Automated spellcheckers and grammar checkers, such as those built in to your word processing software, are better than they used to be. But they can still take a difficult situation and make it worse.

You have to know which options to set on or off, which rules you can ignore and which you can’t. They often highlight something as an error when it isn’t. They are also blind to certain types of mistakes, which they fail to spot. And when they do alert you to a genuine error, they often don’t tell you how to fix it.

So while these software tools can be helpful, you still need a human being with the skills to spot mistakes and the knowledge of how to fix them.

Maybe you lack these abilities yourself, or maybe you want a second opinion or simply have better things to do with your time.

That’s where a professional proofreading service can help you.
