The idea of Grammar Check must have been invented by computer programmers who thought grammar is like math. The problem is, it isn’t. Many words can function as different parts of speech. In math, a two is a two; in grammar, lead can be a noun (the chemical element) or a verb (the act of guiding someone on his way). You have to read the word in context to identify how it functions in a particular sentence.
That is why Grammar Check can often suggest something that may not be appropriate. It can handle the sentence “See spot run,” but for any sentence more complicated than that, Grammar Check simply cannot be trusted. In fact, it’s so bad that most editors recommend you don’t use it at all, because it could make you think a correct sentence is incorrect. It’s not second best; it’s worse than not copyediting at all.

Let me give you an example. In the two sentences below, Grammar Check found two supposed mistakes. The problem is there is nothing wrong with either of the sentences.
Either make any additional changes to the text as you see fit or simply disregard the comment.
Grammar Check advises: “Either makes any additional changes …”
Before proceeding please be sure you have saved your manuscript to the hard drive of the computer.
Grammar Check advises: “Before proceeding please is sure you saved the manuscript …”
As you can see, without human intervention, Grammar Check would make the sentence incorrect or not make sense. That is why you want to use a human being and not a machine to make your manuscript as good as it can be.
