Nicherr: KDP Niche Hunter

Find KDP book niches that sell without a wall of reviews, see what readers wish existed, and get titles that can rank.

Nicherr is a research tool for Amazon KDP self-publishers. It reads Amazon search results and book pages to show sales estimates, competition and reader complaints, and helps turn that research into a book. FIND A NICHE - Niche Finder: search a topic and see every book's estimated sales, royalties, reviews, price and age, with a clear niche score. - Find a book: no keyword yet? Nicherr looks for niches where new authors already sell and gives you 3 book ideas. - Presets like "New High Selling Self-Published Books" get you started in one click. DECIDE BEFORE YOU WRITE - Book Decision Report: a plain Go, Maybe or Not yet verdict, with the reasons and what would change it. - Find the gap: reads 1 to 3 star reviews to show what readers wish the top books did better. - Niche Scorecard and Category Check (spot "ghost" categories where a #1 badge brings few sales). WRITE A LISTING THAT CAN RANK - Title Lab: what the top 10 titles do, and the phrases buyers type that no top title uses yet. - Reverse Keyword Tool and Keyword Explorer: an estimated demand index for each phrase. - Listing Builder, Pre-publish Check and an AI disclosure helper. - Trademark Screen: a quick check for words already used as brands (a screen, not legal advice). TRACK AND LEARN - Watchlist: track competitors' rank, reviews and price on a schedule you choose, with alerts. - Category Snapshots and Season Watch: save Best Sellers lists over time and plan for Q4 and other seasons. - My Sales: import your own KDP reports and see how close Nicherr's estimates are to your real sales. - Learning: short guides, a glossary and a season calendar. ON AMAZON PAGES - Optional badges and a Load stats bar on search results, and a panel on book pages. Every part can be switched off. YOUR DATA STAYS WITH YOU - Everything you save stays in your own browser. No account, no sign-up, no ads, no tracking. - AI features are optional and use your own key (Gemini, OpenAI, Claude and others). Requests go straight from your browser to the provider you choose. - Nicherr Cloud is off by default. If you turn it on, only public book numbers are shared, never your keywords or saved work. All sales and royalty figures are estimates, labelled "Est.", based on Best Sellers Rank. Nicherr is not affiliated with or endorsed by Amazon.
