David Pogue runs 125 tests on the new AI Siri in OS 27

Journalist David Pogue tested the new AI Siri shipped with OS 27 for iPhone, iPad, Apple Watch and Mac. Siri can search data across Mail, Messages, Notes, Files, Calendar, Contacts, Reminders, Photos and Music, all processed on-device. It failed only a handful of the 125 tests, mostly tasks tied to the Health app.

• Siri in OS 27 pulls answers from the user's emails, messages, notes and calendar
• All data stays on-device and is accessible only to the owner
• The assistant handles compound commands like adding a calendar event and sending an email
• Failures centered on the Health app, which is not yet integrated with Siri
