Meta's Muse AI personal agent tool became the number one free app on Apple's iOS store in the U.S. on Monday, surpassing OpenAI's ChatGPT, Polymarket, Kashi, Anthropic's Claude, and SpaceXAI's Grok, according to CNBC. [^1]

The rank puts Meta's consumer agent above the named rivals on the day's chart, though the facts do not say whether the order holds or what drove downloads.

Separately, a Business Insider report filed the same day says Muse AI lets users opt out of having their chat data used to train Meta's AI models. The option sits in the Data Controls section of Settings, under a toggle labeled 'Help improve our AI models.' [^2]

What the record does not say is how many users have flipped that toggle, or whether the No. 1 rank will hold past Monday's reading.
