Useful takeaways from this story.

Siri has been completely rewritten and is the headline feature, combining advanced AI with access to personal on‑device data for more natural, context-aware interactions.

iOS 27 is available to devices that ran iOS 26 (as far back as iPhone 11), but advanced Siri features require iPhone 15 Pro or later, English language setting, and an enrollment process.

Access to Siri AI involves updating to the latest software, waiting for a device-side data‑gathering process, and joining a waitlist before the feature becomes available.

# What iOS 27 is and why it matters

Apple's iOS 27 is a major update across the company's platforms — iPhone, Mac, watchOS and tvOS — with one clearly emphasized change: a rebuilt Siri. Apple rebuilt the voice assistant to provide more capable, conversational, and context-aware interactions by combining new AI capabilities with access to personal information stored on the device.

# The new Siri: how it works and what it can do

A few details about availability and limits:

  • The fully featured "Siri AI" is exclusive to iPhone 15 Pro and later.
  • It requires English as the device language.
  • Users must update to the latest software, allow a device-side data‑gathering process to run, and join a waitlist to gain access. Some preparation may have been handled by earlier updates.

# Device support and performance

Apple has made iOS 27 available to all devices that previously ran iOS 26, reaching back to the iPhone 11 and including compatible iPhone SE models. The release places emphasis on performance improvements that can make older hardware feel faster and more responsive. While some headline features are limited to newer phones, many enhancements and refinements apply broadly across supported devices.

# Safety and app refinements

iOS 27 adds new child‑safety protections and refinements across many built-in apps. The update also brings subtle usability improvements and strengthened protections for families. These changes are positioned as part of the wider platform refinements accompanying Siri and system performance work.

# How to get the new features

  1. Update your iPhone to the latest iOS 27 release.
  1. Join the Siri AI waitlist when prompted in Settings.

If your device isn't eligible for Siri AI, you still receive the broader iOS 27 improvements: performance upgrades, app refinements, and new safety features.

# What this signals for Apple's platform direction

# Bottom line

Install iOS 27 for general performance, app refinements and safety updates. If you have an iPhone 15 Pro or later and use English, follow Apple's setup flow to enroll in the Siri AI waitlist and complete the device data process to unlock the most advanced assistant features.
