Write a book or story with AI without losing your voice

How to use AI as a writing partner (ideas, structure, characters, proofreading) while keeping your style, and what Amazon KDP requires if you publish AI-generated content.

By Cognenza editorial team · Updated · 2 min read · Sources cited

A book needs your voice. AI can be a patient editor, a brainstorming partner or a reader who spots inconsistencies. It shouldn’t be the one writing.

Useful roles

  • Questions: “What does this character want and what stops them?”
  • Structure: chapter outline, timeline, character sheets.
  • Continuity checks.
  • Proofreading. For long texts, tools like Claude take lots of context. More in write with AI.

If you publish

  • Amazon KDP: its content guidelines require disclosing AI-generated content (text, images, translations) even if edited; AI-assisted content needn’t be declared.
  • Authorship: Spain’s Intellectual Property Law protects the person who creates.
  • Real facts: AI can invent. Research in sources.

Frequently asked questions

Must I declare AI use when self-publishing on Amazon?

Per Kindle Direct Publishing content guidelines, you must disclose AI-generated content (text, images or translations), even if heavily edited; AI-assisted content (you wrote it and AI helped refine or brainstorm) needn’t be declared.

Am I the author if AI wrote part of it?

Spain’s Intellectual Property Law treats as author the natural person who creates the work. The more the text is yours, the clearer your authorship.
