The Duolingo Paradox: How AI Led to $1B Revenue but Sparked a Mass User Exodus

Did Duolingo put its business success ahead of its learners? We dive into the massive controversy surrounding the language learning giant's AI-first business strategy. On one hand, Duolingo is crediting AI features like Explain My Answer and Birdbrain for a 51% user growth and a projected $1 billion in revenue, showcasing an unprecedented level of personalized learning. On the other hand, we explore the "shitstorm" that erupted after CEO Luis von Ahn's public announcement in April 2025.

And in a hybrid free-premium model, can financial success truly be separated from user satisfaction? Tune in to hear both sides of Duolingo's high-stakes AI experiment.
