RodBooks builds Amazon KDP tools for puzzle and low-content publishers: 19 integrated apps for research, puzzle generation, listings, and royalties.
RodBooks helps Amazon KDP publishers research niches, generate puzzles, and ship listing-ready books from one workspace. We build for self-publishers who want print-ready PDFs, clearer niche decisions, and fewer tabs between research and upload.
Every feature is shaped by real KDP workflows: keyword validation, puzzle interiors, covers, descriptions, royalties, and launch planning across 19 connected tools.
Word Search, Sudoku, Crossword, and Maze generators with print-ready PDF export at KDP trim sizes.
Niche Finder, Keyword Research, Competition Analyzer, Trademark Checker, and Category Finder.
Title Generator, Description Generator, Backend Keywords, and A+ Content.
Cover Designer, Royalty Calculator, KDP Calendar, Amazon Ads, and TikTok Marketing.
Features are tested against researching, generating, and shipping puzzle books on Amazon, not generic AI writing workflows.
PDF exports target KDP at 300 DPI with the right margins, bleed, and structure so you can upload with fewer surprises.
Free forever for low-volume use, transparent monthly limits, cancel anytime via Polar, and a 15-day refund window if it is not a fit.
