Duolingo uses modern technology to teach languages in a way that is free, fun, and effective. Its mission: free language education for the world. Duolingo has three unique characteristics:
- It’s 100% free. All educational content is available for free for all.
- It feels like a game. Duolingo uses game elements so users have fun and stay motivated to learn. Learners earn experience points, work to unlock new levels, and more. Lessons are interactive (you must answer correctly to proceed) and are broken down into bite-sized exercises that can be learned on the go.
- Its methodology is rigorously science-based. Duolingo uses machine learning algorithms to understand how users are learning and generate personalized lessons accordingly — these algorithms use data points from users completing more than 7 billion exercises per month.
