ProWritingAid – AI Tool | HokAI
Your personal writing coach: grammar checker, style editor, and writing mentor in one
About ProWritingAid
ProWritingAid is a comprehensive writing tool designed for authors, editors, students, and content creators who want to improve their craft beyond basic grammar checking. Founded in 2012, the platform provides 25+ detailed writing reports that analyze readability, structure, style consistency, overused words, pacing, and more—helping writers understand not just what's wrong but why and how to fix it. The tool works seamlessly with popular writing apps including Microsoft Word, Google Docs, Scrivener, and browser extensions, enabling real-time editing feedback. Unlike simple grammar checkers, ProWritingAid functions as a teaching tool that helps writers identify patterns in their work and gradually improve their skills over time. The platform serves writers across all genres and skill levels, from first-time authors tackling their first novel to professional copywriters refining business documents. Its unique selling point is the depth of analytical feedback rather than quick fixes—making it particularly beloved by novelists and long-form writers who invest time in perfecting their prose. ProWritingAid prioritizes user privacy, employing bank-level security and explicitly never using customer text to train algorithms. The service offers multiple pricing options including a free tier with basic features and paid subscriptions available monthly, annually, or as lifetime one-time purchases.
