ProWritingAid
FreemiumAI writing assistant for everything you write
About ProWritingAid
ProWritingAid is a grammar and style checker that goes significantly deeper than Grammarly — it analyzes writing across 20+ dimensions including sentence length variation, overused words, pacing, dialogue tags, clichés, redundancies, and readability. The reports are comprehensive: a style report shows sentence rhythm patterns, an overused words report highlights your personal crutch phrases, and a structure report maps chapter and section flow. It integrates with Microsoft Word, Google Docs, Scrivener, and Chrome. The AI rephrasing feature rewrites selected passages and generates alternatives. Pricing is $10/month or $79/year for Premium — there is also a $399 lifetime license that appeals to writers who do not want a recurring subscription. A free tier provides basic checking with limited suggestions. Reddit's writing communities consistently recommend ProWritingAid for fiction writers and novelists specifically: the long-form analysis features like pacing reports and overused phrase detection are more useful than Grammarly's sentence-level grammar focus. Business writers often find the depth overwhelming. The integration with Scrivener is unique — Grammarly does not support Scrivener at all.

Who Is This For?
Hands-on tested May 2026
Signup Experience
Email signup with free tier available -- no credit card required. Web editor available immediately after signup. Word processor integration via Chrome extension for Google Docs and a desktop app for Microsoft Word and Scrivener. First style report on a test document generates in under 30 seconds.
For Home Users
Free tier checks up to 500 words per analysis -- enough for short pieces but limiting for novelists or long-form writers. Premium at $10/mo or $79/yr (or $399 lifetime) unlocks full document analysis. The style, pacing, and overused-words reports are genuinely deeper than Grammarly for long-form content. The best value for fiction writers who want more than grammar checking.
For Business Users
Teams plan at $6/user/mo covers style consistency across a writing team. The 20+ report types are more useful for editorial teams than for business writing -- the depth that fiction writers love can feel excessive for email and report writing. Grammarly Business is the better choice for corporate teams needing fast, lightweight feedback. ProWritingAid wins for publishing, editorial, and content agencies doing long-form work.
Our Verdict
ProWritingAid is the better tool for fiction writers and long-form content — the depth of analysis and Scrivener integration make it the clear choice over Grammarly for novelists. Business writers are usually better served by Grammarly's faster, simpler feedback loop. At $79/year or a $399 lifetime license, the pricing is competitive and the lifetime option is rare in this category.
