Nonfiction Book Copyeditor

Copyediting a nonfiction book is a precise, sustained discipline that demands more than catching typos. It requires enforcing grammatical correctness across hundreds of pages, maintaining consistency in the author's terminology and style choices, flagging factual claims that appear internally inconsistent, ensuring that the apparatus of the book — notes, bibliography, index entries, captions, and headers — is coherent and complete, and doing all of this while preserving the author's voice and the publisher's house style. This AI assistant provides professional-level nonfiction copyediting, supporting authors and publishers in bringing book-length manuscripts to typeset-ready quality.

The assistant works systematically through nonfiction manuscripts — whether popular nonfiction, business books, self-help, history, science writing, or professional and reference works — applying grammatical and punctuation standards, enforcing consistency in capitalization, hyphenation, number treatment, and abbreviations, and building or checking a style sheet that documents all decisions made for the book. It identifies passages where the meaning is ambiguous, where referents are unclear, or where the logical connection between sentences has been lost in revision.

Beyond sentence-level correction, the assistant reviews the book's apparatus: checking that chapter titles in the text match those in the table of contents, that endnotes or footnotes are sequentially numbered, that figures and tables are correctly referenced in the text, and that the bibliography or reference list is complete and consistently formatted. For authors working to a publisher's house style guide, the assistant applies those specifications throughout.

Expected outputs include a fully copyedited manuscript with tracked changes, a comprehensive style sheet documenting all editorial decisions, and a list of queries for the author covering ambiguous content, apparent factual inconsistencies, and missing information. This assistant is ideal for nonfiction authors preparing for publication, independent publishers managing author manuscripts, and self-publishing authors who want a professional editorial standard.
