Think about how long grammar-checking software has existed. Microsoft Word had it in the 1990s. Grammarly built an entire company around it.
And yet, all this time, your iPhone has been catching typos while completely ignoring whether your sentences actually made sense. That gap is finally closing.
iOS 27 will introduce a dedicated grammar-checking feature to Apple Intelligence’s Writing Tools.

When you’re composing a message or email, a translucent panel slides up from the bottom of the screen showing your original text alongside suggested revisions.
You can approve each fix individually, accept everything at once, or skip the whole thing. It’s the kind of workflow Grammarly users will recognize immediately.
The grammar tool is just one piece of a broader Writing Tools overhaul. Apple is also adding a “Write With Siri” toggle directly above the keyboard, as well as a “Help Me Write” prompt that appears whenever Siri is activated in a text field.
So rather than hunting through menus, the AI writing assistance surfaces right where you’re already typing.
The expanded Writing Tools will also handle more substantial text generation and rewriting than the current version allows, though Apple is keeping specifics close to its chest ahead of the WWDC keynote on June 8.
The full picture gets unveiled at Apple’s annual developer conference, where iOS 27 takes center stage alongside a rebuilt Siri with significantly expanded conversational abilities.

Writing Tools are just one corner of a much wider Apple Intelligence push that also extends into Photos and Camera.
Apple spent years building a spell checker and drawing a hard line right there. Crossing into grammar territory meant entering messier, more subjective linguistic territory, the kind of space where suggestions can feel presumptuous rather than helpful.
The fact that Apple is now doing this, complete with a review interface that lets you approve or reject changes one at a time, suggests they’ve spent real time thinking about how to make AI suggestions feel like assistance rather than correction.
