Type one broad topic — planners, senior health, dogs. KDPie unfolds it into hundreds of related phrases with real Amazon search volume, grouped into clusters. You see the whole market from above: where the crowd is, where it's empty, where it's growing. A week of manual digging, in one run.
Hunt report · overnight
7 niches scored while you slept · pilot phrases visible inside
Press hunt. An agent invents niche hypotheses — or starts from your theme — runs each one through the same checks you'd run by hand, and files a scored report. You read verdicts over coffee.
Decide fast
Paste up to 200 phrases at once — the entire notes file if you want. KDPie runs each one through live demand, the current shelf and months of competitor history, then hands back a table of verdicts. Thirty browser tabs across three evenings become a list you read in ten minutes.
Anything already checked opens instantly. The base remembers every niche it has ever seen, with history.

Trust the call
Every phrase is scored by a fixed formula: demand 40 points, shelf contestability 40, production payoff 15, momentum 5 — plus hard kill gates. Dead demand or a first page locked by entrenched series kills a niche outright, however pretty the rest of the math looks. The formula is deterministic. One niche, one verdict — today, tomorrow, for you and for anyone else. No AI mood swings.
We publish our own books on these verdicts. When the formula says kill, we don't publish. No exceptions for ourselves.

That's one evening you didn't spend on a “top niche from YouTube”.

The top 10 of any shelf with covers, prices, review counts, age and BSR trend.
How much the books already on the shelf actually sell — honest monthly ranges, computed per marketplace.
How many sales per day it takes to hold #1 and #10 of any category shelf.
Watch any book by ASIN or ISBN — your own or a competitor’s. BSR, reviews, prices, plus AI suggestions grounded in the data.
A ready title, subtitle and 7 backend keywords, built from the niche’s measured phrases — plus a cover-structure brief. Copy, paste into KDP.
Paste an ASIN or ISBN and see which search queries the book actually ranks for — yours or a competitor’s. amazon.com for now.
Every check is kept: verdicts, history, your notes. “What did we decide about this niche in March?” stops being a question.
Works on 7 Amazon marketplaces — .com, .de, .co.uk, .fr, .it, .es, .ca — with demand read in the market's own language. The .de and .fr shelves are invisible to English-only tools.

Don’t — check it. The formula is open inside the product down to every weight, verdicts are reproducible, and each one arrives with its reasons. The strongest argument works against us: most checks end in kill. A tool that sells you “no” has no reason to lie.
Live Amazon search demand, the real search results page, and months of competitor sales, price and review history — professional market-data sources, included in the plan. No extra subscriptions, and no access to your KDP account is requested. Ever.
The field is millions of phrases across 7 marketplaces; what’s been checked is a fraction of a percent. Verdicts are the same for everyone, but the book, the angle and the execution are yours. And your own finds stay private until someone reaches them independently — you can’t see other people’s pilots, and they can’t see yours.
No. And run from anyone who guarantees it. Pilot means: demand confirmed, competition passable — by the data. The book is still your half of the work.
ChatGPT can’t see Amazon demand or sales history — it guesses from memory. KDPie’s agents stand on a live database, and the verdict is always computed by the formula, never by a language model.
In beta. For fiction KDPie shows shelf data and signals — series share, author concentration, entry price points — but issues no verdict. In fiction, the author decides. The formula is built for non-fiction and low-content.
The merchant of record is Paddle (cards and PayPal, EU VAT on the invoice). 14-day refund on subscriptions, less the value of the credits already used — details in the Refund Policy. Cancel any time from your account.
It becomes a paid Starter subscription automatically, billed monthly, unless you cancel before the 7 days are up. Cancelling takes one click inside your account, and the checkout shows the exact amount and currency before you confirm anything.
One topic in. A market map out, verdicts on the best phrases. For $7 you'll see your market the way years of manual research never showed it.
