Koberger

Koberger is a browser-based manuscript formatter for independent authors producing ebooks and print editions. It is best suited to writers who want adaptable layouts, repeatable series production, and review links without installing desktop software. The free account is useful for preparing and checking a project, while export work belongs to the paid tiers.

Overview

Koberger turns files from Word, Pages, and Google Docs into a structured book project, recognizing chapters, headings, and section breaks. That saves substantial cleanup time compared with placing manuscript text into a blank layout, while still allowing the author to revise the structure and visual treatment.

The browser workflow runs on Windows, macOS, Linux, and Chromebook without installation. It combines layout, preview, and export in one service, making it a sensible choice for authors who want a consistent production process rather than a separate editor for each output format.

Key features

Design and book structure

Ready-made designs are starting points rather than locked templates. Authors can change typography, spacing, chapter headings, and ornaments, then save those choices as reusable presets. Layout blocks cover title, copyright, dedication, acknowledgements, glossary, and bibliography pages, so front and back matter can follow the same visual system as the main text.

Preview, export, and series workflow

Page previews for ebooks and paperbacks help authors inspect both reading experiences before delivery. A private, read-only link lets editors and beta readers comment on a near-final version without receiving an editable project. Saved sections and designs can be reused across books, and series consistency checks are particularly valuable for authors publishing multiple volumes.

Pro exports EPUB, print PDF, and DOCX, with bulk export for multiple books. Koberger says its EPUB output includes accessibility information, passes store checks, and receives pre-export checks for common ebook problems. It also creates watermarked advance-review EPUBs, a practical option for launch teams and reviewers. The intended storefronts include Amazon KDP, IngramSpark, Apple Books, and Kobo.

Manuscript handling and privacy

Koberger says manuscript content is not used to train AI models or supplied to AI-training systems. Its privacy policy describes manuscript and project-file processing for formatting, preview, and export, without intentionally collecting manuscript content for analytics or monitoring. Payments go through Stripe, and full card numbers are not stored on Koberger's servers. Email support covers account and export issues; including the account email, browser, operating system, and attempted task should make troubleshooting more efficient.

Pricing

The free tier is appropriate for preparing a manuscript and sharing previews, but it cannot deliver files for publication. Monthly Pro keeps the commitment lower and suits an author working on one book; its single-book scope is a meaningful constraint for a backlist or active series. Annual Pro costs less than twelve monthly payments and covers the whole catalogue, making it the stronger fit for repeat publishers. There is no free trial, so the free account is the practical way to assess the workflow before paying.

Platforms

Koberger runs in a browser on Windows, macOS, Linux, and Chromebook and requires no installation. EPUB, print PDF, and DOCX output are available through Pro.

Who it's for

Choose it for indie fiction or nonfiction authors who need both ebook and print files, want reusable design rules across a series, and value private review links and pre-export checks. It is less suitable for a one-off project if paying to export outweighs the convenience, or for authors whose monthly subscription must cover several books at once.

Pros and cons

• Pros: Imports common manuscript sources and detects structural elements, reducing initial layout work.
• Pros: Adjustable designs, reusable presets, and saved sections support a repeatable series workflow.
• Pros: EPUB, print PDF, and DOCX exports, bulk export, review-copy watermarking, and store-oriented checks cover a broad publishing pipeline.
• Pros: Browser access avoids installation, while stated manuscript-use safeguards address a key privacy concern.
• Cons: The free plan cannot export finished files, so it is not a complete no-cost publishing solution.
• Cons: Monthly Pro is limited to one book, which can force catalogue publishers onto the annual plan.
• Cons: There is no free trial; evaluation happens through the export-limited free account.

Verdict

Koberger is a strong choice for indie authors who want browser-based formatting, reusable layouts, and professional ebook and print outputs in a repeatable workflow. Its main advantage is the combination of structured import, series tools, previews, and export checks. Look elsewhere if you require finished exports without a subscription or need a monthly plan that covers multiple books.
