Overview
ProWritingAid is a writing editor and style analyzer aimed at long-form writers rather than instant-message polish. Where most checkers stop at grammar and tone, ProWritingAid runs more than 20 dedicated reports, sticky sentences, sentence-length variety, overused words, pacing, dialogue tags, and echoes, that surface craft-level problems a quick fixer never catches. It integrates directly with Scrivener, Microsoft Word, Google Docs, and Chrome, so fiction authors and academics can analyze an 80,000-word manuscript in place instead of exporting and re-importing.
Each suggestion comes with an explanation of why it was flagged, which is why non-native English writers and self-editors value it: you learn the rule, not just the correction. In our evaluation its sweet spot is exactly the work Grammarly under-serves, book-length drafts and content where structure matters as much as correctness. The 2026 pricing added a Premium Pro tier and raised annual Premium to $120/year, but the one-time $399 lifetime license remains, paying for itself in roughly three years versus the subscription.

Comparison
vs. Grammarly: Grammarly is faster and follows you everywhere, including mobile, with strong real-time tone correction. ProWritingAid wins on report depth and Scrivener integration for long-form work, and undercuts Grammarly’s annual price while offering a lifetime license.
vs. QuillBot: QuillBot centers on paraphrasing and summarization at a lower price, but it lacks ProWritingAid’s manuscript-structure reports. Choose QuillBot for quick rewording, ProWritingAid for editing a draft seriously.
vs. Wordtune: Wordtune is a fluent rewriting assistant strong on tone, whereas ProWritingAid is a diagnostic editor that explains craft issues. Pick Wordtune to reshape a sentence, ProWritingAid to understand why your writing drags.
