Duolingo Launches 148 New Language Courses Expands Access to Popular Languages Including Japanese and Korean
Duolingo has launched its largest content expansion ever with 148 new language courses, more than doubling its current offering. The expansion makes their seven most popular non-English languages - Spanish, French, German, Italian, Japanese, Korean, and Mandarin - available across all 28 supported user interface languages.
Through generative AI and automation, Duolingo completed this massive expansion in under a year, a process that previously took 12 years for the first 100 courses. The company's new "shared content" approach allows rapid customization of high-quality base courses for multiple languages.
The new courses focus on beginner levels (CEFR A1-A2) and include features like Stories and DuoRadio for reading and listening comprehension. The expansion significantly improves access for global learners, particularly in:
- Latin America: Spanish and Portuguese speakers gain access to Asian languages
- Europe: 15 language speakers can now learn Asian languages
- Asia: 11 languages gain access to all top seven languages

Insights
Duolingo's AI-powered expansion of 148 new courses demonstrates exceptional scaling capabilities, dramatically increasing market reach and operational efficiency.
Duolingo's announcement represents a breakthrough in AI-powered content creation with profound operational implications. What previously took "a small team years" to build a single course has been transformed into a process capable of creating 148 courses in less than one year - compared to taking 12 years for their first 100 courses.
The technology transformation comes from three key innovations explicitly mentioned in the release: generative AI, shared content systems, and internal tooling. Their "shared content" approach creates a high-quality base course that can be rapidly customized across dozens of languages, delivering unprecedented efficiency gains.
This represents one of the most tangible examples of generative AI creating real business value by dramatically accelerating speed-to-market while freeing human expertise to focus on quality assurance rather than content creation. This efficiency breakthrough enables the company to be significantly more responsive to market demands.
The expansion provides Duolingo substantial operating leverage - the ability to grow content library and addressable market at a far lower incremental cost than previously possible. This transformation of their content development pipeline demonstrates the potential for AI to create meaningful productivity improvements in knowledge work.
Duolingo's massive course expansion unlocks access to over a billion potential new learners, strategically targeting high-demand Asian languages globally.
This expansion represents Duolingo's most aggressive market penetration strategy to date, more than doubling their course catalog and dramatically expanding their total addressable market to "over a billion potential learners worldwide."
The strategic focus on making seven popular non-English languages available across all 28 supported user interfaces addresses a critical gap in global language education accessibility. Particularly significant is the expansion of Japanese, Korean, and Mandarin courses to regions where these increasingly valuable languages were previously unavailable through the platform.
The geographic targeting is precise and comprehensive: Latin American Spanish and Portuguese speakers gain access to Asian languages; fifteen European language speakers receive expanded options; and speakers of eleven Asian languages now have access to all seven top languages rather than just English.
The phased content rollout strategy - beginning with beginner levels (CEFR A1-A2) with advanced content coming in "coming months" - enables rapid market entry while building toward comprehensive offerings. The inclusion of immersive features like Stories and DuoRadio demonstrates attention to engagement and retention beyond basic language instruction.
This positions Duolingo to capitalize on growing global demand for Asian language proficiency while significantly expanding their serviceable markets across multiple continents.
PITTSBURGH, April 30, 2025 (GLOBE NEWSWIRE) -- Duolingo (NASDAQ: DUOL), the world’s leading mobile learning platform, today announced the launch of 148 new language courses, more than doubling its current offering and marking the largest expansion of content in the company’s history.
This launch makes Duolingo’s seven most popular non-English languages – Spanish, French, German, Italian, Japanese, Korean, and Mandarin – available to all 28 supported user interface (UI) languages, dramatically expanding learning options for over a billion potential learners worldwide.
“Developing our first 100 courses took about 12 years, and now, in about a year, we’re able to create and launch nearly 150 new courses. This is a great example of how generative AI can directly benefit our learners,” said Luis von Ahn, CEO and co-founder of Duolingo. “This launch reflects the incredible impact of our AI and automation investments, which have allowed us to scale at unprecedented speed and quality.”
Historically, building a single new course on Duolingo could take years. Through advances in generative AI, shared content systems, and internal tooling, the company created and launched this suite of 148 courses in less than a year. Duolingo’s new approach, known internally as “shared content,” enables the team to create a high-quality base course and quickly customize it for dozens of different languages.
“It used to take a small team years to build a single new course from scratch,” said Jessie Becker, Senior Director of Learning Design, Duolingo. “Now, by using generative AI to create and validate content, we’re able to focus our expertise where it’s most impactful, ensuring every course meets Duolingo’s rigorous quality standards.”
These new courses primarily support beginner levels (CEFR A1 – A2) and include immersive features such as Stories, to develop reading comprehension, and DuoRadio, to develop listening comprehension. More advanced content will roll out in coming months.
This expansion allows Duolingo to better serve global learners and meet the growing demand for learning popular Asian languages, like Japanese, Korean, and Mandarin. New course availability includes:
- Latin America: Spanish and Portuguese speakers can now learn Japanese, Korean, and Mandarin.
- Europe: Speakers of fifteen European languages like French, German, Italian, and Spanish can now learn Japanese, Korean, and Mandarin, among other top languages.
- Asia: Speakers of Japanese, Korean, Mandarin, Vietnamese, Indonesian, Thai, Tagalog, Hindi, Bengali, Telugu, and Tamil can now learn all of the top seven languages; previously many only had access to learning English.
