Hey Violet,
When I said "applications", I was referring to software applications, like Final Draft, which is a brilliantly developed application that I recently acquired for use on my screenplays. I should emphasize that a software application is intended to make the job of screenwriting easier by making sure that one doesn't make structure mistakes, but it isn't going to think of ideas for me. I don't want that, and I don't need that. Final Draft simply allows me to focus more on the fluidity of my ideas within the writing, while it focuses on the structure and uniformity of it as I go, because when one's imagination is unraveling, they don't have time to stop and think about structure.
Other apps, like Moviemagic screenwriting software has a good reputation too. Essentially, all of these apps act like super advanced plug-ins for Microsoft word, making sure that your work remains properly formatted for screen, stage, television, etc. So I wouldn't call a user of these applications "cheaters", but if you still insist, then you'll be calling a hell of a lot of people in the entertainment industry cheaters.
As for your departing question on the legitimacy of technically labeling oneself a "screenwriter", I have to say, that if you've already, are currently, or are going to write and/or type something for artistic translation to a visual medium of some sort, then you can consider yourself a screenwriter. Although, I ‘m sure that you’ll get a much more philosophically pleasing answer to that question from someone like Robert McKee or Syd Field.
I Hope that alleviates your concerns…
