Niche research for Amazon KDP
Find the niche before you write the book.
Type one interest. NicheFlow scores 6 to 9 Amazon sub-niches for competition and profit, from 1 to 10.
Three steps from a hunch to a decision.
01
Type an interest
Anything you might write about: mindfulness, bird watching, sudoku for seniors. A word or a short phrase is enough.
02
Read the scores
NicheFlow pulls the top Amazon books for that term, then returns 6 to 9 sub-niches, each with a competition score, a profit score, and estimated BSR, reviews and price.
03
Open the full report
On Professional, any sub-niche opens into a full brief: why now, the market gap, who buys, keywords and hooks, and a 90-day plan.
About the numbers
Scores are AI judgments built from real Amazon listings, and the BSR, review and price figures are estimates. Use them to compare niches side by side, then check Amazon before you commit.
