ProWritingAid

ProWritingAid goes deeper than Grammarly: beyond grammar, it analyzes prose rhythm, sentence variety, repetitions, dialogue and readability with over 25 writing reports. It's the tool preferred by fiction authors who want editorial feedback on their entire work.

ProWritingAid is an English-language writing assistant and style editor, particularly valued by fiction writers, non-native authors and anyone producing long-form texts. Unlike standard grammar checkers, ProWritingAid generates over 25 writing analysis reports examining different text aspects: grammar and spelling, sentence length and variety, word repetitions, adverb use, dialogue and dialogue tags, rhythm and pacing, readability, clichés and much more. Each report shows flagged issues with contextual explanations and suggestions. It's available as a web editor, desktop app for Windows and macOS, and as an extension for Word, Google Docs, Scrivener (the Scrivener integration is particularly valued by fiction authors) and browsers. AI features include a rephrase tool, Sparks for text generation and Chapter Critique for structural chapter analysis. Premium Pro adds higher limits on AI features, guided writing sprints and group critique sessions. The free plan is limited to 500 words per check and 2 reports per day. In 2026 ProWritingAid restructured its plans, increasing the annual price by 52% versus the previous year.
