About

Pubscout — Book Market Research, Right Where You Work
Pubscout overlays book market data onto Amazon search and product pages, so you can research a niche without leaving the page you're already on.

WHAT PUBSCOUT SHOWS YOU
Sales Estimates Estimated daily and monthly sales for every book in a search result, so you can see how a title is performing before you decide to compete with it.

Revenue Calculator Enter a planned price, page count, and format. Get a projected per-sale royalty and monthly income, with print costs handled across supported marketplaces.

Opportunity Score Each book gets a score based on rank, review count, publisher type, and book age — a quick read on which titles look like soft spots.

Niche Difficulty Treats a whole search results page as a niche and gives it an overall entry difficulty, so you can tell at a glance whether a market is open or saturated.

Listing Analyser Scores any book product page across eight dimensions — title coverage, description, A+ content, images, and review signals — so you can compare your listing to what's working.

Keyword Suggestions Type into Amazon's search bar and see related search-term suggestions with volume and competition signals, to help find long-tail terms worth targeting.

Summary Bar Each search page gets an aggregate strip — average rank, average reviews, average price, total estimated sales, and overall difficulty — for sizing up a market in seconds.

HOW IT WORKS
Pubscout runs entirely within your browser as you browse Amazon. It enriches the search results and product pages you're viewing with proprietary scoring models, and displays the results as non-intrusive overlays on the tiles and product pages you're already looking at. No separate dashboard to log into. No copy-pasting ASINs. Research happens at the speed of browsing.

PLANS
Pubscout offers a free trial and paid plans. Higher tiers unlock more searches per day, deeper analysis, and CSV export. Visit pubscout.app for current plan details.

PRIVACY
Pubscout does not collect, store, or sell your Amazon browsing history. All processing happens locally in your browser to power its scoring features. See our Privacy Policy at pubscout.app/privacy.
