The HBO Harry Potter reboot in 2026 is a global cultural event, bringing together millions of fans. Duolingo, known for making language learning fun through pop culture, seizes this moment with Sorting Hat AI—an interactive experience that helps users choose a language based on their HBO viewing habits. Just like the Sorting Hat assigns Hogwarts houses, Sorting Hat AI "sorts" users into their perfect language by analyzing their favorite movies and shows. This magical, gamified approach to language learning more engaging, shareable, and seamlessly tied to entertainment.
