Your Book Pro vs Grammarly
They do different jobs. Grammarly Excellent general-purpose writing assistance, everywhere you type. Your Book Pro is the editorial process — planning, structural feedback, a simulated beta read, editing, proofreading, a cover and a print-ready file. Most authors who ask this question should use both, and the export here is built so they can.
Side by side, honestly
Grammarly's own published pricing, September 2026. We have not tried to make this flattering — a comparison you cannot trust is worth nothing to either of us.

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 Grammarly is genuinely good at
Excellent general-purpose writing assistance, everywhere you type. For emails, reports, applications and everyday professional writing, it is hard to beat and most people who use it should keep using it.
What these tools do instead
Grammarly is built for general prose, and a book is not general prose. It does not know that your character speaks in dialect on purpose, that your invented term is capitalised a particular way, that a fragment is doing rhythmic work, or that the repetition in chapter nine is deliberate. Applied uncritically to a manuscript it will smooth exactly the things that make the book yours.
The tools here are built for books specifically: Proofread reports rather than rewrites, Light Edit removes filler without touching your wording, and the Book Dictionary holds your book's own conventions so nothing 'corrects' them.
The part people miss
And Grammarly does nothing at the level a book actually fails at. No structural read, no beta read, no sense of whether chapter fourteen earns its place.
How to use both
Keep Grammarly for everything else you write. Use the book tools on the book — and be careful about accepting general-purpose suggestions inside dialogue.
Plus lets you upload a manuscript you wrote anywhere, run whichever tool you actually need, and export it again. That is what makes keeping both tools a real option rather than a polite fiction: your book does not have to move house to get edited. A plain export of your own words is free forever.
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.
Every account starts with 1,000 welcome credits that never expire, so a whole-book structural review — normally 900 credits for a 60,000-word book — costs nothing the first time. credit packs are there when you need more.
And the honest limits are on every tool page, not hidden: real beta readers in your actual audience tell you things no simulated reader can; a cover designer who knows your shelf will outsell a generated cover; a publishing solicitor is the answer when a book names living people. We would rather say so here.
