Tool
Your proper nouns and invented terms, spelled the same way every time
By chapter twelve your character is Siobhán, Siobhan and Shivaun. Every copy-editor builds a style sheet on day one to stop exactly that, and nobody writing alone remembers to. This builds yours as you write, and applies it across the whole manuscript.
What it does, precisely
- Learns the proper nouns, place names and invented terms in your book
- Flags where the same thing is spelled two different ways
- Protects deliberate choices — dialect, archaic spellings, made-up words
- Builds as you write rather than being filled in up front
A separate free preview: A free outside view of your own pages
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. Send up to 5,000 words. You get back what the draft appears to be doing to somebody who wasn't there when you wrote it, the strongest thing in it named, the exact place a reader starts to drift, and three revision priorities in order.
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. An AI-assisted read of your own pages. Not a human edit, not a line edit, and not a scored report.
What it does
Most useful for fantasy, science fiction and graphic novels, where invented terminology is dense and consistency is the difference between a built world and a sloppy one.
What this looks like in your genre
fiction. Across 90,000 words a character acquires an 'h', a dog changes breed, and eye colour drifts. Readers of series fiction hold a startling amount of detail and write to tell you.
graphic novel. A graphic novel script has two vocabularies: the prose of the panel descriptions and the invented terms the world runs on. Both need to be consistent, and the second is what an artist and a letterer will follow literally.
childrens. Children's books are short, which makes people assume consistency is easy. It is not: series characters, invented words, made-up creature names and the exact phrasing of a repeated refrain all drift, and in a picture book a refrain that changes by one word breaks the read-aloud rhythm a child has already learned.
However you write
Builds from whatever is in the manuscript, whether you typed it, dictated it or uploaded it. Uploaded drafts benefit most — a book written across three years has usually drifted several times without anyone noticing.
The mistake: leaving consistency to the end
By chapter twelve your character is Siobhán, Siobhan and Shivaun. Your invented city has two spellings. The hyphen in your key technical term comes and goes. Every professional copy-editor builds a style sheet on day one to stop exactly this, and nobody writing alone remembers to.
Left to the end, it becomes an expensive search-and-replace job through 80,000 words where half the instances are legitimately different. Built from chapter one, it costs nothing and quietly prevents the problem. This matters most in fantasy, science fiction and graphic novels, where invented terminology is dense and consistency is the difference between a built world and a sloppy one.
About Your Book Pro
Your Book Pro is a book-writing platform built in Britain. Start with an idea, notes, half a draft, a podcast, or a finished manuscript, and use our purpose-built AI tools for planning, feedback, editing, proofreading, cover designs, and to create print-ready files. Writing is totally free: you can type, upload or speak your book as much as you like, and use only the editing tools you need with Plus, or go unlimited with Pro.
Produce world-class drafts at the fraction of the cost of hiring a human editorial team.
Every account starts with 1,000 welcome credits, and a plain export of your own words is free.
One rule shapes all of it. Your words are stored as Exact Text and are never overwritten. Every suggestion arrives attached to a place in your manuscript, and nothing changes until you accept it. Where most AI tools quietly rewrite you into their own register, this one shows you the change and waits. Even the automatic clean-up pass is held to a length check — if it drifts too far from what you actually wrote, the edit is thrown away and you keep your own words. The editorial standards behind the feedback are our own, written for books and specific to your genre, not a general chatbot answering in a good mood.
Book Dictionary builds your style sheet as you go rather than arriving at the end with the copy-edit — which is where it normally appears, too late to be preventative.
It can't know that Siobhán and Siobhan are the same person if you have never once written them together. It flags likely collisions; you decide.
