Apple Intelligence Writing Tools help users rewrite, proofread, and summarize text anywhere on their iPhone, iPad, or Mac. Introduced in October 2024 with iOS 18.1, the tools act like a built-in editor that can adjust the tone, length, or style of whatever a user is typing.
Details
Writing Tools are part of the Apple Intelligence suite, powered by on-device and cloud-based foundation models (language models trained to perform multiple tasks). They appear as a system-wide overlay in any text field and offer actions like Rewrite, Proofread, Summarize, and — added with iOS 18.2 — a Compose option powered by ChatGPT that can generate text from scratch. Apple processes requests using its Private Cloud Compute system, which Apple states is designed to keep user data private and not stored by Apple. The tools work across Apple's own apps and in third-party applications that support the standard text editing APIs.

OtherSafari's Intelligent Tracking Prevention (ITP) uses machine learning running directly in the browser to identify advertising networks and data companies that track users across different websites, and then blocks or limits their ability to do so. First introduced in September 2017, ITP has been updated continuously and now blocks third-party tracking cookies entirely by default.Creative GenPersonal Voice is an accessibility feature introduced with iOS 17 in September 2023 that lets users create a synthetic voice that sounds like their own. It is designed primarily for people who are at risk of losing their ability to speak due to conditions like ALS. After recording 150 short phrases (roughly 15 minutes of audio), the device processes the recordings overnight using on-device machine learning and creates a voice clone the user can speak through in calls, FaceTime, and apps.OtherApple Watch uses machine learning algorithms to detect when a wearer has had a hard fall or been in a car crash, and can automatically contact emergency services if the person is unresponsive. Fall Detection has been available since Apple Watch Series 4 in 2018. Crash Detection for severe car accidents was added with the iPhone 14 and Apple Watch Series 8 in 2022.
