Premium Subscriptions

Duolingo’s premium subscription provides access to additional features and resources not available in the free version. The additional resources help users to learn language more efficiently and effectively. 

The personalized learning paths allow users to focus on areas of weakness and track progress on the app. Duolingo’s algorithm uses artificial intelligence (AI) to track a user’s learning style, identify problems, and offer personalized recommendations.

Duolingo has three premium subscription pricing tiers: Duolingo Plus, Duolingo Premium, and Duolingo Family. The Duolingo Plus provides an ad-free environment and an offline mode that allows users to download lessons for offline learning. 

The Duolingo Family is a family plan that enables five users to share a single account. Duolingo Premium offers additional features such as a progress quiz, which allows users to assess their progress on previously learned content.


Another strategy Duolingo utilizes to generate revenue is advertising within the app. Duolingo displays ads during lessons, which provides access to a broad audience. 

Its intuitive algorithm tracks user preferences and displays ads tailored to the user’s interests. The app’s advertisements generate revenue on a cost per click (CPC) basis, which means advertisers only pay when users click on the ad.

Additionally, Duolingo collaborates with advertisers to run integrated campaigns within the app. Its integrated campaigns are interactive and user-friendly, which increases engagement. 

By partnering with advertisers, Duolingo can generate additional revenue and expand its audience reach.

Fees from Events and Language Proficiency Tests

Duolingo holds language learning events worldwide that offer users practical ways to learn. Duolingo earns fees through these events and the sale of tickets, merchandise, and other products. 

The events feature language workshops, which enable attendees to connect with other language learners and network with experts in the field.

Duolingo offers language proficiency tests such as Duolingo English Test (DET), which allows users to take standardized English language tests online. 

Positive test results can serve as proof of language proficiency and be used for university admissions or visa applications. Duolingo earns revenue by charging a fee for these tests. The Duolingo English Test costs $49.

Selling Translation Data

Duolingo’s expansion into the translation services industry is a natural extension of its core mission of promoting language learning and cultural exchange. 

By leveraging the collective knowledge of millions of users, the app can offer improvements to translation quality that are more accurate, efficient, and cost-effective than competing solutions.

Duolingo’s algorithm uses many techniques to generate suggested translations and offer effective feedback. It builds on the massive amounts of data generated by users’ interactions in the app, both in terms of translations and the user’s language proficiency level. 

This data is then used to provide organizations with insights into the strengths and weaknesses of their translation workflows, as well as optimizations that can be made to the process to drive greater efficiencies.

Duolingo’s monetization of user data for translation services is a win-win situation for both parties. By selling translation data, Duolingo can generate revenue that further supports its language learning mission. 

At the same time, it allows organizations to tap into the nuanced and authentic knowledge representing real world usage of language that only Duolingo’s user community can provide.

Duolingo’s success in the translation industry is reinforced by its proven track record of innovation and success across all aspects of its business model. 

By providing comprehensive feedback and suggestions powered by the extensive knowledge of its user base, Duolingo’s translation services are an excellent example of how data-driven insights can drive success in today’s economy.
