ProWritingAid

Deep writing analysis and improvement tool

What it does

ProWritingAid is deep writing analysis for authors and professional writers, 20+ reports covering style, readability, overused words, sentence structure, pacing, and cliches, going well beyond Grammarly's grammar-and-clarity focus into genuine craft-level manuscript feedback. It's the tool serious authors and long-form writers reach for when Grammarly's surface-level checks aren't enough.

Key features

Grammar CheckStyle AnalysisReadabilityOverused WordsPlagiarism20+ Reports

Integrates with

Chrome, Word, Google Docs, Scrivener

Who this fits

  • Authors and long-form writers wanting genuine style and craft analysis, not just grammar checking
  • Content teams doing serious editing passes on published material (blog posts, guides, books)
  • Anyone using Scrivener, the integration there is a real differentiator versus Grammarly

Who it does NOT fit

  • Anyone who wants a lightweight, unobtrusive daily writing assistant, Grammarly's interface is reported as cleaner and less disruptive for everyday quick corrections, ProWritingAid is a deeper, heavier tool by design (Source: comparison review via WebSearch summary, 2026)
  • Non-English-primary writers working in mixed-language documents, one user reported the tool tries to find errors in any language present in a document, creating significant performance impact when writing isn't purely English (Source: user report via WebSearch summary, 2026)
  • Anyone expecting fast, responsive support when something breaks, support quality is a documented weak point, one reviewer summarized it as "five-star potential and one-star support," specifically citing a bug report response described as "awful" (Source: user review via WebSearch summary, 2026)

Pricing

Per tools.json: Free (500 words per check, basic checks), Premium ~$10/mo (unlimited, all reports), Premium+ ~$12/mo (adds plagiarism checks). Confirm current numbers at prowritingaid.com/pricing.

Real gotchas

  • A specific and disruptive bug has been reported where pressing Enter erases written content with no way to undo it, forcing a rewrite from scratch, worth warning the client about saving work frequently until this is confirmed resolved on their version (Source: user report via WebSearch summary, 2026)
  • The Chrome plugin has been reported as unreliable, sometimes logging users out mid-session, don't rely on it as the sole access point for a time-sensitive editing session
  • Support responsiveness is a genuine weak point relative to the product's feature depth, set expectations that self-service troubleshooting may be needed
  • If the document mixes multiple languages, expect a real performance hit as the tool attempts to check spelling/grammar across all detected languages

Integrations that matter

Chrome extension, Microsoft Word, Google Docs, Scrivener (a genuine differentiator for authors).

Otto’s take on this tool

Recommend ProWritingAid for authors, long-form content teams, and anyone needing deeper style/craft analysis than Grammarly provides, especially Scrivener users. Warn about the reported Enter-key data-loss bug (save frequently) and set realistic expectations about support responsiveness if something breaks. For simple everyday grammar checking with a lighter, less disruptive interface, Grammarly remains the better fit.

Editor's curated reviews

703 reviews across TrustPilot - avg 4.2/5

Curated by Otto from TrustPilot public reviews (fetched 2026-08-31). 703 total reviews at a 4.2 headline (59% 5-star, 8% 1-star) - a healthy, high-volume aggregate for a paid writing/editing tool. The 5-star cluster praises manuscript analysis, long-term value, and depth vs. Grammarly-class competitors. The 1-star cluster concentrates on refund-window disclosure (monthly plans excluded from the stated refund window) and occasional wrong or overly aggressive suggestions - policy-review recommendation before purchasing anything but an annual plan. G2 and Capterra were consulted for aggregate context but not directly cited here (source-access limits). Not user-submitted on Ottomately.
