Apple Unveils Rebuilt Siri AI as Centerpiece of Apple Intelligence at WWDC

Apple unveiled Siri AI, a rebuilt version of its voice assistant capable of holding conversations, understanding personal context, analyzing images, and completing more complex tasks across the company's devices, during its annual Worldwide Developers Conference (WWDC) on Monday. The announcement marks Apple's biggest update to Siri since the assistant launched in 2011 and follows a troubled rollout of Apple Intelligence, which forced Apple to delay key features, scale back its AI messaging at WWDC 2025, and defend itself against a class-action lawsuit over its marketing claims.

The new assistant is positioned as the centerpiece of Apple Intelligence, Apple's artificial intelligence platform spanning its ecosystem of devices and services. Apple said Siri AI can draw on a user's personal context, understand on-screen content, search messages, emails, photos, and files, and answer questions using information from the internet. Demonstrations showed the assistant drafting emails, editing and sharing photos, creating reminders, adding notes, and moving information between applications. Users can also ask follow-up questions and continue conversations in a chatbot-style interface, with Siri AI able to perform actions across apps through expanded system-wide integrations.

The rollout includes a dedicated Siri app that stores conversation history and synchronizes it across devices through iCloud, allowing users to begin a conversation on a Mac and continue it on an iPhone, iPad, Apple Watch, or Vision Pro. Apple said Siri AI runs on a new Apple Intelligence architecture combining on-device AI models with Private Cloud Compute, which handles more demanding requests on Apple-operated servers. Apple stated that data processed through Private Cloud Compute is not stored or accessible to the company and can be independently verified by outside security researchers.

The Siri announcement comes alongside a broader expansion of Apple Intelligence across Apple's other products, including Safari, which now uses AI to organize information. The rollout also reflects Apple's growing reliance on partnerships with outside AI developers, including integrations with OpenAI's ChatGPT and an agreement earlier this year to incorporate Google's Gemini into its AI offerings.

The event carried additional significance as Tim Cook delivered what he described as a final WWDC keynote as Apple's chief executive. "On a personal note, some of the greatest highlights of my time as CEO have been events like this, sharing powerful new tools with all of you, and then seeing what you create with them," Cook said. "It has been a constant reminder that imagination has no limits." John Ternus is set to take over as CEO on Sept. 1.
