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

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
