Apple announced Siri AI at WWDC 2026, a completely redesigned AI assistant powered by the next generation of Apple Intelligence. Key features include personal context understanding (searching across messages, emails, photos, and notes), onscreen awareness, web-powered intelligence for real-time information retrieval, and more natural multi-turn conversations. A standalone Siri AI app is launching for the first time, with cross-device sync via iCloud. The assistant integrates deeply across iPhone, iPad, Mac, Apple Watch, Vision Pro, CarPlay, and AirPods. Privacy is emphasized as a core principle, with on-device processing and Private Cloud Compute for sensitive requests. Developer access is available now, with a public beta coming later this year.
