What is Muse?
Meta aims to let users delegate daily tasks to Muse, the AI agent it launched on September 8. The app runs on a dedicated cloud-based computer and uses its own browser to fill out forms, shop or organize a trip.
Download numbers
According to Sensor Tower estimates, Muse passed 5 million downloads in the US in 22 days. By the same data, ChatGPT's mobile app reached that level in 56 days, Grok in 103 days and Claude in 492 days. Muse stayed at the top of the US App Store free apps chart for 12 days.
However, the launch conditions were not identical. Muse is available on both iOS and Android in the US and Canada, while Grok and Claude were iOS-only during their first five days.
How it works
Muse keeps running long tasks even after the user closes the app, and returns to the user when something happens or approval is needed. For example, it can turn a recipe saved on Instagram into a shopping list, or prepare a plan for a goal the user shares and follow up on the tasks that plan requires. Users can interact with Muse through the app or by messaging it on WhatsApp.
Meta says user approval is obtained before actions such as sending emails or making purchases, and that access to connected services is determined by the user.
Ad support and revenue model
Strong promotional support is also behind the download surge. According to Sensor Tower, Meta increased ad spending for Muse on September 16, and the app's daily downloads rose 73 percent compared with the previous day. Between September 14 and 27, Muse's share of daily impressions for ads promoting Meta's own products reached 50 percent on some days. The app also entered the top 15 brands in the US by ad impressions in the week of September 21-27.
Meta's revenue model for Muse is built on subscriptions and transactions carried out on the user's behalf. Alongside free usage, there is a $20 monthly tier offering higher usage limits for background tasks and automations; for heavier agent use, the price rises to $100 a month. The company also plans to take a commission on purchases and reservations made through Muse.
The real test
Five million downloads do not reveal how many people use Muse regularly or how many users have moved to a paid subscription. Understanding whether the early interest turns into a lasting habit will require active usage, return rates and subscription data.
