Grammar Checker

The grammar checker reads your writing as you go and lists suggested fixes in the Inspector. It runs on your device using Apple Intelligence, so your text stays private, and nothing changes in your document until you apply a suggestion.

Note

The grammar checker is in beta. It supports most Latin-script languages that Apple Intelligence supports, though it isn't yet tuned for them the way it is for English, so results in other languages may vary. Support for Chinese and Japanese is coming.

What You Need

iOS, iPadOS, or macOS 26 or later
A device that supports Apple Intelligence, with Apple Intelligence turned on in Settings

If Apple Intelligence isn't available, the Inspector tells you why, such as the device not being eligible, Apple Intelligence being off, or the model still downloading. Misspelled words are still listed.

Start Checking

Open the Inspector on a text document and choose the Grammar Correction tab :atlas-grammar.checker:. The first time, tap Get Checking! on the introduction screen. Atlas remembers that choice across your devices through iCloud, so you only see the introduction once.

Atlas checks each paragraph a few seconds after you stop typing. Checking runs while the Grammar Correction tab is open and pauses when you leave it or when Atlas is in the background. The Corrections header shows a progress bar and a status of Waiting, Checking, or Up to date.

Tip

On iPhone, the Inspector opens as a short sheet when you choose the Grammar Correction tab, so you can keep writing above it. Drag the sheet up for a larger view.

Reading Corrections

Issues are underlined in purple in the editor, and each one gets a card in the Inspector. Select a card to jump to the issue in your text.

Underline	Tag	What it means
Solid	Suggested	The checker is confident about the mistake and its fix.
Dashed	Consider	The checker found a likely mistake, or the fix needs a second look before you apply it.

Each card also shows a category, such as Agreement, Tense, Punctuation, or Word order, followed by the original text, the replacement, and a short explanation.

Applying or Ignoring a Correction

Apply replaces the text with the suggestion. You can undo it like any other edit.
Ignore hides the correction until the paragraph changes.

Tip

Review Consider corrections before applying them. The checker flags them because the fix may not match what you meant.

Spelling

Misspelled words appear in the same list, in the order they occur in your text. Spelling uses your system dictionaries and follows your device's languages, so it works even without Apple Intelligence. Spelling cards offer:

Select to choose from suggested spellings
Learn to add the word to your dictionary
Ignore to stop marking the word in this document

Misspellings appear when Check Spelling While Typing is on.

Other Languages

If a paragraph is in a language the checker can't handle yet, a note under the list tells you how many paragraphs weren't checked and which language they were in.
