Apple's long-awaited AI-powered Siri overhaul, featuring on-device processing and private cloud compute, was detailed at Monday's WWDC keynote.

Apple used its annual Worldwide Developers Conference keynote on Monday to reveal extensive details about a revamped, AI-powered Siri, the culmination of a development effort that has unfolded against the backdrop of a $250 million lawsuit. [1]

The updated assistant is built around what Apple calls “personal context” — information stored in native apps including iMessage, Notes, Calendar, Mail, and Photos — and is also designed to be aware of what is currently displayed on a user’s screen. [1]

In one demonstration at WWDC, Justin Titi, an Apple Senior Director working on AI engineering, asked Siri to recall a dessert his daughter had mentioned. [1] The assistant searched across his device and surfaced a text message from approximately a month prior in which his daughter said she wanted to make coconut cookies. [1]

The revamped Siri will be available on iPhones, laptops, and the Apple Vision Pro mixed reality headset. [1] Unlike Google’s AI search integration, the new Siri can be toggled on and off by users who prefer not to use it. [1]

On the privacy front, Apple is relying on two distinct approaches depending on task complexity. [1] Simpler features — such as email summaries and AI-generated emoji — are processed entirely on-device, which Apple says is both more secure and less energy-intensive than cloud computing. [1] For more demanding tasks, Apple has developed what it calls private cloud compute (PCC), a system designed to process complex data in the cloud without exposing that data to Apple itself. [1] Apple offers a $1 million bug bounty to anyone who can demonstrate a successful breach of PCC; no such breach has been publicly reported. [1]

The question of whether Siri will be able to integrate with non-native, third-party apps remains open, with Apple suggesting that integration may depend on individual developers. [1] Third-party mobile AI assistant apps such as Poppy and Poke already attempt to offer similar agentic functionality, though they require users to share significant personal data to operate effectively.
