It's still fairly limited as to what it can do. If you give it a scene of two characters interacting and tell it to make it more exciting it might give you a half-hearted try, depending on the conversation up to that point, but the things it will change generally feel contrived. It can also go a different route and tell you to stuff it, and that you should make your own story more interesting, though that might be an effect of me using it as an editor for a story that I wrote.

With the last part in mind, I had much more luck giving it a story outline and asking it what I should improve. I honestly feel like this will instantly put many editors out of a job.
