Pinery vs. ProWritingAid

ProWritingAid tells you about your writing — reports, scores, highlights. Prose fixes it in your writing: labeled grammar and style changes as diffs you accept or reject, inside the same app that designs and exports the book.

What ProWritingAid does better

Breadth of analysis and integrations. Its dozens of specialized reports (sticky sentences, pacing, dialogue tags) and plugins for Word, Google Docs, and browsers make it a strong final-polish companion wherever you write. If you want reports, it delivers; if you want the fixes applied — reviewably, in your own files — that's Pinery.
