Your prose, perfected.
Your voice, intact.
The only editing tool that learns how you write before touching a word. Full manuscript copy and line editing for indie fiction authors — in minutes, not months.
Prose Audit works completely on its own. No other tool or subscription required.
"Won't AI editing destroy my voice?"
Every other editing tool ignores this question. Prose Audit is built entirely around it.
"I tried Grammarly. It made my dialogue sound like a corporate email."
Grammarly is built for business writing — short sentences, plain words, nothing unusual. That is exactly wrong for fiction. Prose Audit reads your writing first. It maps your sentence rhythm, vocabulary register, punctuation personality, and deliberate quirks. Every suggestion must sound like you on a better day — or it does not appear.
"ProWritingAid keeps flagging my comma splices. They're intentional."
Prose Audit specifically identifies your intentional quirks — the comma splices, fragments, unconventional dashes — and protects them permanently. It will never correct a deliberate choice. If it cannot tell whether something is intentional, it asks you. It never just changes it.
"Human editors charge £2,000 and take eight weeks. I can't afford that."
Prose Audit delivers everything a professional copy and line editor provides — editorial letter, tracked manuscript with real Word Track Changes, auto-generated style sheet, prose report — for $39, in under an hour. Plus things no human editor can offer, like Voice DNA that travels with you across every book you write.
"I'm not sure my manuscript is ready. What if I publish too early?"
Prose Audit gives you a Publication Readiness Verdict — clear, honest, and evidence-based across six measurable metrics. Green means ready for a proofreader. Amber means one more revision pass, with exactly what to fix first. Red means here is what is holding it back, in priority order.
One redundant phrase removed, one filler word cut. Fragment rhythm preserved. Em-dash style preserved. Vocabulary unchanged. This edit sounds like the writer at her best — not like an editor.
Prose Audit is a standalone product. No other tool required.
You do not need to use any other tool to get full value from Prose Audit. Upload your manuscript, capture your Voice DNA, and receive a professional copy and line edit — start to finish, on its own.
Using Prose Audit alone
Upload your manuscript. Prose Audit captures your Voice DNA, runs a full copy and line edit, delivers your five professional deliverables, and gives you a Publication Readiness Verdict. Completely self-contained — no prerequisites, no companion tools required.
Using Prose Audit with Story Audit (optional)
If you also use Story Audit (our developmental analysis tool), your manuscript, genre, character list, and structural findings transfer automatically to Prose Audit. The line edit is calibrated to the pacing issues already identified. Two tools, one editorial pipeline — but either works independently.
Voice first. Edit second. Results in under an hour.
Everything a human editor checks. And some things they can't.
The complete set of checks — far beyond grammar and spelling.
Series authors have unique editing needs. Character descriptions drift between books. Eye colours change. Timelines contradict. Place names shift spelling. The Pro Series Bible tracks all of it automatically.

Five professional deliverables. In under an hour.
Everything a professional editor provides — in the formats editors and proofreaders actually use.
Prose Audit vs. a professional human copy/line editor
An honest comparison — what each provides, what each costs, and what each can and cannot do.
★ = exclusive to Prose Audit. Prose Audit does not replace developmental editing (Story Audit), sensitivity reading, or final proofreading of typeset pages — we are clear about where human professionals are still essential.
Built on how professional editors actually work
We did not invent a new kind of editing. We studied exactly what professional copy and line editors do — and built a tool that does all of it, voice-constrained.
Less than one hour of a copy editor's time. For your whole book.
A professional copy editor charges £30–£50 per hour and takes 3–8 weeks. Prose Audit delivers the equivalent in under an hour.
vs. £800–£2,500 + 3–8 weeks for a human editor
vs. £800–£2,500 + 3–8 weeks for a human editor
Under $15/month for unlimited editing
Prose Audit + Story Audit = the complete editorial pipeline
Prose Audit works completely on its own. If you also want developmental analysis — story structure, pacing, character arcs — Story Audit is the natural companion. Both work independently. Together, they cover everything a professional editor does.
