What is Duolingo?
Duolingo is the world's most popular language learning app, used by over 500 million people to learn 40+ languages. Its AI personalises lesson difficulty in real time, adapts to each learner's weak points and uses gamification to keep users coming back daily — making language learning genuinely fun and effective.
Duolingo is effective for building vocabulary, basic grammar and reading skills. Studies show 34 hours of Duolingo equals a university semester for some languages. It's not sufficient alone for fluency.
Yes — Duolingo's core app is completely free with ads and heart limits. Super Duolingo at $6.99/mo removes ads. Duolingo Max at $13.99/mo adds GPT-4 features.
Duolingo Max is the premium tier with GPT-4 integration — enabling roleplay conversations with AI characters and detailed explanations of why your answers are right or wrong.
It varies by language and goal. For basic conversational ability in a related language, 6-12 months of daily practice. Duolingo works best combined with immersion and conversation practice.
