Meta launched Muse, a personal AI agent app that performs tasks like filling forms and managing emails, and it's already topped the iOS app store charts ahead of ChatGPT. The rapid adoption has boosted Meta's stock 11%, but Amazon blocked the app over privacy concerns while Shopify partnered with it.

• Muse reached 2.5 million downloads in 13 days, surpassing Claude (400K) and Grok (200K), though ChatGPT still pulled 3.1 million in the same window
• Meta is monetizing the free app through $20 and $100 monthly subscriptions, diversifying revenue beyond its core advertising business
• Amazon blocked Muse from its platform citing privacy and security risks—the app captures credentials and scrapes account data without advance notice—while Shopify chose to partner with it instead
