KDPCheck is an informational tool, not legal advice and not affiliated with, endorsed by, or operated by Amazon.com, Inc. or its KDP division. The disclosure guidance is based on our reading of Amazon KDP's publicly published AI-content guidelines as of 2026-09-12; Amazon can change these guidelines at any time, and only the current guidelines in your KDP dashboard are authoritative. You are responsible for verifying your own compliance before publishing.
The prose pattern scan checks a pasted excerpt against mechanical writing patterns (stock phrasing, uniform sentence rhythm, repeated paragraph openers) that we believe correlate with the kind of low-effort output Amazon's own guidance describes as a quality risk. It is not an AI-content detector, has no access to Amazon's internal review systems, and a "low risk" result is not a guarantee your book will pass review — nor does a "high risk" result mean it will be rejected. This tool exists to help you write in a more distinct voice and disclose correctly, not to help anyone evade Amazon's review.
The $9 charge is one-time, billed via Stripe, for a single report. It is non-refundable once the report has been generated, since the report itself is the deliverable. If payment succeeded but no report was generated due to a fault on our end, contact us with your Stripe session ID for a refund.
The service is provided as-is with no warranty. We are not liable for decisions made based on its output, including publishing, disclosure, or editorial decisions.
