ProWritingAid
Grammar checker and style editor built for serious writers, not just emails
Overview
ProWritingAid is built for people who write a lot, not just people who need a typo caught before hitting send. Its reports go deeper than Grammarly's: sentence length variation, repeated words, pacing, dialogue tags, the details that matter when you're editing a novel or a long report rather than a Slack message. The Scrivener integration is a genuine differentiator for fiction writers, few competitors support it natively.
The free plan is thin (500-word limit per check), so anyone using it seriously will land on Premium fairly fast. Pricing rose noticeably in 2026, the annual plan jumped from roughly $79/year to $120/year, a change some longtime users flagged as a steep increase. The newer Premium Pro tier adds AI coaching and live workshops, aimed more at aspiring authors than everyday professional writers, and it's priced accordingly.
Key Features

Custom Style Guides: Set house style rules so the checker flags what your team actually cares about.

Pros
Deeper Reports Than Most Grammar Tools: Pacing, overused words, and readability analysis go well beyond basic grammar checking.
Native Scrivener Support: A real advantage for novelists, most competitors don't integrate with it at all.
Lifetime Option Exists: A one-time purchase avoids the subscription treadmill entirely, unlike Grammarly.
Works Across Many Apps: Browser, Word, Docs, and desktop, not locked to one writing environment.
Cons
2026 Price Increase: The annual plan rose from about $79 to $120/year, a jump longtime users noted felt steep for the same core features.
Free Plan Is Tight: 500-word limit per check makes the free tier impractical for anything beyond a paragraph.
Interface Feels Dated: Reviewers on G2 and Capterra note the UI is less polished than Grammarly's.
Suggestions Can Be Noisy: The sheer number of reports can overwhelm new users with more flags than are actually useful.
What Makes It Unique
Built for Long-Form Editing: Unlike Grammarly which optimizes for everyday correctness, ProWritingAid's 25+ reports and Scrivener integration are built specifically for editing books and long manuscripts.
