ProWritingAid
A deep style and readability report for long documents that flags repetition, pacing problems and clichés a spellchecker misses.
What you'd use it for
Running a full editorial-style report on a finished manuscript or long document to catch pacing, repetition and style problems a spellchecker won't flag.
- Run a full-document report that flags overused words, sentence-length monotony and pacing that sags across a chapter
- Get grammar and spelling checked the way a standard checker does, alongside the deeper style reports
- Rephrase a flagged sentence with alternate wording suggestions
- Build a custom style guide so the same terminology and tone get checked consistently across a long document
- Edit inside Word, Google Docs or Scrivener with a plugin instead of switching to the web editor
The verdict
ProWritingAid is built for people finishing something long, a manuscript, a proposal, a book, not for policing typos as you type. The reports go deeper than a standard grammar checker's, but that depth is wasted on short documents, and the free tier's 500-word cap stops you properly testing it on anything manuscript-length before paying. For a business-document use case the annual plan is the number to beat; the lifetime option only pays off if you're still using it in three years. It suits a writer with a finished draft to interrogate, not someone who wants help getting words onto the page in the first place.

What you need to start
- A free account, created with email, Google or Facebook sign-in
- An internet connection for every version, including the desktop app
- Windows 10 1903 or newer, or macOS Catalina 10.15 or newer, if you want the desktop app instead of the browser editor
A few minutes to sign up and get a first report on a pasted excerpt; longer to wire it into Word, Google Docs or Scrivener through the add-ins.
Your first run Paste or upload a document into the free Web Editor and run one of the two daily reports; colour-coded suggestions appear straight away, though the free tier caps each run at 500 words.
Where it breaks
ProWritingAid edits what you already wrote; it does not draft new copy from a prompt the way a general chat assistant does — it's a report on a document, not a writer of one.
Browser editor, desktop app, and plugins for Word, Google Docs and Scrivener.

When not to use it
Anyone who wants live-as-you-type correctness on emails and short messages should use a checker built for that; reports are meant to run on a finished draft, not catch a typo mid-sentence. The free tier's twice-a-day, 500-word cap makes it impractical for editing anything manuscript-length before you pay.
Grammarly gets compared to ProWritingAid so often that the actual difference is worth stating plainly: Grammarly is built for line-by-line correctness as you type, ProWritingAid is built to run a full report on a finished draft and tell you about patterns you can’t see one sentence at a time — overused words, sentence-length monotony, where the pacing sags across a whole chapter.
That report-based model is why it suits long documents better than short ones. A two-paragraph email doesn’t need a 25-report breakdown; a manuscript, a long proposal, or a book does, and that’s the audience ProWritingAid has built three million users around over more than a decade.
What the tiers actually change
Free gives you two report runs a day, capped at 500 words — enough to sample the tool, not to edit a chapter. Premium removes both limits and adds the bulk of the analysis reports; Premium Pro adds live workshops and group critique sessions on top, which is a community feature as much as a software one and matters mainly to people writing books rather than business documents.
Buying it once instead of monthly
The lifetime option is unusual for a modern SaaS product and worth noticing if you know you’ll use it for years: $399 once instead of $360 over three years of monthly billing (or $10/month annually, which is cheaper again). For a business document use case rather than a manuscript, the annual plan is the harder number to beat.
