Duolingo, the language-learning application with the green owl, underwent a significant transformation in 2025, solidifying its position as a leader in digital education.
In the first quarter of 2025, Duolingo recorded a record increase in daily active users (DAU), exceeding 40 million, a 51% increase compared to the previous year. The number of paying subscribers also surpassed 10 million, contributing to a revenue growth of 38% year-on-year.
In April 2025, Duolingo launched 148 new language courses, doubling its existing offering. This expansion, made possible by the use of generative artificial intelligence, allowed these courses to be created and deployed in less than a year, a process that would previously have taken over 12 years.
Under the leadership of its CEO, Luis von Ahn, Duolingo adopted an "AI-first" strategy, integrating artificial intelligence into its development and operation processes. This approach not only improved the efficiency of content creation but also made it possible to offer more personalized learning experiences to users.
Despite these advances, the transition to an AI-focused strategy has sparked mixed reactions. Users have expressed concerns about the quality of content and the impact on employment, particularly due to the reduced use of contract workers in favor of automation.
In 2025, Duolingo demonstrated its ability to evolve and innovate, consolidating its position as a leading language learning platform, while navigating the challenges associated with the integration of artificial intelligence in the education sector.
