Can I use AI to write a book and still call it mine?

Yes, you can use AI to write a book and still claim authorship, but the rules depend heavily on how much creative control you actually exercised. The U.S. Copyright Office has made it pretty clear: purely AI-generated text with no human creative input cannot be copyrighted. You don't own it. But here's where it gets practical. If you're using AI as a brainstorming partner, an editor, or a first-draft generator that you then heavily rewrite, restructure, and infuse with your own voice, you're almost certainly in the clear. I've found that most authors fall into this second camp without even trying. Think of it like using a thesaurus or spellcheck — nobody questions your authorship there. The line gets fuzzy when you prompt the AI with a detailed outline, character sketches, and chapter-by-chapter instructions, then publish the output with minimal changes. In that case, you're more of a director than a writer, and copyright protection might be shaky. A 2025 ruling from the Copyright Office Review Board reiterated that the key factor is whether the human's creative choices are perceptible in the final work. My practical advice? Keep a record of your prompts, your outlines, and your edits. If you ever need to prove your creative contribution, that paper trail is gold.
