The company delivers courses in 40 languages through its flagship Duolingo app, with Spanish, English, French, German, Italian, Portuguese, Japanese, and Chinese among its most widely used offerings.

The platform attracts learners across diverse age groups and proficiency levels, from children to adults seeking professional language credentials.
