ProWritingAid

ProWritingAid is a self-editing tool built for book-length manuscripts. Rather than correcting errors inline as you type, it generates 25+ targeted reports — covering grammar, style, repetition, clichés, pacing, readability, dialogue tags, and more — designed to be worked through systematically between drafts. The direct Scrivener integration lets authors run analysis without leaving their writing environment. The platform has since expanded beyond line editing into planning (Story Canvas), drafting (writing sessions, sprints, creative nudges), and full-manuscript story critique — though the deepest critique reports are priced separately from the subscription.

What You Get#

• 25+ writing analysis reports: Each report targets a specific dimension of your manuscript: sticky sentences, overused words, sentence length variation, adverb frequency, passive voice density, consistency, and more. Run individual reports or a full suite.
• Repetition detection: Highlights overused words and phrases across the entire manuscript, not just the paragraph you're editing. Catches blind spots that are impossible to see draft-to-draft.
• Scrivener integration: Analyze chapters or scenes without exporting to a separate file. Delivered through ProWritingAid's Desktop Everywhere app on Windows and Mac, which also drives the full-manuscript critique reports from inside Scrivener.
• Full-manuscript story critique: Manuscript Analysis, Plot Analysis, Character Analysis, Virtual Beta Reader, and Marketability Analysis each read up to 300,000 words and return structural feedback — plot and pacing issues, character arcs, reader drop-off points, and, for Marketability Analysis, a ready-made synopsis, agent query letter, and cover designer brief. These run on Story Credits, not on your subscription.
• Chapter critique: AI summarizes a chapter's strengths and weaknesses, up to 4,000 words at a time. Limited to 1 per day on Premium, 3 per day on Premium Pro.
• Lifetime plan: One-time payment eliminates recurring subscription fees — Premium lifetime at $399, Premium Pro at $699.
• Broad integration coverage: Beyond Scrivener, ProWritingAid plugs into Microsoft Word, Google Docs, Vellum, Atticus, Wattpad, Mac Notes, and Chrome, Edge, and Firefox — so the same reports follow whichever tool you draft and format in.

Who It's For#

• Novelists doing deep revision passes: The report structure is designed for focused editing sessions, not passive background checking. Most effective when used between draft completions.
• Budget-focused long-term users: The lifetime plan at $399 breaks even against the annual subscription in roughly 3 years — meaningful for authors planning to self-publish multiple books.
• Scrivener users: The tight native integration is a genuine workflow advantage. No other major editing tool matches it.

Pricing: Free plan limited to 500 words per submission, 2 runs per report per day, 10 Rephrases per day, and 3 Sparks per day. Premium: $30/month, $10/month billed annually ($120/year), or $399 lifetime — unlimited word count and report runs, 5 Sparks per day, 1 Chapter Critique per day. Premium Pro (adds live workshops, a 200+ on-demand workshop library, 50 Sparks/day, and 3 Chapter Critiques/day): $36/month, $12/month annually ($144/year), or $699 lifetime. Annual and lifetime plans include a 3-day money-back guarantee; monthly plans are non-refundable but can be cancelled anytime.

Story Credits (billed separately): Manuscript Analysis, Plot Analysis, Virtual Beta Reader, and Marketability Analysis are not included in any subscription tier. Each run costs 1 credit and covers a manuscript up to 300,000 words. New accounts receive 1 free credit. After that, list price is $50 per credit, $145 for 3, or $450 for 10. Premium subscribers pay $35 / $100 / $300 for the same packs; Premium Pro pays $25 / $70 / $175. Credits do not expire and are non-refundable.

Strengths#

• Fiction-specific analysis: Reports on dialogue tag variety, pacing variation, and genre-specific clichés that generic grammar tools don't catch. More suited to book manuscripts than Grammarly.
• Habit identification: Running reports across a full manuscript reveals writing patterns — repetitive sentence openers, word frequency spikes, overused phrases — enabling systematic long-term improvement.
• Structural feedback, not just prose mechanics: The critique reports evaluate plot, character arcs, and reader experience across a whole book — territory most AI editing tools don't enter. Useful as a pre-read before paying a developmental editor.
• Lifetime pricing: A meaningful differentiator in a market dominated by SaaS subscriptions. For authors publishing consistently, the math favors it.

Limitations#

• Deep story analysis costs extra: The full-manuscript critique reports are gated behind Story Credits on top of whatever you already pay. One pass over one novel runs $25–$50 depending on your tier, and revising then re-running multiplies that. Budget for it separately — a lifetime license does not include it.
• No mobile app: Analysis requires the desktop browser or Windows/Mac desktop app. ProWritingAid confirms it offers no iOS or Android app and points mobile users to the web editor — a notable gap compared to Grammarly.
• Feedback volume can overwhelm: Running all 25+ reports generates hundreds of suggestions across a full manuscript. Requires discipline to prioritize which reports matter for a given revision stage.
• Not passive: Must actively open ProWritingAid and run a session. Does not work silently in the background during writing the way Grammarly does.
• Free tier is barely functional for manuscripts: The 500-word cap makes meaningful novel-length work impossible without paying.
• Sub-feature word caps: Chapter Critique handles 4,000 words per run and the plagiarism checker 2,000 words per check, so full-book passes with either mean repeated runs.

Alternatives#

Grammarly is faster, more passive, and better integrated for day-to-day writing across devices, but lacks ProWritingAid's fiction-specific depth. AutoCrit is a direct competitor for fiction prose analysis at a higher price point. Fictionary focuses purely on scene-level story structure and includes its structural analysis in the subscription rather than charging per manuscript pass. None of them offers a lifetime purchase option.
