What kinds of mistakes can our grammar checker highlight?
English grammar isn’t easy, but the grammar check report will help you zero in on key embarrassing mistakes.
Spelling Errors
Spelling mistakes are highlighted red in your text when using our grammar checker. If you click the word, you’ll be shown a list of suggested corrections.
Commonly Confused and Misspelled Words
Our best grammar checker has also been programmed with a list of the most commonly confused words in the English language and will use the structure of the sentence to help you figure out when you have the wrong usage.
Grammar Errors
Grammar can be a bit of a minefield. Perfect grammar is hard and there are so many ways to slip up.
Do you have subject—verb agreement? Did you write "it’s" when you really meant "its"? Have you accidentally written a sentence fragment?

How many times have you been tripped up by comma splices? Or semi-colons? Or apostrophes? A good punctuation corrector will help you learn the ins and outs of punctuation rules.
ProWritingAid’s suggested changes will always be accompanied by an explanation to help you understand the rules so that you don’t make the same mistake next time.
