AuthorScout (formerly KDP Scout)

See BSR, estimated sales and royalties on Amazon book pages. Filter book lists, research keywords, track books. Formerly KDP Scout.

PUBLISH WITH DATA, NOT GUESSES. You find a promising book on Amazon: the rank looks good, the reviews look low. But is it actually selling? Is it self-published or traditionally published? And what are readers searching for? AuthorScout answers those questions on the pages you already browse, so you can judge a book idea before you commit months to it. It works on 10 Amazon storefronts. ON EVERY BOOK On search results, Best Sellers, New Releases, category, author and product pages, each book gets a panel with: • Best Sellers Rank (overall and subcategory) • Estimated daily and monthly sales • Estimated royalties, where KDP royalty rules apply • Page count, book age and dimensions • Whether the publisher looks self-published Best Sellers lists load all 50 books. Free Kindle promotions are labelled free instead of showing sales. No sign-in needed. READ A WHOLE PAGE AT ONCE A toolbar above the store's book lists summarises the page: median and average BSR, reviews, book age and price by format. Book Filters narrow it by BSR, reviews, age, format, price and self-published vs traditional, and stay on as you move to the next results page. CHECK WHETHER DEMAND LASTS One good day is not a trend. • Deep Dive: BSR and price history (1M, 3M, 6M, 1Y and All views), average 30-day BSR, current BSR and price, reviews and a competition read. • BSR across marketplaces: one click shows the same book's rank on the other storefronts. • Book Tracker (Pro): follow BSR, price and reviews over time on 9 of those storefronts. FIND WHAT READERS SEARCH FOR • Keyword Expander: as you type in the store's search box, a panel shows its suggestions plus related and long-tail phrases, competing book counts and title density. Pro adds monthly search volume and a 12-month trend. New phrases are measured overnight and show "queued" until then. • Today's top book keywords: a daily list of phrases where self-published books are selling, showing how many, their average BSR and reviews, estimated revenue per book per month, and example books. Available on 7 storefronts. OPTIONAL: YOUR AI ASSISTANT You can connect AuthorScout MCP to use its book research inside Claude, ChatGPT or Grok. It only asks for access to those sites if you click "Allow access", and never reads your conversations. PLANS • Free, no account: the book panels. • Free account: adds 1 Deep Dive and 4 BSR-across-marketplaces checks a month. • Pro ($9.99/month): Book Tracker, search volume and trends, today's top keywords (top 50) and much higher monthly allowances. • Publisher Pro: higher limits again, plus the top 100 keywords.

Signed in, the extension sends the books you view (ASIN, marketplace and public book details) and what you type into the store's search box to AuthorScout's servers to provide the features. Search phrases are stored without your account attached. It never reads your Amazon account details, orders, payment info or passwords, and does not run on sign-in, checkout, cart or order pages.
