A writer with a voice, not a template
Choose one of three writer personas before the first word, or none at all. Spicy is fast and direct, Pyra builds slowly with close detail and long pining, Onyx writes dark and controlled, and No Writer leaves the voice to you. The same idea reads very differently in each, so pick the one that sounds like the fics you like to read. Each also takes direction mid-fic, such as shorter scenes or more banter.
Continuity is the hard part, so it is handled
Fanfic falls apart when chapter nine forgets chapter two. The writer keeps track of who knows what, who is hurt, which promises the plot has made and which jokes keep coming back. You stay in charge: ask for a scene again, change the heat, or steer the next chapter with a line of direction. Everything starts here with your idea and a few quick questions, and the chapters are written in the full editor on a free account.
