Pros & Cons

Grammarly

  • 2026 consolidation of Premium/Business into one Pro plan simplifies the pricing structure
  • Free tier includes genuine functionality (100 AI prompts/month), not just basic spell-check
  • Meaningful annual billing savings — $144/year versus $360/year if billed monthly
  • Free tier’s 100 AI prompts/month is a real constraint compared to Pro’s 2,000/member/month
  • Superhuman Business Bundle bundles in email features, which may not be needed by all writing-focused users
  • Enterprise pricing requires a custom quote for organizations needing unlimited prompts
