Duolingo has announced the launch of 148 new language courses created using generative AI technology. This expansion marks the largest in the platform’s history, doubling its current course offerings. The company claims that this development will benefit learners directly, thanks to the speed and quality improvements offered by AI.
However, the move to AI-powered content creation has sparked backlash from users who are concerned about the impact on contractors and the potential degradation of the app’s content quality. Duolingo co-founder Luis von Ahn emphasized the benefits of AI in an email to staff, stating that it will enable the company to scale its content creation more efficiently.
The new courses, primarily designed for beginner levels, include features like Stories to develop reading comprehension and DuoRadio to aid listening comprehension. More advanced content is planned for launch in coming months.
