How often each product is chosen within a category, 0–100% relative to the other.


As answered by people managing Learn JavaScript and KDPage.
KDPage's answer:
KDPage is the first all-in-one publishing studio engineered specifically for Amazon KDP creators, self-publishers, and digital product sellers. Unlike generic graphic design tools or fragmented single-purpose puzzle scripts, KDPage combines automated puzzle generation (guaranteed single-solution Sudoku, shape-masked labyrinths, crosswords, cryptograms, and word searches) with strict Amazon KDP print compliance.
Everything exported from KDPage is 100% print-ready at 300 DPI with automated gutter margin calculation, bleed safety lines, and vector PDF compilation—allowing authors to design, compile, and publish full commercial manuscripts and wrap-around book covers in minutes without touching expensive desktop software.
KDPage's answer:
Most self-publishing solutions require buying multiple standalone tools—one for Sudoku, another for mazes, a separate calculator for spine dimensions, and Photoshop or Canva for cover layouts.
KDPage replaces this fragmented stack with a unified, high-performance platform: • All-in-One KDP Toolkit: 20+ specialized generators (Sudoku, Mazes, Word Search, Cryptograms, Math Puzzles, Coloring Pages) plus cover and interior canvas designers. • 100% KDP Print Compliant: Automatic 300 DPI vector PDF exports, spine width calculators, bleed guides, and ISBN barcode generation. • Full Commercial Rights: Creators own 100% of their royalties with zero recurring licensing fees or attribution required. • Lightning-Fast Workflow: Build complete 100+ page puzzle books and ready-to-upload covers in under 10 minutes.
KDPage's answer:
The primary audience for KDPage includes: • Amazon KDP self-publishers and low/medium-content book creators. • Etsy and Gumroad digital product sellers specializing in printable activity books, educational worksheets, and puzzle bundles. • Teachers, educators, and homeschooling parents creating custom learning materials. • Independent authors, indie publishers, and digital marketing agencies scaling bulk book creation. • Side-hustlers and passive income entrepreneurs looking to publish high-converting paperback and hardcover books with zero upfront graphic design experience.
KDPage's answer:
KDPage was born out of the direct frustration of self-publishing on Amazon KDP. Creating puzzle and activity books traditionally meant juggling multiple outdated puzzle generators, manually converting files to 300 DPI, fighting with Amazon's strict bleed and gutter margin rejections, and paying expensive subscription fees for disparate tools.
We set out to build the ultimate, frictionless toolkit where any creator—regardless of technical or design background—can open a single browser tab, generate mathematically guaranteed puzzles, format perfect bleed-compliant interiors, design print-ready wrap covers, and publish directly to Amazon KDP with complete confidence.
KDPage's answer:
KDPage is built with a modern, high-performance web architecture: • Frontend & Framework: Next.js 15 (App Router), React, TypeScript, and Tailwind CSS. • Vector & PDF Engine: Custom HTML5 Canvas, SVG vector rasterizers, jsPDF, and pdf-lib for client/server 300 DPI CMYK/RGB print compilation. • Authentication & Security: Clerk Authentication with server-side cookie verification. • Database & Backend: PostgreSQL with Prisma ORM and Edge-ready serverless functions. • Billing & Merchant of Record: Paddle & AppSumo LTD licensing. • Analytics & Monitoring: PostHog and Vercel Edge Network.
