ProWritingAid
+ 20+ report types: grammar, style, pacing, clichés, sticky sentences
+ Native integrations: Google Docs, MS Word, Scrivener, Chrome
+ Lifetime plan ($399) is the best one-time deal in this category

− Interface feels dated compared to Grammarly or Hemingway
− Report system is powerful but requires learning investment
− Not built for SEO — zero keyword or ranking features
