​I’ve used the free version of Grammarly for years, but I didn't upgrade to Grammarly Premium until recently. In short, the premium version is completely worth it—if you plan to use Grammarly regularly. Which means for me, it’s invaluable. Is it always correct? No. But the editing tool is my “second opinion” for polished material. And here’s why.

Proofreading is the act of reviewing the final draft for mistakes (also called copy editing). Plain and simple. This means if you’ve been asked to proofread material for work or for a friend, the content you’re reviewing has already been thoroughly edited. All you need to search for are misspelled words, missing punctuation, and formatting inconsistencies (indents, margins, etc.). 

So, what if your boss asks you, “Can you proofread this newsletter before it’s sent out?” What does he mean? Or what should he mean? In most cases, everyone’s definition of proofreading is similar, but there are varying opinions out there. Rest assured, proofreading is less involved than true editing. Usually, whatever you’re proofreading is the last and final draft.
