Apple is rolling out an upgraded AI writing toolkit in iOS 27, adding a Siri‑powered "Write With Siri" toggle to the keyboard and a "Help Me Write" prompt that surfaces while typing. The update promises deeper text generation, rewriting, and a new grammar checker that mirrors Grammarly’s style.

The new grammar assistant appears as a translucent panel in Messages, Mail, and other apps, listing suggested edits beside the original text. Users can accept, reject, batch‑approve, or ignore changes, pause the checker, and navigate flagged sections. This feature builds on Apple’s existing spell‑check, delivering a more comprehensive writing aid.

Introduced at the June 8 WWDC keynote, the enhanced Writing Tools signal Apple’s broader push for iOS 27 AI capabilities, including updates to Photos and the Camera app. The rollout positions iPhones as more capable writing platforms, offering consumers a built‑in alternative to third‑party editors.
