BookPeek - KDP Book Niche Research + MCP

HAND YOUR BOOK RESEARCH TO YOUR AI BookPeek is an Amazon book research tool with an MCP. AI apps that support MCP (Model Context Protocol) can do the research for you, in your own browser, on your own Amazon. You approve each app once, and the connection never leaves your computer. Ask in plain English: • "Is watercolour for beginners worth writing for?" • "What do readers complain about in the top three books?" • "What would a 108-page large-trim paperback earn at $9.99?" WHAT YOUR AI CAN ASK FOR • The reviews of the books already ranking, in the readers' own words. What they complain about is the gap you write into. • The first pages of a book's Amazon sample, so your AI can see how a book is built before you outline yours. • Two to five books side by side, and what actually separates them. • Any KDP royalty: paperback, hardcover or Kindle, 8 marketplaces, both trim sizes, all four ink types. • A whole search analysed: page 1, each book opened one at a time, with a verdict and the reasoning behind it. • Your seven KDP keyword boxes, drafted from the words the ranking books already use. AND A PANEL, WITH NOTHING TO SET UP Search books on Amazon and BookPeek reads page 1 for you. • A verdict on the niche, with the reasoning and the number of books behind it • Every book's sales rank, estimated sales, age, page count and ratings • The closest category each book ranks in, which is the shelf it actually competes on • Who publishes here: self-published, a publisher, or cannot tell • Your seven KDP keyword boxes, drafted • CSV export • Saved searches that sync across your computers Open any book's page and BookPeek works out what its author earns: the printing cost, the royalty per copy, and what that comes to in a month at the rank it holds now. WHAT IT WILL NOT DO • No search volume. Nobody has Amazon's search numbers, so nobody can sell you one honestly. • Sales are always a range, never a single figure. They are estimated from each book's rank. • Every analysis says how many books it actually managed to open. A page that would not load is never counted as a book that does not sell. • When BookPeek cannot answer something, it says so instead of guessing. GOOD TO KNOW • BookPeek speaks English, Spanish, Portuguese, French, German, Italian, Dutch, Polish, Turkish, Japanese, Indonesian and Arabic. It follows Chrome's language; change it in Settings. • Amazon.com for now. • Reading reviews needs you signed in to Amazon in this browser. Signed out, Amazon hides the review text from everyone. • Reading book samples stays switched off until you turn it on in Settings. PRIVACY No account and no sign-up. Everything is read in your browser and nothing is sent to us — there is no server of ours to send it to. Your saved searches sync across your own computers.
