You used AI somewhere in writing your book and now you're staring at the "AI Content Disclosure" step in KDP, unsure if it applies to you. It depends entirely on one distinction Amazon draws — and most authors land on the side that doesn't require disclosure at all.
This is the part that gets flattened into "you have to disclose AI now" by a lot of blog posts written to rank, not to be accurate. KDP's content guidelines split AI use into two categories, and only one triggers the disclosure requirement at publishing:
| Category | What it means | Disclosure at publish? |
|---|---|---|
| AI-generated | AI produced the substantial majority; you reviewed and approved | Yes — check the box, describe it |
| AI-assisted | You substantially wrote, edited, or directed the work; AI helped along the way | No — not required |
Brainstorming a plot with AI, then writing the book yourself: AI-assisted. Asking AI to fix pacing in a chapter you wrote: AI-assisted. Feeding AI a one-line prompt and publishing what came back with light edits: AI-generated. The test is who actually did the substantial writing, not whether an AI tool was open at any point in your process.
Amazon has been actively enforcing its content policies around AI-generated books, and the guidelines themselves have shifted more than once, which is exactly why so many authors are unsure where they stand. Getting the category wrong in either direction has a real cost: under-disclosing risks a suspension if AI-generated content should have been flagged and wasn't; over-disclosing when you didn't need to can needlessly plant doubt about a book you substantially wrote yourself.
If you land on AI-generated, here's what the disclosure should say:
If you land on AI-assisted, you don't need to disclose anything to Amazon — but a private record still has real uses (your own editing process, an agent or publisher who asks, or peace of mind if your writing is ever questioned):
Tell DisclosureTrail whether your content was AI-generated or AI-assisted, and it gives you the correct KDP wording (or tells you plainly that you don't need to disclose), plus a downloadable, dated record either way. Free, no login, nothing stored on our end.
