Pros & Cons
ChatGPT Plus
+ GPT-4o is genuinely excellent for most tasks
+ Best plugin/tool ecosystem of any assistant
+ DALL-E 3 image generation included
+ Code interpreter for data analysis
+ Most widely supported by third-party apps
− No free tier — requires paid subscription from day one
− Context window smaller than Claude
− Occasional hallucinations on factual content
− No real-time web access on base plan
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
+ Finds issues Grammarly misses — redundant phrases, passive overuse, vague wording
+ Consistency checker flags character name/timeline errors in long documents
− 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
