Pros & Cons

Perusall

  • Genuinely free when using uploaded materials or open educational resources
  • Institutional Basic/Premium licenses eliminate per-student fees entirely for adopted materials
  • Courses set up before July 6, 2026 remain unaffected by the new pricing model
  • New courses at unlicensed institutions after July 6, 2026 can no longer offer a $0 Student Access Fee option
  • Instructors must now choose a $5-25 per-student platform fee for new courses without an institutional license
  • A real shift away from the previously free model specifically for unlicensed institution new-course setups

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
