Your prose, perfected.
Your voice, intact.
The only auditing tool that learns how you write before touching a word. Full manuscript auditing for indie fiction authors — in minutes, not months.
Prose Audit works completely on its own. No other tool or subscription required.
"Won't AI auditing destroy my voice?"
Every other auditing 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 $2,500 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 audit sounds like the writer at her best — not like a human 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 audit — start to finish, on its own.
Using Prose Audit alone
Upload your manuscript. Prose Audit captures your Voice DNA, runs a full audit, 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 audit is calibrated to the pacing issues already identified. Two tools, one editorial pipeline — but either works independently.
Voice first. Audit 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.
Words matter — here's exactly what we mean (and what we don't).
- Prose audit (what we do)
- An AI-powered diagnostic pass on your full manuscript. We surface issues, suggest fixes as tracked changes, and protect your Voice DNA — you stay in control of every accept/reject.
- Copy edit (human editor)
- A human editor rewriting at sentence level for grammar, clarity, and consistency. Slow, expensive, and we don't compete with that — Prose Audit makes your manuscript ready for it.
- Line edit (human editor)
- A human editor reshaping prose for rhythm, style, and voice. Highly creative work that belongs to your human editor. Our audit doesn't replace it — it sharpens what you hand over.
- STET (Latin: "let it stand")
- A traditional editor's mark meaning "ignore this — leave it alone." Prose Audit's STET system automatically flags your comma splices, fragments, and unconventional punctuation as protected style choices so no auditing pass ever rewrites them.
- Voice DNA
- A fingerprint of your prose — sentence rhythm, lexical signatures, punctuation habits, intentional quirks. Captured once and used as a hard constraint on every suggestion so your voice is preserved.
- Style sheet
- A document recording every editorial decision in your manuscript: character-name spellings, punctuation conventions, invented terminology, and STET-protected quirks. Send it to your human proofreader.
- Tracked changes (DOCX)
- A Microsoft Word file with every suggestion as a tracked insertion or deletion plus comment bubbles. You accept or reject each one — nothing is ever auto-applied.
- Editorial letter
- A 600–900 word narrative letter summarising what your audit found, what was changed, and clear next steps in priority order.
- Proofreader brief
- A one-page PDF handover for your human proofreader: style sheet summary, intentional quirks, what was changed, and what was flagged but left to human judgement.
Prose Audit delivers a report, not a rewritten manuscript. Your file is never altered. You stay in full control of every change.
- ✓ What you get
- •A structured audit report — every issue with its exact chapter, paragraph and sentence location
- •Suggested revisions with a marked-up diff and a rationale for each one
- •Voice DNA, style sheet, opening-pages analysis and an editorial letter
- •A tracked-changes DOCX listing every suggestion, plus PDF and Markdown report exports

- •Auto-applied changes — you accept or reject every suggestion yourself in Word/Scrivener/etc.
- •A replacement for a human copy editor or line editor — we surface the work, you (or your editor) do it

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 auditing. 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 $40–$65 per hour and takes 3–8 weeks. Prose Audit delivers the equivalent in under an hour.
vs. $1,000–$3,200 + 3–8 weeks for a human editor
vs. $1,000–$3,200 + 3–8 weeks for a human editor
Under $15/month for unlimited auditing
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.
