Review verdictDuolingo suits casual and foundational learners looking for an engaging, habit-forming way to practice a new language or brush up on math and chess. It is less suited for advanced speakers who require unstructured conversational immersion or specialized business fluency.The leading choice for training and internal communications at scale. Creative marketing that needs cinematic style will use different tools.
