Ask us a question
Do I still need the website?

The extension helps while you browse Amazon. Use the website for broader tasks such as title discovery, category comparisons, and tracking.

Does no detected audiobook mean I can publish one?

No. Check the editions and rights separately. An availability signal does not grant permission to publish someone else's work.

Are the sales figures exact?

No. Estimated sales help you compare books. They are not a publisher's actual sales records.

Give your next book a better starting point.
