Duolingo Max


Duolingo uses Chat GPT-4 from OpenAI to make learning with Duolingo even more powerful. 

Duolingo Max gives learners access to two new features and exercises: 'Explain My Answer' and 'Roleplay'. Both powered by Generative AI. 

'Explain My Answer' offers learners the chance to learn more about their response in a lesson. By tapping a button after certain exercise types, learners can enter a chat to get a simple explanation on why their answer was right or wrong, and ask for examples or further clarification.

'Roleplay' allows learners to practice real-world conversation skills with world characters in the app. For more see here.


About Duolingo & CIOL


Duolingo has an important public service mission over and above its hugely successful and popular learning app. It is committed to advancing pedagogy and testing, mapping to international standards and promoting multilingualism. CIOL’s Royal Charter objects include encouraging the effective study and practice of languages as part of building international understanding and appreciation of other countries and cultures. The organisation also promotes clear standards and frameworks for language learning and use, encouraging testing and qualifications as part of building the confidence and professional language skills of individual linguists, and the awareness of employers and government of the language skills in their workforces and wider communities.

Both Duolingo and CIOL are committed to encouraging and maintaining the diversity in the languages used and learnt around the world. Duolingo maintains a broad, free language learning offer for beginners and intermediate learners in a very wide range of languages, while CIOL tests in more than 30 languages each year. Given these complementary goals, the two organisations have agreed to a formal partnership to work together to advance these important themes for languages and linguists.

Duolingo’s exceptional breadth of languages, constant innovation and unparalleled reach to both new and established language learners, makes it an exciting and complementary partner for the Chartered Institute of Linguists and our mission to raise the interest in and appreciation of language learning.
