, where the company showcased new features and framed Muse as a more capable, more connected AI assistant for everyday use.

In the days after the conference, downloads climbed further and daily engagement improved, according to Sensor Tower’s estimates. The app’s momentum was already strong before the event, but Meta’s stage time appears to have given it another burst of visibility.

Industry trackers say the app’s performance reflects both genuine user demand and Meta’s ability to put its distribution machine to work behind a new consumer product.

How big is Muse’s early audience?

Muse has quickly become one of the fastest-growing AI mobile launches in recent memory, though the numbers differ depending on the measurement firm. Sensor Tower estimates the app has passed 3.4 million downloads. Apptopia places the total higher, at 4.3 million installs, while Appfigures reports about 2.3 million.

Those discrepancies are common in app-intelligence data, which often relies on different estimation methods and can lag behind live usage. Even with the variation, all three trackers point in the same direction: Muse is gaining users quickly.

Sensor Tower also said the app recorded a 27% jump in daily active users on Wednesday after Meta Connect wrapped up. That suggests the conference did not merely boost installs; it also helped pull more people back into the product.

Early download pace compared with other AI apps

Muse’s first two weeks were especially notable. Sensor Tower said the app reached an estimated 2.8 million downloads in that span and averaged 55% day-over-day growth between September 8 and September 17. By comparison, ChatGPT’s mobile app averaged 24% day-over-day download growth during its first 10 days. Claude and Grok, according to Sensor Tower, saw their download growth decline during their launches.

That comparison does not mean Muse has surpassed the long-term market impact of those products. But it does suggest Meta has managed to create a rare breakout moment in a crowded AI app market.

Why Meta Connect mattered

Meta Connect gave Muse a platform at exactly the right time. The company used the event to announce a series of features designed to make the app feel less like a simple chatbot and more like a broader AI layer across devices and services.

Among the planned additions are video chat with the Muse avatar, support for computer use on Mac, a dedicated email address, more partner integrations, and future compatibility with Meta’s smart glasses efforts. Together, those features point to a strategy aimed at making Muse more useful and more embedded in daily routines.

What Meta promised at the conference

The feature list matters because it signals where Meta wants Muse to go next. Rather than competing only on text generation, the company is trying to position the app as an assistant that can act across contexts and devices.

• Video chat with a Muse avatar
• Computer-use support on Mac
• A dedicated email address for the app
• Additional partner integrations and connectors
• Future smart glasses integration

That broader vision may help Meta differentiate Muse from other AI tools that still rely mainly on a chat interface.

How is Meta promoting Muse?

Meta is promoting Muse much the way it has pushed other apps across its ecosystem, but with a twist tailored to AI. The company is surfacing Muse to users of Facebook and Instagram, taking advantage of its massive installed base. It has also expanded marketing beyond its own platforms.

Sensor Tower says Meta started running house ads for Muse on September 9, just one day after launch. Within 10 days, Muse was getting the largest share of house-ad inventory across Meta’s properties, ahead of Facebook, Instagram and WhatsApp promotions. Meta has also begun advertising the app on mobile ad networks and on other social platforms, including Reddit, TikTok and YouTube.

Meta’s approach is different from the strategy it used with Threads, because AI promotions need to show a clear action or benefit rather than simply matching users to content they might like.

That distinction is important. Threads could be promoted through familiar social content patterns. Muse, by contrast, needs to communicate what the AI can actually do for a specific user in a way that feels immediate and useful.

How much of the growth is paid?

Not as much as some observers might assume. Sensor Tower said ads accounted for only 6% of Muse’s ad impressions from launch through September 19. That means the app’s surge has been driven mostly by organic adoption, word of mouth and platform momentum, not just paid media.

Still, Meta’s promotional firepower appears to be amplifying an existing trend rather than creating it from scratch.

Where is Muse ranking now?

Muse has been near the top of the U.S. app charts for days, reinforcing the sense that the app has crossed from niche launch to mainstream consumer attention. It reached No. 1 on the U.S. App Store on Friday, September 18, and has held that position since. It climbed to No. 1 on Google Play the next day, September 19, and remains there as well.

That dual-platform dominance matters because chart leadership often drives more discovery, which in turn can produce another round of installs. In the mobile world, visibility can become a self-reinforcing loop.

How does Muse compare with other recent launches?

Muse’s launch is notable not just for raw numbers, but for how quickly it reached scale relative to other well-known AI products. The app’s early pace looks especially strong when compared with the mobile launches of ChatGPT, Claude and Grok, based on Sensor Tower’s estimates.

There is a practical caution here: launch comparisons are useful, but they do not tell the full story. Products differ in audience, timing, platform availability and brand recognition. Even so, Muse’s growth suggests Meta may have found a formula that can translate its huge user base into direct AI app adoption.

What does this mean for Meta’s AI strategy?

Muse’s launch offers a glimpse into how Meta wants to compete in the next phase of consumer AI. The company is not only building a model or chatbot; it is trying to wrap AI in a product experience that benefits from Meta’s social reach, advertising network and hardware ambitions.

If Muse continues to expand, it could become a template for how Meta introduces future AI tools: debut with a flashy product, seed it through Facebook and Instagram, then extend it across devices, partners and eventually smart glasses.

The company is also learning a broader lesson that may matter as the AI market matures: distribution still counts. In a crowded category, a strong product may be necessary, but it is not sufficient. Meta’s advantage is that it can move attention quickly and at scale.

Why the launch is being watched closely

Muse matters because it is one of the clearest signs yet that Meta can create a consumer AI hit, not just a research showcase. The app’s early performance suggests the company may have found an audience willing to try an AI product when it is packaged well and introduced through familiar channels.

It also raises the bar for rivals. If Meta can sustain Muse’s momentum, other AI app makers will need to think more carefully about product design, app-store discoverability and how to turn curiosity into sustained use.

For now, the headline is simple: Muse is not just getting noticed — it is scaling fast, and Meta is putting its full weight behind keeping that growth going.
