Duolingo

Available in 188 countries on iOS and Android, Duolingo Max introduces two AI-native learning capabilitiesRoleplay and Video Callthat provide interactive spoken and written practice with AI characters in realistic conversational scenarios, addressing the gap between structured lesson completion and actual conversational fluency.

Roleplay allows learners to practice conversational skills by interacting with Duolingo's cast of characters in scenario-based exchanges: ordering food at a café, asking for directions at an airport, checking in at a hotel, or navigating other everyday language situations.

The GPT-4-powered system understands and responds to natural language input from the learner, creating a low-stakes practice environment for conversational vocabulary and phrasing that structured lessons alone cannot replicatebuilding the real-time language processing skills that formal exercises do not develop.

Video Call takes conversational practice to a higher level of realism: learners engage in live voice conversations with an AI character named Lily on topics ranging from recent lessons to open-ended discussion subjects of the learner's choosing.

After each call, Duolingo provides a full transcript of the conversation along with detailed feedback on responsesidentifying grammatical errors, suggesting more natural phrasing, and explaining why certain answers were more or less successful.

This combination of real-time practice and structured post-call analysis creates a feedback loop similar to working with a human tutor.

Duolingo's core language curriculumspanning 40+ languages with gamified lessons, streak tracking, and adaptive difficultyis fully included in the Max subscription alongside the AI features.
