Apple has released a comprehensive suite of operating system updates—iOS 27, macOS 27 (titled 'Golden Gate'), iPadOS 27, watchOS 27, and visionOS 27—each introducing a fundamentally reimagined Siri powered by generative artificial intelligence built on Google's Gemini technology. This redesigned assistant now integrates personal information from across a user's applications and processes on-screen context to deliver substantially more targeted and contextually aware responses.

The update marks the conclusion of a lengthy development period spanning more than two years from when Apple first previewed these capabilities, arriving as Siri competes with an expanding ecosystem of AI-driven productivity applications. Reviews indicate users are returning to Siri for meaningful daily tasks after years of limiting it to simple functions, whilst the broader OS updates deliver visual refinements and design consistency that extend across Apple's entire device ecosystem.
