Where each one falls short

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

Duolingo

  • Limited to short, bite-sized lessons without extensive grammar explanations or cultural context

Mode

  • Free tier limited to 4GB RAM and 1 CPU for SQL notebooks, insufficient for large datasets
  • Requires SQL knowledge for most analysis tasks, creating dependency on technical resources
  • Paid plan pricing not publicly listed; requires sales consultation
  • Recently acquired by ThoughtSpot in 2026, creating product direction uncertainty
  • Limited customization options for visual aspects and embedded analytics
