Ruth Calloway
AI Copyeditor
Grammar, punctuation, and style consistency. Meticulous by design.
Ruth is a retired English teacher and a runner who has spent a lifetime caring about the rules because she understands what the rules are actually for. She taught literature and composition for decades and has never once confused a correction with a criticism. A correction is an act of respect: it says the writing is worth getting right.
Ruth handles grammar, punctuation, style consistency, and the stylesheet that documents every decision she makes. She is not the Proofreader: that final mechanical pass comes after her. And she is not the Line Editor: sentence-level clarity and rhythm are not her jurisdiction. She is here for grammatical and stylistic logic.
The Stylesheet Deliverable
The stylesheet Ruth produces is a deliverable. It logs every decision: capitalization, hyphenation, number formatting, terminology, with the first occurrence cited. It travels with the manuscript through every subsequent session.
Tone of Voice Feature
Ruth receives the Voice Profile from Serena Voss, calibrated to distinguish deliberate stylistic choices from inconsistencies that need correction.

Common Questions
What does a copyeditor do that a proofreader doesn't?
A copyeditor addresses grammar, punctuation, style consistency, and the construction of a stylesheet that documents every decision. A proofreader (Liam Ashby) comes after, doing a final mechanical check against the standards the copyeditor established. Copyediting is about consistency and correctness across the manuscript. Proofreading is about ensuring the final document matches those standards exactly.
What is a manuscript stylesheet?
A stylesheet is a document Ruth produces alongside her edits. It logs every style decision: capitalization of terms, hyphenation, number formatting, treatment of dates, terminology choices, and the first occurrence of each. The stylesheet travels with your manuscript through every subsequent session so every agent works from the same standard.
Can an AI copyeditor catch inconsistencies across 80,000 words?
Yes. Ruth works chapter by chapter, building the stylesheet as she goes. Because the stylesheet logs first occurrences and decisions, she catches drift: a term capitalized in chapter 3 that is lowercase by chapter 12. The stylesheet is the consistency mechanism.
When should copyediting happen in the editorial process?
After developmental editing and line editing. Copyediting is not the place to resolve structural problems or improve prose rhythm. Those must be settled before Ruth works. She handles what remains after Elliot and Tara have done their jobs.
Does the copyeditor change my voice?
No. Ruth receives the Voice Profile from Serena Voss, calibrated to distinguish deliberate stylistic choices from inconsistencies that need correction. An author who intentionally fragments sentences has a different treatment than an author who fragments sentences accidentally. Ruth knows the difference.
