How do I add my own real story or experience to a chapter?

From version 1.9.18, open the chapter in the editor and press "Start the interview" in the "Interview me" card at the top right. BookyAI reads the chapter as it is and proposes three to five places where something you lived would make the idea land, each with the first question it would ask. Pick one, or name your own under "Something else I want to tell". Then it asks one question at a time, each picking up what you just said, and you answer in your own words. The "Your story" meter on the right shows what your story already has: where and when, who was there, what happened, what you felt, what it means now. When there is enough, press "Write it into my chapter". You see the passage where it will go in the chapter, and "Put it in my chapter" places it in the editor. "Undo last AI edit" brings the chapter back in one click.
