Good to know
Grammar Checker applies rule-based checks for common spelling, punctuation, capitalization and grammar issues, and shows the matched text for each. Spelling uses a built-in list of common English words, so uncommon, technical or proper-noun words may be flagged even when correct. Above about 12,000 characters live spell-check pauses, with a visible note, while the other checks keep running. Apply all rewrites the whole text, so review the result.
Frequently asked questions
Why is a correct word marked as misspelled?
Spelling uses a list of common English words, so rarer, technical or proper-noun words can be flagged; skip those suggestions when the word is right.
What does Apply all fixes do?
It applies every suggested fix at once and rewrites the text, so check the result, especially around any false positives.
Why did spell-check stop on long text?
Above about 12,000 characters live spell-check pauses to stay responsive, and a note tells you; shorten the text to check spelling again.
Are grammar suggestions always right?
No. They come from pattern rules, not full language understanding, so treat each as a suggestion and confirm it fits.
