Duolingo is the most downloaded education app in the history of the App Store. Our mission is to develop the best education in the world and make it universally available. Learning a new language is hard, but staying motivated is often the hardest part. That’s why we use fun, bite-sized, game-like lessons designed to keep you engaged and to drive real learning outcomes. Our approach is grounded in efficacy: we continuously test and improve our methods to ensure learners make meaningful progress. We also believe in democratizing education by offering an effective, high-quality free product. Developing a great free product is essential to our mission, ensuring that anyone with a smartphone can access learning that works. When it comes to utilizing AI tools, we have a golden rule: we use it when it clearly improves outcomes for learners. We don’t use it as a shortcut or a replacement for people, but as a tool to enhance learning experiences and efficacy. Duolingo has been named to: Fast Company’s Most Innovative Education Company (2026, 2022), Apple Design Award (2023), TIME100 Most Influential Companies (2023), Fast Company Best Workplaces for Innovators (2022), among others.
