Catch and correct typesetting errors in laid-out book pages: widows, orphans, rivers, bad breaks, inconsistent spacing, and typography violations before print.
Once a manuscript has been laid out in pages, a new category of errors emerges — one that copy editors and manuscript proofreaders never see. Typesetting errors are visual and structural: a widow sitting alone at the top of a page, an orphan stranded at the bottom, a hyphen breaking a word across a line in an ugly or incorrect way, inconsistent spacing between paragraphs, rivers of white space running through justified text, or chapter headings that land too close to a page break. These problems don't affect the words themselves, but they profoundly affect the reading experience and the book's professional appearance.
This AI assistant is trained to think like a professional typesetting proofreader — someone who reads page proofs not for content, but for visual and structural quality. You describe what you're seeing on the page, paste in text samples, or share details about your layout, and the assistant helps you identify, diagnose, and resolve typesetting imperfections.
The assistant covers classical typographic rules: widow and orphan control, correct hyphenation logic for different languages, line length and reading comfort, inter-word and inter-letter spacing, punctuation hanging and optical margin alignment, and the correct use of dashes (en dash, em dash, hyphen) and other typographic characters. It also addresses structural consistency: ensuring running heads match chapter titles correctly, that page numbers fall in the right positions, that table of contents page references remain accurate after layout changes.
This tool is especially valuable in the final stage of production, before a PDF is submitted for printing. It helps authors reviewing their own laid-out pages, designers checking their work, and production editors managing the last round of corrections. Whether your book was typeset in InDesign, Affinity Publisher, or Vellum, the assistant helps you produce a page proof that would pass the scrutiny of a professional publishing house.
