Muse by MetaSamuel Boivin | Nurfoto | Getty ImagesMeta on Tuesday unveiled its personal agent app called Muse, which it said can perform tasks like booking appointments and filling out forms. Users can access the app through a free tier or with a monthly subscription plan, which ranges in price from $20 to $100. Alexandr Wang, head of artificial intelligence at Meta, told CNBC that the app runs within “its own sandbox” and “never sees” details like passwords or payment information. Wang also said that Muse “feels very accessible, friendly and explainable.” As CNBC’s Jonathan Vanian notes, the product comes as Meta faces a broader public reckoning, with legal implications, stemming from its privacy and security policies. At the same time, Meta is also under pressure from Wall Street to prove that it can generate returns from its huge investments in AI.5.

A CNBC analysis found that the president’s nine top positions in the sector increased between $1.5 million and $4.4 million between the eve of the conflict and the end of August. As CNBC’s Luke Fountain reports, Trump’s accounts have continued to trade energy stocks like ExxonMobil and Chevron throughout the conflict. Some transactions were made on days when Trump’s announcements caused notable swings in energy markets. CNBC found no evidence that Trump directed the transactions or that his investment managers had advance knowledge of the president’s decisions. The Trump Organization has said that Trump’s asset managers use automated trading. The White House said independent managers oversee its portfolio.
