Hey Product Hunt! 👋
I built Wisdom Effect (https://wisdomeffectapp.com) after publishing my own puzzle books on Amazon KDP and hitting a major wall with existing puzzle generators.
Why I built it: Most puzzle book software on the market treats puzzle generation like a random number game. Especially with Sudoku, standard tools just remove random digits and call it "Hard" or "Expert"—often resulting in puzzles that either require pure guessing or are actually way too easy. On top of that, formatting margins, trim sizes, bleed, and solution pages manually takes hours of repetitive work.
As a backend engineer, I wanted to fix both the logic and the workflow from first principles.
What Wisdom Effect does & who it’s for: Wisdom Effect is an all-in-one SaaS platform built for Amazon KDP publishers, Etsy digital sellers, educators, and indie authors who want to create high-quality, print-ready puzzle books in minutes.
True Human-Logic Grading: Our custom solver grades puzzles based on actual human solving techniques (from basic singles up to advanced strategies like X-Wing, W-Wing, and Unique Rectangles), ensuring every difficulty level is 100% accurate and solvable without guessing.
Multiple Puzzle Types: Generate Sudoku, Word Search, Word Scrambles, Cryptograms, Mazes, Anagrams, or combine them into Mixed Puzzle Books.
Upload-Ready KDP & Etsy Exports: Customize fonts, grid styles, trim sizes, and page layouts, then export complete, print-ready PDF interiors with properly matched solutions.
What feedback would help most:
For anyone selling on KDP or Etsy: What is currently the biggest bottleneck in your interior creation workflow?
Which new puzzle type or customization feature should I prioritize next on the roadmap?
I’ll be hanging out in the comments all day—happy to answer any questions about the platform, KDP publishing, or the solving algorithms under the hood!
