Apple just gave Siri the biggest glow-up in its 15-year existence. At WWDC 2026 on June 8, the company rebranded its digital assistant as “Siri AI,” layering on conversational intelligence, personal context awareness, and a dedicated app for managing conversation history.

But the product news wasn’t the only headline. The keynote also served as Tim Cook’s final appearance as CEO before he transitions to executive chairman on September 1, 2026. After 15 years running the world’s most valuable company, Cook is handing the reins to John Ternus, currently Apple’s senior vice president of hardware engineering.

What Siri AI actually does differently

The rebrand isn’t just cosmetic. Siri AI is built on Apple Intelligence, the company’s on-device AI framework, and introduces meaningfully improved conversational abilities.

On-screen awareness is a key new feature. Siri AI can now read and react to what’s currently displayed on your device, pulling context from apps, messages, and documents to deliver more relevant responses.
