Twenty reports, and the four that earn their keep
The report count is a marketing number. Most writers use a handful and ignore the rest, and these are the four that consistently change a draft.
Repeats and Echoes. Every writer has crutch words they cannot see. This report finds the word you used four times in one paragraph and the phrase that opens six consecutive sentences.
Sticky sentences. Flags sentences padded with glue words — prepositions, articles, filler — that carry no meaning. Reducing glue density is the single fastest way to tighten flabby prose.
Pacing. Marks passages that read slowly: long descriptive stretches, introspection, low action. Useful precisely because a writer deep in a manuscript cannot feel their own pacing any more.
Dialogue. Shows the ratio of dialogue to narration chapter by chapter, which is how you discover that the middle of the book is 400 pages of people thinking.
Reading the reports without sanding off your voice
This is the discipline the tool demands, and the place inexperienced users damage their own writing.
Every report produces a score, and every score can be improved by making the prose more conventional. Chase all of them and you will end up with clean, correct, characterless text — short sentences, no repetition, no passive voice, no long paragraphs, and no author.
The reports are diagnostic instruments, not a marking scheme. Repetition is sometimes rhythm. A long slow passage is sometimes the point. The correct response to a flag is to look, decide, and frequently reject.
Where the reports are unambiguously right is the unconscious stuff — the word you did not know you overuse, the sentence that reads badly because it accumulated clauses over four revisions.
The Scrivener connection novelists actually use
Serious long-form writers tend to draft in Scrivener, and ProWritingAid can open a Scrivener project directly rather than requiring an export-check-reimport cycle.
For a 100,000-word manuscript held in dozens of separate scene documents, that difference is not cosmetic. It is what makes running the analysis a normal part of revision rather than an occasional chore.
The Word add-in and browser extension cover everything else, but the Scrivener path is the one that explains the tool’s audience.
ProWritingAid vs Grammarly for fiction writers
The question comes up constantly, and the answer is not close for anyone writing a novel.
Grammarly is optimised for professional communication: emails, reports, posts. Its clarity engine actively dislikes the things fiction does deliberately — fragments, dialect, repetition for rhythm, long sentences that build.
ProWritingAid was designed with fiction in mind. It still flags those things, but it also provides the structural reports that fiction actually needs, and its explanations teach rather than merely instruct.
For a working day of mixed correspondence, Grammarly’s everywhere-at-once model wins easily. For a manuscript, it is the wrong instrument.
The lifetime licence, and whether it is a good idea
ProWritingAid is unusual in offering a one-time purchase alongside subscriptions. For a novelist who will be revising for years, the arithmetic is straightforward and favourable.
Two cautions. A lifetime licence covers the software, not the AI features, which have generally been metered separately as they were added. And “lifetime” means the product’s lifetime, not yours — a rule that applies to every perpetual licence ever sold.
Where it frustrates people
- It is slow on long documents. Full analysis of a novel takes real time, and the tool works in chunks rather than one pass.
- The interface carries a lot at once. Twenty reports and a dense summary screen is more than a first-time user needs.
- Suggestions require reading. That is the point, but it is slower than clicking accept.
- Overcorrection is a real risk for writers who treat the scores as targets.
- Not built for quick checks — for a two-line email it is heavy machinery.
Your manuscript stays yours
The tool analyses documents that live elsewhere — in Scrivener, Word, or your own files — and returns comments. There is no proprietary project format holding your book hostage, which matters more for a five-year manuscript than for a blog post.
Text is processed on ProWritingAid’s servers, so the same confidentiality question applies as with any cloud checker. The desktop application reduces the friction but does not make the analysis local.
Who should choose it
Novelists and long-form non-fiction writers, first and foremost. Anyone revising a book-length work who has lost the ability to see it clearly. Writers who want to understand why a suggestion was made rather than simply accept it — the explanations are genuinely instructional and improve the writer, not just the draft.
Not the right choice if you mainly write short professional messages, or if you want corrections applied with as few decisions as possible.
Other tools for manuscript revision
- Grammarly — better for correspondence, present in every application.
- Sudowrite — for generating fiction rather than analysing it.
- Wordtune — alternatives for a sentence you cannot get right.
- QuillBot — rephrasing and summarising, aimed at students.
