NSFWriting review
NSFWriting separates scene writing, book projects and character cards. I’d use the scene tool for an idea that only needed a beginning and an end. If I expected to come back for several chapters, I’d start by writing down who the characters are and what they each want.
Give the scene enough information to move forward
The public writing help suggests keeping character traits distinct and giving a continuation a short piece of context. I’d try that with two character notes and one event that has to happen next. NovelAI is worth comparing if you want recurring details to come from keyword-triggered lore in the story editor.
Keep reusable character notes separate
The homepage lists separate tools for books and character cards. I’d keep a compact version of the cast notes there or in my own file, then put the immediate scene details in the prompt. The writing guide treats a continuation differently from a first scene, so I’d edit the recap when I moved on to a new chapter.
Anabel’s take
I’d start with a single scene to see how the tool handles a small cast. If I wanted to continue it, I’d save the character details before changing the prompt for the next chapter.
