The tools

Everything your manuscript needs.

Three studios, built for the work writers actually need done. Upload your manuscript once — use them all.

Copy Editor
Your manuscript,
edited closely.

A three-pass copyediting system — style sheet, edit, consistency sweep — built on Chicago Manual of Style rules. Returns native tracked-changes .docx files you open straight in Word.

  • Detects your style first — serial commas, em dash spacing, dialogue — before changing anything
  • CMOS rules with error, warning, and query severity levels
  • Style sheet pass is always free
$1 per 1,000 words Learn more
Manuscript Studio
Every document
your book needs.

Six tools built from your manuscript: back-cover pitch, publishing profile with comp titles, query letter, character bios, book club guide, and standout quotes for promotion.

  • Query letter and pitch built from your actual text — not a template
  • Character bios with voice, personality, physical description, and image prompts
  • Genre, comp titles, and Amazon category positioning
From $1 per tool Learn more
Beta Readers
Distinct readers.
Distinct perspectives.

A growing roster of reader personas — each with their own tastes, priorities, and reading lens — give chapter-by-chapter feedback and a full narrative assessment of your manuscript.

  • Chapter-by-chapter notes and a closing narrative assessment
  • Consistent perspective — the same reader, the same standards, every time
  • Run multiple readers on the same manuscript to compare perspectives
