Kdpage

Publishing a book to Amazon KDP is rarely one job. It's a puzzle generator, a cover editor, a trim-size calculator, a formatting checker, and — increasingly — an AI writing tool, each in its own tab, each with its own subscription. KDPage folds that whole stack into one browser-based workspace built for people who ship books to KDP, Etsy, and IngramSpark.

What KDPage actually does

KDPage is an all-in-one publishing suite aimed at KDP authors, puzzle publishers, low-content book sellers, and Etsy digital creators. You draft manuscript content, generate puzzles, design covers, calculate KDP dimensions, and export print-ready files without leaving the platform. The output is what Amazon actually wants: 300 DPI vector PDFs sized to standard KDP trim, bleed, and gutter specs, ready to upload.

The catalogue of things you can build inside it is wider than most single-purpose tools: puzzle books, activity books, coloring books, journals, workbooks, low-content books, KDP interiors, print-ready covers, Etsy digital products, and commercial publishing assets. You keep the rights and the royalties.

The features that matter

The KDP-specific pieces are where KDPage earns its keep. The interior editor sets standard trim sizes in seconds and calculates spine width automatically, so you stop hand-checking every book against Amazon's charts. The cover studio does the same for print — drag-and-drop layout with bleed and safe-print zones enforced, exported at 300 DPI.

For puzzle publishers, the generators cover the usual staples — Sudoku, mazes, cryptograms, crosswords, word searches, Kakuro — with solution pages auto-included. The batch studio lets you import book info via CSV and export multiple interiors at once, which is the difference between publishing five books a year and fifty.

AI is bring-your-own-key. You plug in your OpenAI, Gemini, or Stability keys and pay those providers directly for manuscript generation and cover art. No platform markup on tokens, no separate AI subscription — a rare thing in this category, and worth it if you're generating a lot of art.

How it fits in your stack

If you're currently paying for a puzzle generator, a separate cover designer, a KDP dimensions calculator, and an AI credit pack, KDPage replaces the first three outright and lets you keep your existing AI account instead of paying twice for tokens. Brand and pen-name profiles are built in, which matters if you publish across a few catalogues and don't want them tangled together.

Who it's built for

• Self-publishing authors shipping to Amazon KDP

• Puzzle-book and low-content book publishers

• Etsy sellers with printable digital products

• Freelance book designers and agencies handling multiple client catalogues

• Content creators expanding into print

KDPage isn't trying to replace Scrivener for the novelist grinding out a literary manuscript. It's built for the publisher-operator side of KDP — the person who cares about spine calculations, batch exports, commercial rights, and getting fifty print-ready files out the door this month without touching six different apps.
