What you get
Free Chrome extension built for indie KDP authors.
Multi-format pricing + BSR
Live prices for every format on a book: Kindle, Paperback, Mass Market, Hardcover, Audible. Pulled straight from the page, alongside Best Sellers Rank and category breakdown.
Keyword research
Related search phrases pulled from Amazon's own autocomplete, plus a real competition summary (total results, review-count breakdown) for any phrase you're considering. Auto-fills up to 7 ready-to-paste backend keyword slots, and each competing listing's ASIN is one click away for Sponsored Products targeting. No invented search-volume numbers.
Works on 14 Amazon marketplaces
amazon.com, .co.uk, .de, .fr, .es, .it, .ca, .com.au, .in, .sg, .ae, .nl, .se, and .pl. Every feature here works the same way on whichever Amazon site you're browsing.
