Duolingo is the world's most popular language-learning app, with over 500 million users learning 40+ languages through short, gamified daily lessons. Its bite-sized approach — five-minute lessons, streaks, points and a famously persistent owl mascot — turns language learning into a daily habit, which is why it succeeds where heavier courses fail: people actually keep coming back.

Duolingo Max is the premium AI tier (built on GPT-4 technology) that adds two standout features. "Explain My Answer" lets you ask an AI why a response was right or wrong, giving the kind of personalized grammar feedback a human tutor provides.

Prevo helps you rehearse high-stakes interviews before they happen. You choose a path (visa interview, US citizenship, business or investor pitch, or job interview) and practise out loud with a voice AI that asks realistic questions.
