Frequently asked questions
Short, honest answers to the most common questions before you start.
Is Niche Pro only for Amazon KDP?
Yes. Every signal, scorecard, and workflow is built around the Amazon KDP ecosystem. Other marketplaces are not supported today.
Does Niche Pro guarantee sales?
No. Niche Pro is decision-support: it surfaces honest market signals so you can prioritize ideas with better evidence. The publishing outcome still depends on your book, your cover, and your launch.
Where does the data come from?
We combine first-party crawled book data with third-party keyword and search-volume providers. Each metric carries its source and availability, so you can trust what you see and ignore what's missing.
Can I use Niche Pro as a team?
Yes — Pro is the managed team-ready plan for higher limits and shared workspace workflows.
How does billing work?
Workspace owners, admins and billing managers can start a card-required 30-day trial in Stripe Checkout. At the end of the trial Stripe charges the selected plan and renews each billing period unless the subscription is canceled from the Customer Portal.
