Apple has unveiled Siri AI at WWDC26, describing it as an entirely rebuilt version of its assistant that is more conversational, more capable and more personal. Powered by the next generation of Apple Intelligence, the new Siri adds personal context understanding, broad world knowledge and onscreen awareness, marking one of the company's most significant assistant updates in years.
A ground-up rebuild
Apple says Siri has been rebuilt from the ground up with AI at its core, taking advantage of a new architecture for Apple Intelligence. That architecture includes the next generation of Apple Foundation Models, which run both on device and on servers using Private Cloud Compute, the company's privacy-focused server approach.
What the new Siri can do
Apple highlighted several capabilities for the revamped assistant:
- Personal context: surfacing relevant information from a user's messages, emails and photos.
- World knowledge: answering questions from the web across a wide range of topics.
- Onscreen awareness: understanding what is on screen and interacting with apps accordingly.
Privacy and architecture
Apple emphasized that processing relies on on-device computation where possible, with Private Cloud Compute handling more demanding tasks. This design is central to the company's positioning of AI features as both capable and privacy-preserving, a contrast it frequently draws with cloud-dependent assistants.
Availability and rollout
The rollout is phased rather than immediate:
- New Siri AI features became available for developer testing at announcement.
- A user beta is expected later in the year.
- Initial availability targets US customers in English, with other languages to follow.
Apple noted the features would not be immediately available in the European Union or China due to regulatory considerations in those markets.
Why it matters
The update arrives after a long period of anticipation around Apple's assistant strategy. By integrating personal context and onscreen awareness while leaning on on-device processing, Apple is attempting to differentiate Siri on privacy while closing the capability gap with rival assistants.
The practical impact will become clearer as the beta reaches users and developers build on the new Apple Intelligence architecture. For now, the announcement signals Apple's intent to make Siri a more central, systemwide part of its devices, powered by models that span the device and Apple's own cloud.
Competing on privacy
Apple's approach to AI continues to lean heavily on its privacy positioning. By performing as much processing as possible directly on the device and routing more demanding tasks through Private Cloud Compute, the company aims to deliver capable assistant features without sending large amounts of personal data to external servers. This design is meant to differentiate Siri from cloud-first assistants while addressing user concerns about how personal information is handled.
The phased rollout, with developer testing first and a broader user beta later, reflects the complexity of rebuilding a deeply integrated assistant. The decision to delay availability in certain markets such as the European Union and China highlights how regulatory considerations shape where and when AI features can ship. As the new Siri reaches more users, attention will focus on how well its personal context and onscreen awareness work in everyday use, and whether the privacy-centric architecture can keep pace with rival assistants on raw capability.
