Duolingo Ramps AI Investment as User Count Soars

Duolingo, the world's leading mobile learning platform, is ramping up its investment in artificial intelligence (AI) as its user base continues to grow at an impressive rate. The company, which offers language learning courses through its popular app, has seen a surge in users and is now focusing on leveraging AI to enhance the learning experience and attract even more users.

In its latest earnings call, duolingo reported record revenue growth of 39% year-over-year for the fourth quarter, with daily active users increasing by 51% year-over-year to hit 40 million. The company attributed this growth to the strong adoption of Duolingo Max and the Family Plan, particularly during New Year promotions, and improved subscriber conversion strategies.

Duolingo is now leveraging generative AI to scale content and expand its offerings. The company plans to expand math and Music courses, which now have a combined 3 million daily active users. AI costs are mainly from features like Video Call in Duolingo Max, which adds marginal expenses but is expected to optimize over time. The company expects to expand its adjusted EBITDA margin to 27.5% in 2025, with a temporary 170 basis point impact on gross margin due to Max's adoption and AI costs.

Duolingo's AI expansion is not only driving user growth but also differentiating it from traditional competitors. The company's use of AI, particularly in its Duolingo Max tier, sets it apart from traditional language learning platforms like Rosetta Stone, Babbel, and Pimsleur. These competitors primarily offer structured, pre-recorded lessons, while Duolingo's AI-driven features like Video Call provide a more interactive and personalized learning experience.

Duolingo's AI-driven features, such as Duolingo Max, represent a potential revenue stream for the company. The company's pricing strategy for Duolingo Max is focused on ensuring profitability in various regions, allowing Duolingo to tap into a larger user base while maintaining margin expansion.



Duolingo's AI expansion has also enabled it to cater to a broader range of users, including those who prefer more interactive and engaging learning experiences. The AI-driven features, such as the Video Call, make learning a new language more fun and immersive, which can help attract and retain users who might otherwise be deterred by traditional learning methods.

In conclusion, Duolingo's increased investment in AI has driven user growth and differentiated it from traditional competitors. The company's AI-driven features, such as Duolingo Max, represent a potential revenue stream, and its pricing strategy allows it to tap into a larger user base while maintaining margin expansion. As Duolingo continues to invest in AI and improve the learning experience, it is well-positioned to capitalize on the growing demand for language learning and attract even more users.
