If you have a document, be it a paper for class, business proposal, novel up for publishing, or anything in between, I'll go over it to make sure everything is exactly the way you want it.
If you're aiming for a certain tone, I can make sure it matches.
If you're missing key points, I will show you where.
If you're putting too much emphasis here or too little there, I'll even it out.
And then, of course, grammar, spelling, and punctuation.
