The Two Presence Maps
The Presence tab under Characters holds two maps of the same cast, and the difference between them is the point. The first one is yours: the chapters holding a scene you tagged a character into, filled in from the Characters chip in a scene's details. It costs nothing, needs no analysis, and is there with AI switched off entirely — so a writer who never runs a single analysis still gets a real map of where they placed each character.
The second is the analysis's read of the same question: how often each character's name comes up, chapter by chapter. That is mention density rather than proof of presence — a character a chapter talks about counts the same as one who is in the room. It is the wider net, and it catches the appearances you would never think to tag: talk about someone offstage, a reputation arriving ahead of them, influence on a decision made without them.
Read them against each other and the gaps mean different things. A character missing from your own map may be a gap in the record rather than in the story — tag the scene and the row fills. A character missing from the analysis's map is missing from the prose.
The most valuable information in either map is negative space. Read across a row and look for long gaps where a character is absent from multiple consecutive chapters. If your secondary protagonist disappears for five chapters in the middle of the book, readers may forget about them or lose investment in their storyline. If an antagonist is absent for too long before the climax, their reappearance can feel contrived rather than earned.
Reading down a column is equally revealing. A chapter that involves only one or two characters when your story typically runs ensemble might feel isolated from the main narrative. A chapter where many characters arrive at once is where the ones who matter get crowded, which is hard to notice while writing the chapter itself. The chapter numbers along the top are links, so you can open a chapter and decide whether an absence is deliberate or a character you lost track of.
Pay special attention to the first and last few chapters on either map. Characters who appear in the opening and then vanish create unfulfilled expectations. Characters who appear in the climax without adequate earlier presence feel like they were dropped in to solve problems rather than earning their role in the resolution.
