Compare ProWritingAid's Free, Premium, and Premium Pro plans, including lifetime pricing, and see how its writing reports compare in 2026.
ProWritingAid is an English-language writing assistant founded by CEO Chris Banks and headquartered in Oxfordshire, England, with a registered office in London. The company employs roughly 50 people and has built its product specifically around long-form writing, positioning it as a tool for novelists, academics, and business writers who want deeper craft feedback rather than just quick grammar corrections.
The tool supports General, US, UK, Australian, and Canadian English but does not currently support non-English languages, a deliberate scope decision that lets the company focus on depth of English-language analysis rather than breadth of language coverage.
ProWritingAid's core differentiator is a library of more than 25 in-depth writing reports that go beyond simple error flags, covering areas like sentence length variation, overused words, pacing, cliches, passive voice usage, dialogue tags, and overall readability. These reports are designed to teach writers about their own patterns and habits over time, not just correct individual mistakes.
The tool integrates as a browser extension and through native add-ins for Microsoft Word, Google Docs, and Scrivener, making it especially popular with fiction writers who draft inside dedicated writing software. Premium tiers add AI-powered rephrasing, chapter critiques, a citations manager, and an author comparison tool that benchmarks a writer's style against published authors.
ProWritingAid restructured its pricing in 2026, raising its annual Premium plan from $79/year to $120/year (about $10/month) while introducing monthly ($30/month) and one-time lifetime ($399) purchase options. A new Premium Pro tier was also introduced at $36/month, $144/year, or a $699 lifetime purchase, adding higher AI usage limits and access to live author workshops.
A Free plan remains available with a 500-word submission limit and two report runs per day. Both paid lifetime purchases include a 3-day money-back guarantee, and even after the 2026 price increase, ProWritingAid's annual plan remains slightly below Grammarly Premium's $144/year list price.
Premium costs $30/month, $120/year, or a $399 one-time lifetime purchase; Premium Pro costs $36/month, $144/year, or a $699 lifetime purchase.
