Pros & Cons

Lex

  • Genuinely simple pricing structure (free or one paid tier) compared to complex multi-tier competitors
  • Free tier’s 30 AI checks/month with multi-model access is usable for light writing needs
  • Pro plan includes a money-back guarantee for risk-free evaluation
  • Reported Pro pricing varies across sources ($14.99-$24.99/month) — verify the current rate directly
  • Free tier’s 30 AI checks/month may be limiting for heavier writing workflows
  • Premium AI models require upgrading to the Pro plan

AI Dungeon

  • Genuinely open-ended, with no fixed script limiting where a story can go
  • Can produce surprising and memorable creative moments
  • Large library of community-created scenarios to start from
  • Story coherence and quality vary significantly session to session
  • Requires active steering from the player to stay on track
  • Not a substitute for a polished, professionally written narrative game
