One of the best use cases for AI in writing fiction is as an expert personal research assistant. A common writing tip is to “write what you know.” This doesn’t mean to only write about your personal life, but to write about things you personally know about. That could mean doing research about certain topics you haven’t experienced personally until you are familiar enough to convincingly write about that topic. The problem with research is that it can take a lot of time, which limits the amount of actual creative writing you can do. That’s where AI comes in.
