Every other research tool assumes you already have ideas to check. Book Bolt doesn't. Our proprietary Guided Research engine reads the entire database for you and surfaces niches worth entering right now, each with a plain-English verdict: why it works, what the winners earn, and the exact book to make. We don't hand you data. We hand you the decision.
Guided Research
Niche Research
Find niches where buyers outnumber sellers
The most expensive mistake on KDP is a beautiful book nobody searched for. Scan 5M+ Amazon titles for niches with proven sales, thin competition and rising trend lines, and only create where the math already works.
Keywords with real Amazon numbers
Google measures curiosity; Amazon measures shopping. See what buyers type into Amazon, how often, and how hard each phrase is to rank for, then fill your title and all 7 backend slots with proven winners. Reverse lookup shows the exact keywords any competitor ranks for.
Keyword Tool
Bestseller Tracker
Validate on trajectory, not snapshots
A book's rank on any single day is noise. The bestseller tracker records BSR, price and reviews over weeks, so you can tell durable earners from one-day spikes before you invest a month creating, and watch your own books climb after launch.
Pick categories your book can actually win
The difference between a category needing 500 sales a day for #1 and one needing five is the difference between invisibility and an orange bestseller badge. Browse Amazon's full tree with the sales each #1 spot requires.
Category Finder
Listing Optimizer
Squeeze more royalties from every listing
Publishing is not the finish line. Every book you have published gets a health score out of 100 and a ranked to-do list: missing keywords with real volume, stronger categories, richer descriptions, biggest royalty impact first.
