Meta Platforms' new personal AI agent Muse has emerged as a consumer hit, but Surfshark's analysis found it disclosed potential collection of 31 of Apple's 35 data types, compared with an average of 13 across the major AI apps studied. Only Meta AI ranked higher, while Gemini disclosed 24 types and ChatGPT 17. Apple's privacy disclosure says Muse may collect linked user data including precise location, financial and health information, contacts, emails and browsing history. It also lists precise location, financial information, browsing history and device identifiers as data that may be used for third-party advertising. Meta says Muse interactions may help train its AI models, although users can opt out, and says Muse conversations and data stored in its virtual machine are not shared with its advertising systems. The agent can connect to email, calendars and other services to book travel, shop and send messages, giving it access to detailed information about users' routines and preferences. Muse topped U.S. app charts and reached roughly 2.5 million U.S. downloads within two weeks of launch. Meta shares gained 12.9% over the previous five trading sessions before falling almost 4% Monday afternoon amid a broader technology-stock selloff. Analysts cited in the source see personalized AI products gaining momentum, while Polymarket traders assign Meta about a 2% chance of having the top-ranked AI model at the end of 2026, based on a market with more than $1 million traded.
