  • Can be overly prescriptive - Flags intentional grammar bends in creative writing or dialogue. Technical writers with domain jargon find it intrusive.
  • Expensive for individuals - $30/month for Pro (even at $12/month annually) is pricey for casual users. Free tier's 100 prompts run out quickly.
