Apple unveiled iOS 27 with a redesigned Siri that can sustain conversations, compose emails, search photos and messages, and handle sophisticated requests. The update brings Siri closer to ChatGPT and Claude, but AI agents such as Instinct and Meta’s Muse are moving beyond dialogue by completing tasks online, including travel arrangements, registrations and calendar management. Instinct, built by an 11-member startup, has reached a $2.5 billion valuation and operates through Gmail, iMessage and WhatsApp. Muse recorded nearly 600,000 downloads in its first five days, according to SensorTower. Apple shares rose 0.63% after Monday’s launch. Apple’s privacy-focused approach limits access to user data and third-party services, potentially constraining AI performance, while platforms such as Instinct and Muse raise security concerns because they require access to personal information. Former Apple AI team members told the Wall Street Journal that the company’s privacy principles may slow innovation. The competitive pressure could test whether Apple’s integrated ecosystem can justify premium pricing if external AI agents offer more capable assistance.
