No! Scrivener flexes to work for your process, whatever that is. I’m not a plotter (at all), and I can’t imagine writing without it. Scrivener helps me visualize the structure of my story as it grows, find exactly the scene I want to work on, easily move things around, store old words, keep track of ideas for future scenes or snippets of scenes, and so much more. Of course, it’s also great for plotters, who can use the Corkboard to build a storyboard, or lay out the structure of their book in advance.
