“This is IT. That is my voice.”
I gotta say, the editor is *** fantastic, bro. The things it catches and the things it flags are *** incredible.
My workflow has just about tripled since I've been using it and I couldn't be more pleased!
It’s literally like having a true editor with a critical eye and a great creative brainstorming partner all wrapped up in one.
The developer has been super helpful and is clearly very passionate about the app, constantly providing updates. A great tool.
I'm blown away by the nuance that I'm seeing with the writing analyzer.
