KDP Niche & Keyword Tool — Amazon Niche Finder & Book Research

Stop guessing which books will sell. See the numbers — right on Amazon. KDP Niche & Keyword Tool turns every Amazon search into a market research report: live BSR data, estimated sales, estimated royalties and a clear 0–100 Niche Score, computed the moment the page loads. Then a full research app takes you from keyword idea to optimized, trademark-checked KDP listing. Built for Kindle Direct Publishing sellers: fiction, non-fiction and low-content creators (puzzle books, coloring books, journals, planners, notebooks). Works as your niche finder, book sales estimator, sales rank (BSR) checker, KDP keyword tool and royalty calculator — in one extension. ━━━━━━━━━━━━━━━━━━━━━━ ON EVERY AMAZON SEARCH PAGE ━━━━━━━━━━━━━━━━━━━━━━ 🔍 A stat card under every book: BSR + category ranks, estimated sales/day and /month, estimated royalties, page count, publish date, and an Indie/KDP badge so you instantly see who you're really competing with 📊 The NICHE SCORE (0–100): demand vs competition, with a full "Why this score?" breakdown — every point explained, nothing hidden.
