What it is
ProWritingAid analyses writing across around twenty reports: sentence length variation, pacing, overused words, repetition, readability, sticky sentences and more.
Where Grammarly nudges you inline, this produces reports on a whole document, which suits long-form work considerably better.
It is the tool I would use on a long article or a manuscript, and not the one I would leave running in my email.
What it does
The reports are the product. Sentence length variation shows you where prose becomes monotonous, repetition finds the phrase you have used eleven times, and pacing flags passages that slow to a crawl.
Grammar and spelling checking is competent and slightly behind Grammarly's in accuracy.
Integrations cover Word, Google Docs, Scrivener and a browser extension, though the experience is best in its own editor for report-driven work.
A one-off lifetime licence is available, which is increasingly rare and genuinely valuable for a tool you will use for years.

Pros and cons
Pricing
| PLAN | WHAT YOU GET | WORTH IT FOR |
|---|---|---|
| Free | Limited word count per analysis. | Testing. |
| Premium monthly or annual | Full reports and integrations. | Regular long-form writers. |
| Lifetime | One-off payment. | The version worth buying. |
| Teams | Multiple users. | Editorial teams. |
The lifetime licence is the best value here and is discounted periodically. Annual is reasonable; monthly is poor value.
The lifetime licence if you write long-form regularly. Use three reports, sentence variation, repetition and pacing, and ignore the other seventeen until you have a reason.
Alternatives
My verdict
ProWritingAid is the better tool for long-form writing and the worse tool for everyday use. The reports genuinely taught me things about my own prose, particularly how often I default to the same sentence rhythm.
Use three reports and ignore the rest. Sentence length variation, repeated phrases and pacing cover most of what makes writing dull, and the other reports mostly produce anxiety.
If you write email and short pieces, Grammarly's convenience wins. If you write articles and books, this is the more useful tool, and the lifetime licence makes it cheap over time.
