Duolingo Max adds GPT-4-powered features to the world's most popular language learning app. Roleplay lets you practice conversations in realistic scenarios - ordering at a restaurant, negotiating a price, or chatting with a roommate - with an AI that responds naturally and adapts to your proficiency level. Explain My Answer breaks down why you got a question right or wrong, providing grammar explanations and usage context that go beyond the standard "correct/incorrect" feedback. These AI features sit on top of Duolingo's proven gamified learning system, adding depth without changing the core experience. Duolingo Max is currently available for Spanish and French (from English), with more languages rolling out. The combination of Duolingo's engagement mechanics with AI-powered conversation practice creates a uniquely effective self-study tool for language learners.
