At WWDC 2026, Apple announced the most significant upgrade to its ecosystem in years: a completely rebuilt Siri powered by Apple Intelligence. Moving beyond simple voice commands, the new Siri is capable of understanding personal context and executing complex actions across multiple applications.

Key features include on-device semantic indexing, which allows Siri to understand what is on your screen and in your apps without compromising privacy. For example, you can tell Siri to 'send the photo I took yesterday to Rohit' and it will search your gallery, identify the photo, open WhatsApp or iMessage, and send it instantly.

Apple's focus on private cloud compute (PCC) ensures that heavy LLM computations are processed in secure, specialized server environments where user data is never stored. This marks a new milestone in localized, privacy-first AI deployment that is set to change how we interact with mobile devices.
