Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Duolingo

  • Free tier includes ads and energy-based hearts system limiting daily practice without paying
  • Gamification focus may appeal to casual learners but lacks depth for serious language study beyond conversational basics
  • Limited to short, bite-sized lessons without extensive grammar explanations or cultural context

LearnWorlds

  • The $24 Starter plan charges $5 for every paid enrollment, so selling a cheap course can cost more in fees than the plan
  • Escaping the enrollment fee requires the $79 Pro Trainer plan
  • Active learners are capped monthly, at 1,000 on Starter and 2,000 on both Pro Trainer and Learning Center
  • The $249 Learning Center plan allows no more learners than the $79 plan, differing on admins and AI credits instead
  • Admin seats are rationed at 1, 5 and 25
  • AI credits are metered monthly at 300, 500 and 1,000
