KDP Metric is a free Chrome side panel that reads whatever Amazon page you're on and turns it into a real verdict: niche grade, competition score, review targets, and which category a book should actually rank in. No invented search-volume numbers.. It mines Amazon's own autocomplete for keyword ideas and reads Kindle Unlimited signals so you know what a niche really pays. Pro adds a book audit with a fix list and an on-device AI assistant, nothing leaves your browser. No account needed, ever.

I got tired of doing the same manual checks every time I looked into a new book niche on Amazon, opening ten listings, writing down ranks, guessing at sales, counting reviews, working out which category a book was actually winning in. It's all public data. It's just scattered across a dozen page loads. KDP Metric is a Chrome side panel that reads whatever Amazon page you're on and does that work for you. It grades a search page on demand, competition and entry barrier, scores individual books on how beatable they are, shows review velocity and how much of page one belongs to one author or series, and mines Amazon's own autocomplete for keyword ideas. Free tier does all of that, no account needed. Pro is a one-time $59 and adds an on-device AI assistant (runs in your browser, nothing gets sent anywhere) plus a keyword and metadata builder. Would love feedback, especially from anyone who's used Publisher Rocket or KDSpy and can tell me what's missing.

Love the direction behind KDP Metric — Amazon book niche research. “Grades any Amazon niche A-F, free, right in Chrome” feels like a thoughtful problem to solve—congratulations on the launch! 🚀

@leon_ostrez Thanks so much! I really appreciate you taking the time to check it out. The goal was to make Amazon niche research fast and accessible without leaving the browser. I'd love to hear any feedback if you get a chance to try KDP Metric!
