Apple introduced Siri AI at its annual Worldwide Developers Conference on Monday, unveiling a completely rebuilt version of its voice assistant. The new Siri can hold natural conversations, understand personal context, analyze images, and complete complex tasks across Apple devices.
This is Apple's biggest update to Siri since it launched in 2011, and comes after a troubled rollout of Apple Intelligence. The company faced delays, scaled back its AI messaging last year, and defended against a class-action lawsuit over marketing claims. The setbacks raised questions about whether Apple was losing ground to OpenAI, Google, and Anthropic.
The announcement also marks Tim Cook's final WWDC keynote as CEO before John Ternus takes over on September 1.
Cook said, "It has been a constant reminder that imagination has no limits."
Siri AI is the centerpiece of Apple Intelligence. It can draw on a user's personal context, understand on-screen content, search messages, emails, photos, and files. During demonstrations, Apple showed the assistant drafting emails, editing photos, creating reminders, and moving information between applications. A dedicated Siri app stores conversation history and syncs across devices via iCloud.
Apple said Siri AI runs on a new architecture combining on-device AI with Private Cloud Compute. Data processed through that system is not stored or accessible to Apple, and can be verified by outside security researchers.
The rollout also includes a major expansion of Apple Intelligence across Safari, Messages, Mail, Calendar, Photos, Home, and Shortcuts. Safari now uses AI to organize tabs and monitor webpages for price drops. Photos gets new editing tools and a redesigned Image Playground for photorealistic images. Those images will include SynthID watermarks.
Siri AI is available for developer testing now. It launches in beta later this year in English, but will not be available at launch on iPhone and iPad in the European Union. It will remain unavailable in China due to regulatory requirements.
Closing his final WWDC keynote, Cook said, "I truly believe the best is still ahead at Apple."
