Open the side panel on any Amazon book search, best-seller list or product page — the analysis updates as you browse. Free features work forever; PRO marks what the upgrade adds.
One clear verdict on whether a niche is worth entering — blending demand, competition and how reachable the entry bar is.
Plain-English guidance for newcomers: target reviews, price band (or Kindle Unlimited strategy), the rating to hold, and a clear "enter or avoid" call.
Every book scored for how beatable it is. The soft targets rise to the top of a sortable, filterable table.
Crowdsourced rank and price history on books over time — trend data a single page view can't show you.
On any book, see its exact sub-categories with a "best pick" flag — and how many daily sales it takes to reach #1.
Related keywords from Amazon's own autocomplete, each one click-to-analyse for its real competition.
Paste your working title and see how it stacks up: keyword coverage, the proven niche words you're missing, and length vs the norm.
The recurring hooks and tropes across a niche's titles, at a glance — instant inspiration for your angle.
A grid of every competitor cover on the page, so you can design something that stands out.
Pin any book — yours or a rival's — and watch its BSR & price over time from your Tracked list.
One click to Amazon's Movers & Shakers, Hot New Releases and Best Sellers — analysed instantly.
Export any analysed table to a spreadsheet — including grades, scores and estimates — for deeper work.
A clean, modern interface in light or dark mode, across all major Amazon marketplaces.
Open your own book for a Visibility grade and a prioritised, tickable fix-list — exactly why it's stuck and the next move to make.
Ready-to-paste backend keyword slots and subtitle terms, built from live Amazon autocomplete + your niche — filtered to KDP's rules.
Expert prompts pre-loaded with your niche's real data — paste into ChatGPT or Claude for instant, grounded market analysis.
Find the easiest category to break into — how entrenched the leaders are and your realistic route to a #1 bestseller badge.
A private AI assistant that runs on your device, reads your book, and guides you search-by-search to the categories and keywords most likely to rank — then writes up its recommendation.*
Export a clean report — grade, strategy, competitors, keywords and your book-audit fixes — branded with your own logo & name.
* Category Scout AI runs locally using your browser's built-in AI. It needs a compatible, up-to-date desktop browser and may not be available on every device. It's an optional convenience, and its availability depends on your browser vendor — see our terms.
The free version tells you where to publish. Pro tells you what to do about your book — and does the heavy lifting for you.
Category Scout AI sits beside any book on Amazon, reads the listing, and works through it with you in plain English — which categories it can actually rank in, which keywords matter, and what to check next. When it has enough evidence, it writes up its recommendation.
It runs entirely on your device using your browser's built-in AI. Nothing you discuss leaves your computer — no API keys, no usage fees, no cloud.*
Open any book — yours or one you're studying — and the Book Audit grades its visibility, then lists the fixes in priority order: review gap, missing proven keywords, pricing, category placement.
Export the whole audit as a clean PDF report, branded with your own name and logo — ready to act on, or to hand to a client if you offer publishing services.
The Niche AI Brief packs each expert prompt with the niche's actual top 20 titles, market stats and proven keywords. Copy a prompt into ChatGPT or Claude and get grounded, specific analysis — market intelligence, reader demographics, trends, success factors — instead of generic guesses.
Uses the AI subscription you already have. No extra limits, no extra cost.
The free version, doing what it does on real Amazon pages.
Add KDP Metric to Chrome, pin it, and open the side panel from the toolbar icon.
Search a keyword (e.g. "cozy mystery"), open a Best Sellers list, or land on any book's page.
Get the Niche Grade, Coach advice, competition table and trends — instantly, with no clicking around.
The #1 mistake new authors make is picking a niche that's already saturated. KDP Metric shows you the real competition before you spend months writing.
Review counts, ratings and competition are real Amazon data. Sales figures are clearly labelled as rough models — we show ranges, never fake precision.
Not just numbers — concrete targets: how many reviews to get visible, which price or KU strategy, which sub-category to rank in.
No account, no sign-up, no personal tracking. The core is free forever, and Pro is a single payment — no subscription quietly draining your card.
KDP Metric only reads pages you deliberately open — it never crawls, opens tabs, or needs an account. It stores no browsing history.
You can optionally contribute anonymous public book facts (rank, price, rating, review count) to build the shared trend data that benefits everyone. It's off by default, contains no personal data, and you can turn it off anytime. See our privacy policy and terms of use.
Start free — it's a complete research tool on its own. Upgrade when you want the expert book audit, the guided fix-it plan, the AI brief and the on-device AI assistant. One payment, no subscription.
