Apple's iOS 27 Is Out and Siri Has Finally Had Its Glow-Up

After years of Siri being the punchline of every voice assistant conversation, Apple has pushed out iOS 27 and macOS Golden Gate 27, and the AI overhaul that comes with it is, by most early accounts, actually meaningful. The update has been rolling out since Monday, alongside tvOS 27 and watchOS 27, and it brings a substantially rebuilt Siri alongside a new visual design language Apple calls Liquid Glass.

The Siri changes are the headline here. Apple has spent the past two years rebuilding its assistant from the ground up, moving from what was effectively a glorified voice-activated search bar to something genuinely capable of multi-step reasoning. In iOS 27, Siri can maintain context across conversations, execute complex tasks that span multiple apps, and, critically, understand what is on your screen and act on it without you having to describe it.

What is actually new in iOS 27

The on-screen awareness feature is probably the most practically useful addition. If someone sends you a message asking to meet for coffee, Siri can now see that message, understand your calendar, suggest times, and draft a reply, all without you navigating between apps manually. It works with third-party apps too, not just Apple's own, which was a major limitation of earlier Apple Intelligence features.

The Liquid Glass design language is a visual update that Apple has been teasing since WWDC. It applies a translucent, depth-layered look to system interfaces, which looks genuinely striking on the iPhone Pro's display and somewhat less compelling on older screens with less colour accuracy. It is a cosmetic change, but it is the kind of cosmetic change that makes the OS feel noticeably different to use day to day.

Apple has also quietly added AI-powered video summarisation to Apple Home, though that one comes with a catch. The Apple Intelligence for Home feature requires an upgraded iCloud Plus subscription that costs up to 60 dollars per month at the top tier. For users who simply want smart summaries of their doorbell footage, this is a jarring price increase. Apple's approach of bundling AI features into subscription tiers rather than including them outright is becoming a pattern worth watching.

The Siri credibility problem

Here is the honest version of this story: Siri has promised significant improvements before and underdelivered. The Apple Intelligence launch in iOS 18 generated enormous coverage and ended up being mostly incremental. Developers and power users are approaching iOS 27's Siri claims with understandable scepticism.

That said, the early hands-on reports from journalists who tested pre-release builds suggest this update is more substantial. The multi-step task execution is genuinely faster and more reliable than what was available in iOS 26. The on-screen understanding works well enough to be useful rather than just impressive in a demo.

Apple's advantage over pure AI companies is the tight integration between hardware, operating system, and apps. When Siri can access the secure enclave on your device to run queries privately, when it has direct hooks into the camera, the sensors, and the app ecosystem, it can do things that a cloud-only assistant cannot replicate in the same way. The question is whether Apple is finally capitalising on that advantage properly.

macOS Golden Gate 27

On the Mac side, Golden Gate 27 brings most of the same Siri improvements alongside new writing tools that can generate and refine text in any app, not just Pages or Mail. There are also performance improvements for Apple Silicon Macs, particularly around on-device model inference, which means more AI features run locally rather than hitting Apple's servers.

For most iPhone users, this is a worthwhile update. The new Siri is genuinely more useful for everyday tasks than its predecessor, and the design refresh gives iOS a fresh feel after a few years of incremental polish. Whether it is enough to close the gap with what Google's Gemini or OpenAI's apps can do on the same hardware is a longer conversation, and probably one worth revisiting once people have had a few weeks to actually live with it.
