KDP Niche Checker

Type a book idea and get an honest read before you write a word: live Amazon search suggestions (what shoppers are typing right now) plus a verdict on demand, competition, how to stand out, and narrower sub-niches with better odds. Free, no account.

How it works

The demand data comes straight from Amazon's own search suggestions for your topic's keywords — the same autocomplete real buyers see in the Books department. An AI analyst then reads those signals and gives you the assessment a blunt publishing friend would: including "don't write this one." Roughly half of all book ideas deserve that answer, and hearing it before you publish is the whole point of niche research.
