ProWritingAid Grammar Checker & Writing Coach is more accurate than any other grammar/writing tool I have used. I run two grammar/writing tools on my desktop and ProWritingAid is consistently the tool that provides the best edits.

Only reason I managed to get an A in all my freshmen composition classes.
