What Makes ProWritingAid the Best Grammar Checker Online?
Editing software is like your regular spell check, but with superpowers.
Comparison to Published Writing
Using artificial intelligence, the software has analyzed millions of published books and articles and discovered a wealth of information. Those professional writers know what they are doing and it’s a great way to learn.
Grammar Structures
The software is able to break down most sentences into their various parts and recognize if you are using a problematic grammatical structure or word choice. For example, if you use a plural noun followed by the singular form of a verb, a prompt will pop up suggesting a change.
Document Analysis
These suggestions are based around your text on its own. Have you consistently used US English, or have you jumped between US and UK English? Have you used the same word multiple times within the same paragraph so that it sounds repetitive and strange?
Like Microsoft Word’s spell checker, the online grammar checker shows suggestions to help you make your writing more accurate, correcting your spelling mistakes and punctuation errors as you write.
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, so we highlight all potential issues in blue. 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?
ProWritingAid’s grammar corrector will catch errors as you write so you can make sure no grammatical mistakes slip through.
Punctuation Mistakes
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.
