ProWritingAid

ProWritingAid is the self-editing tool built for fiction authors, pairing a grammar and spelling engine with manuscript-level reports on pacing, sentence variation, dialogue tags, repetition, sticky sentences, and clichés. Its native Scrivener integration through the Desktop Everywhere app is unique among grammar checkers. Since mid-2026 it also sells AI full-manuscript story critiques, priced separately from the subscription as "Story Credits."

What You Get#

• 25+ writing reports: Grammar, style, repetition, clichés, pacing, readability, and dialogue tags, run individually or as a full suite.
• Genre benchmarking: The Summary and Pacing reports compare your manuscript against published books in 15+ genres. The "40+" figure some review sites quote is ProWritingAid's count of document types (novel, short story, screenplay, academic paper), a separate feature.
• AI rephrase and critique: Sparks and Rephrase suggest rewrites; Chapter Critique summarizes a chapter's strengths and weaknesses, 4,000 words per run.
• Story Credits (billed separately): Manuscript, Plot, and Character Analysis, Virtual Beta Reader, and Marketability Analysis each read up to 300,000 words and return structural feedback: plot and pacing problems, character arcs, reader drop-off points, and a synopsis and query letter.
• Real-time collaboration on every tier: Share a Web Editor document and edit simultaneously with live cursors and viewer/commenter/writer roles — free accounts included.
• Integrations: Scrivener (via the Windows and Mac Desktop Everywhere app), MS Word, Google Docs, Vellum, Atticus, Wattpad, Mac Notes, and Chrome, Edge, and Firefox extensions. No Safari extension, and no iOS or Android app.

Who It's For#

• Novelists doing deep revision passes: Built for focused editing between drafts, not passive background checking.
• Scrivener users: The native integration is a workflow advantage no other grammar tool matches.
• Career self-publishers: Lifetime Premium breaks even against the annual plan in about 3.3 years, which pays off across multiple books.

Pricing: Free is capped at 500 words per submission, 2 report runs per day, 10 Rephrases, and 3 Sparks — no Chapter Critique, no Story Credit reports. Premium is $30/month, or $10/month billed annually ($120/year), or $399 lifetime (unlimited words and report runs, 5 Sparks/day, 1 Chapter Critique/day). Premium Pro adds live workshops, a 200+ on-demand workshop library, 50 Sparks/day, and 3 Chapter Critiques/day for $36/month, $12/month annually ($144/year), or $699 lifetime. Story Credits cost extra on every tier: 1 credit runs one report on a manuscript up to 300,000 words, list $50, $145 for 3, or $450 for 10 — discounted to $35/$100/$300 for Premium and $25/$70/$175 for Premium Pro. New accounts get one free credit; credits never expire and are non-refundable. Annual and lifetime plans carry a 3-day money-back guarantee; monthly is cancel-anytime with no refund. A Teams plan (2–100 seats) runs $12/user/month billed annually.

Strengths#

• Fiction-specific analysis: Dialogue-tag variety, pacing, and genre-benchmarked clichés — Grammarly and LanguageTool are general-purpose and routinely flag intentional fragments and dialect.
• Lifetime pricing: $399 or $699 one-time in a market of forever-subscriptions; it beats Grammarly Pro's $144/year inside 3–5 years.
• Explicit no-AI-training policy: "We will never use your writing to train our algorithms" (prowritingaid.com/responsible-ai), covering both the analysis reports and the generative features — and the generative ones can be switched off while the reports keep working.
• Third-party ratings: Trustpilot 4.3/5 across roughly 660–670 reviews as of August 2026, G2 4.5/5 (49 reviews), Capterra 4.7/5 (498 reviews).

Limitations#

• The free tier cannot touch a manuscript: 500 words per submission makes novel-length work impossible without paying.
• Deep story analysis costs extra on every tier: One pass over one novel runs $25–$50 in Story Credits, and a lifetime license includes none.
• Short refund window: 3 days on annual and lifetime plans; monthly has no refund at all.
• No mobile app, and a name-alike trap: The help center (updated February 22, 2026) confirms there is no iOS or Android app. The App Store listing titled "Prowritingaid" is actually "Proofread AI" from an unrelated developer.
• Feedback volume overwhelms: All 25+ reports on a full manuscript generate hundreds of suggestions, and false positives are a recurring complaint in reviews — expect to curate rather than accept.
• Not passive: You open the tool and run reports; it does not check silently in the background the way Grammarly does.

Alternatives#

Grammarly is faster and more passive with a free browser extension, but it is general-purpose and defaults AI training on for free and individual Pro accounts ($144/year). AutoCrit is the closest fiction-specific competitor (around $180/year) but sells no lifetime license. Hemingway Editor ($19.99 one-time) is stronger on plain readability with no manuscript-level awareness. LanguageTool is the pick for non-English manuscripts, and Fictionary works on story structure alongside ProWritingAid rather than replacing it.
