Duolingo is a language learning app that uses artificial intelligence to help you learn languages. Duolingo put a lot of emphasis on its AI features. They have implemented features like using natural language processing and machine learning to understand how users are learning and improving their skills. It also uses adaptive algorithms that can determine when the user is stuck in a certain part of the course and provide them with a new skill set at the right time.
The app has seen an exponential amount of growth in recent years due to its innovative features and affordable pricing plans. However, there are still some areas where they need to improve their AI capabilities, such as providing more content, improving user experience, and making it easy for teachers and parents to use every feature on the app.
