The Duolingo story

Luis von Ahn, a visionary from Guatemala, delivered a captivating public service announcement about his mission to provide equal access to education for all. He humorously clarified the geographical location of Guatemala, distinguishing it from Guantanamo, where prisoners are held. With wit, he likened Guatemala to "Mexico's Mexico" for the American audience, emphasizing the challenges of illegal immigration from poorer neighboring countries.

Growing up in a financially modest family in Guatemala, Luis recognized the stark disparity in educational opportunities. He viewed education as a means of perpetuating inequality rather than bridging social classes. The wealthy could afford quality education, ensuring their continued prosperity, while the less privileged struggled to acquire basic literacy skills, perpetuating their economic limitations.

Luis's life took a different turn due to the dedication of his single mother, who invested her limited resources in providing him with a top-tier education. This enabled him to pursue higher education in the United States, eventually earning a Ph.D. in computer science. Around a decade ago, his desire to address the issue of equal education access led him to take action.

At that time, Luis was a computer science professor at Carnegie Mellon University. He partnered with his Ph.D. student, Severin, to embark on a mission to democratize education access. They decided to start by teaching one subject, considering mathematics and computer science before settling on foreign languages, specifically English. Their choice was influenced by the vast number of people worldwide learning foreign languages, primarily English, and the potential for increased income associated with language proficiency.

To reach a large and diverse audience, Luis and his team recognized the potential of mobile phones, especially smartphones. Establishing schools worldwide proved economically unfeasible, but most people had access to smartphones, with the trend indicating increasing accessibility. Thus, the idea for Duolingo was born.

Duolingo employed a freemium model, allowing users to learn without charge, with occasional ads. Those who preferred an ad-free experience could subscribe, and this predominantly included users from wealthier countries. This model effectively created a form of wealth redistribution by having affluent subscribers fund education for those who couldn't afford it.

However, smartphones presented a significant challenge when it came to educational apps: the allure of highly addictive social media and mobile games. To ensure people not only had access to education but also wanted to learn, Duolingo incorporated psychological techniques borrowed from social media and mobile games. These strategies made the learning experience engaging and fun.

One of the most potent techniques was the concept of a "streak." Users received a counter measuring the consecutive days they used the app, motivating them to return daily to avoid resetting the streak. This simple but effective mechanism encouraged users to engage consistently.

Notifications were another key tool, sending reminders to study. Duolingo employed a sophisticated AI system to determine the timing and content of notifications, but, interestingly, the best time to send a notification was found to be 24 hours after the last app usage. It capitalized on the assumption that users were likely available at the same time they were the previous day.

Moreover, Duolingo adopted passive-aggressive notifications when users became inactive for seven days. Instead of spamming users, they received a message implying that reminders weren't working and would be halted. This indirect approach was remarkably effective, as users returned, perhaps driven by a sense of guilt or pressure from the app's animated owl mascot.

Luis also shared humorous memes and anecdotes about Duolingo's mascot, highlighting the app's presence in popular culture and its ability to keep users motivated.

Duolingo's success proved that education could be made engaging, even if it couldn't compete with the likes of social media. Learning offered meaning and a sense of accomplishment that scrolling through social media often lacked. This approach ensured that users were not only learning but also enjoying the process.

Luis expressed his hope for a future where educational apps could provide high-quality education via mobile phones for all subjects. He envisioned a world where screen time was associated with meaningful learning, ultimately bridging the educational gap between rich and poor.

In conclusion, Luis von Ahn's journey from a humble background in Guatemala to the creation of Duolingo showcases his commitment to providing equal access to education. By using psychological techniques borrowed from addictive apps, he managed to engage millions of users in language learning. His vision extends to revolutionizing education for all subjects, where learning becomes as enticing as scrolling through social media.
