Muse also crossed 5 million downloads in 22 days, faster than ChatGPT (56 days), Grok (103 days), or Claude (492 days), per Sensor Tower estimates, helped heavily by Meta's own ad spending push that gave Muse up to half of Meta's daily house ad impressions. Separately, the BBC tested Muse and found it requests broad access to Gmail, calendar, and even full computer control on Mac, with Meta training its AI models on user data by default (opt-out available). A security researcher also found and reported a critical flaw that Meta quickly patched, and Amazon has blocked Muse from shopping on its site. ## Full article daily.dev links to this article rather than hosting it.

Muse passed 5 million downloads in 22 days after its US launch, according to a Sensor Tower projection. By comparison, ChatGPT took 56 days to reach 5 million downloads, Grok took 103 days, and Claude took 492 days. Meta's own aggressive ad spending, which took up to half of its daily house ad impressions between mid and late September, contributed to the fast growth. _Developers evaluating AI agent platforms can follow adoption trends like this one on daily.dev._ ### What permissions does Meta's Muse AI assistant request from users? Muse asks for control of a user's Gmail and calendar, and on a Mac it requests control of the entire computer, based on BBC testing. Meta also uses Muse interaction data to train its AI models by default, saying it strips personal details first, though users can opt out in settings. _Anyone weighing AI assistant permissions against privacy risk can track reporting like this on daily.dev._ ### Was a security vulnerability found in Meta's Muse app after launch? Yes, security researcher Patrick Wardle, co-founder of Objective-See, found a critical flaw in Muse shortly after its launch, which Meta fixed immediately. Meta stated it had delayed the app's release for months to conduct extra privacy and security testing before shipping. _Security-conscious developers tracking new AI app vulnerabilities can follow updates like this on daily.dev._ ## Similar posts on daily.dev - [Meta debuts its Muse AI agent.
