Koberger vs PRINGEN

Koberger formats manuscripts into EPUB ebooks and print PDFs for indie authors. It imports files from Word, Pages, and Google Docs, recognizing chapters, headings, and section breaks. Authors can adjust ready-made designs, typography, spacing, chapter headings, and ornaments, then save presets for reuse. Page layouts and blocks cover title, copyright, dedication, acknowledgements, glossary, and bibliography pages. Preview ebook and paperback pages, or share a private read-only preview link with editors and beta readers. Pro exports EPUB, Print PDF, and DOCX, with bulk export for multiple books; it can also create watermarked advance review EPUBs. Saved sections and designs can carry across a series, with consistency checks. Koberger says its EPUB output passes store checks and includes accessibility information, and provides pre-export checks for common ebook problems. It runs in a browser on Windows, Mac, Linux, or Chromebook without installation. The free account supports formatting, design, layout, and preview, but finished-file export requires Pro. Pro Monthly costs $9.99 a month for one book; Pro Annual costs $59.94 a year for a catalogue.

PRINGEN is a web tool for self-publishers that creates book content, arranges pages, checks files, and exports materials for print. Its listed book types include puzzle books, activity books, journals, planners, and notebooks. After a user selects a type and theme, AI generates puzzles, clues, answer keys, and page layouts. The workflow sets margins, trim size, page numbers, and spacing to Amazon KDP specifications. Before export, PRINGEN checks trim size, margins, page count, fonts, and image resolution against KDP file rules and flags issues to fix. Exports include vector PDF, high-resolution PNG, SVG, and JPG. The site describes exports for other printers too, but says it has not tested other platforms. Free costs nothing and allows three projects and 10 AI generations monthly; exports are watermarked and for personal use only. Pro costs $29 a month and includes 200 monthly generations, unlimited projects, unwatermarked exports, and commercial rights. PRINGEN is pre-launch and invites visitors to join a waitlist.
