Free KDP niche research on Amazon: niche scores, BSR, sales estimates, royalties — plus a puzzle book and notebook maker. Find a KDP niche, plan the book and make it — in one free extension. RESEARCH ON AMAZON • Niche panel on every Amazon book search: a 0–100 score split into Demand, Competition, Indie-friendly and Room for newcomers, with median BSR, estimated sales, reviews and price. • Badges under each result: rank, estimated sales, pages, publish date, publisher. • Book panel: Best Sellers Rank with history, category ranks, estimated sales and a royalty calculator that flags the $9.99 threshold. • Market analysis: new releases in the last 30/90 days and how many of them actually sell. • Buyer complaints: reads the 1–3★ reviews of top books so you know what to do better. • Listing Builder: title words top books use, 7 keyword slots, easy categories, price and page advice. • Batch research for up to 25 keywords (you start it; it runs slowly in a visible window and stops on a captcha). MAKE THE BOOK • Book Maker: word search, sudoku, mazes, word scrambles and cryptograms in English, Turkish, Spanish, German, French and Portuguese — or lined, dot-grid and graph notebooks, planners, habit trackers and logbooks with your own columns. • You get a KDP-sized interior PDF (mirrored margins, embedded fonts) and a matching full-wrap cover PDF with the right spine width. • Every book is checked the way KDP checks it: page size, page count, fonts and margins. • Every build makes fresh puzzles, and Nichesmith warns you when a book reuses shared starter words or your own earlier content. • Series planner: split your themes across volumes, raise the difficulty, add them to your board. • Promo images: 3D book, social post and Amazon A+ image. KDP TOOLS • Cover size and spine calculator with a template. • Interior PDF check, listing check (character limits, words KDP rejects) and a US price & royalty ladder. STUDIO • Book board from idea to published, notes, templates and My books (your own titles' rank and estimated royalty). HONEST AND PRIVATE • Sales figures are estimates from Best Sellers Rank and are always shown as ranges. • No account, no server, no tracking. Your research stays in your browser. • Nichesmith never scrapes in the background. It only reads pages when you ask it to. FREE • Every feature is free: no limits, no trial, no account. • If it helps your books, you can support development with an optional crypto donation (address in the Guide). It unlocks nothing — everything is already open. The interface is available in English, Türkçe, Español, Deutsch, Français and Português. Nichesmith is not affiliated with Amazon.
