Another writer friend recently recommended Grammarly to me. I've never used it before, but from my understanding it's a service that detects a whole host of grammatical issues within your work. I'm generally decent with grammar, but I have a big-time issue with passive voice. I understand what it is, and I'm just fine at seeing it in other people's work, but when it comes to my own writing I have difficulty finding it. And not because it isn't there- it IS, but because I know what I mean to say, I don't realize that I'm saying it "incorrectly".
So, is Grammarly worth the cost? What experiences, both positive and negative, have people had with this serivce? Are there any lower or no cost services that could do the same thing?
Thanks everybody!
