FixKit AIHome / Use case
โI've always wanted to write a book but never get past chapter one.โ
AI works best as an outline partner and editor, not a ghostwriter. You bring the ideas and voice; it helps structure, draft and polish.
Help me write a [book/ebook/script] for [audience] about [topic]. Here's my pitch: [paragraph]. Give me a chapter outline with a one-line goal for each. Then draft only chapter 1 from my notes: [notes], in a plain, friendly voice. Mark facts I should verify. Stop after chapter 1.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
