Grammarly vs ProWritingAid
Side-by-side comparison of features, pricing, ratings, and alternatives.
Grammarly is an AI writing assistant that checks grammar, spelling, punctuation, and style in real time across browsers, desktop apps, and mobile keyboards. It integrates directly into Gmail, Google Docs, Microsoft Word, Slack, and thousands of other websites via a browser extension. Beyond basic correctness, Grammarly analyzes tone and clarity, suggesting rewrites to make writing more concise, confident, or friendly depending on the context and audience selected by the user. GrammarlyGO adds generative AI features for drafting emails, replying to messages, and rewriting passages on demand, while Grammarly Business adds brand style guides and analytics for teams that need consistent written communication across an organization.
ProWritingAid is a writing toolkit built for authors, covering the full book-writing process from planning through editing. It includes a Story Canvas and Plot Analysis for planning, a distraction-free Write Mode with Creative Nudges for drafting, and grammar and style checking with detailed Writing Reports for line editing. Beyond grammar checking, it offers story-level critique tools such as Chapter Critique, Character Analysis, Manuscript Analysis, and a Virtual Beta Reader, plus community writing events like Novel November. It integrates with Microsoft Word, Google Docs, Scrivener, and major browsers, and is positioned around helping writers finish their work rather than writing for them.
Free for basic corrections; Premium starts at $12/month, Business at $15/user/month.

What reviewers say
Grammarly Reviews
3.0 (2)Good, not great
Grammarly is solid overall, though it's not perfect. On the plus side, good tone and clarity suggestions beyond basic grammar. That said, premium features behind a subscription, which held us back from rating it higher.
