KDP Quick Insights — Amazon BSR, Sales Estimator & Niche Research

KDP Quick Insights is a Chrome extension for Amazon KDP authors, self-publishers, and indie publishers who want book market research, sales estimates, and royalty calculations directly on the Amazon page — no separate app, no tab switching, no spreadsheets. Built as a lightweight alternative to Publisher Rocket and KDSpy, it overlays Best Sellers Rank (BSR), estimated daily and monthly sales, royalty per sale, and an at-a-glance Opportunity Score onto every Amazon search result and product page. Whether you publish Kindle eBooks, paperbacks, hardcovers, or audiobooks, the data appears inline so you can evaluate a niche or size up competitors in seconds.

WHO IT'S FOR Kindle Direct Publishing authors, low-content and medium-content publishers, and anyone doing competitor analysis or category research on Amazon without the budget for a full desktop suite. Estimates are derived from Best Sellers Rank using publicly documented KDP royalty structures. They're directional, not guaranteed — useful for comparing ideas and competitors, not a substitute for your KDP dashboard.
