Which AI works best for learning foreign languages?

No single AI is best for every learner: a structured app such as Duolingo Max or Speak works well for daily practice, while a general assistant like ChatGPT, Claude or Gemini is better for open conversation and corrections. The right tool also depends on which language you are learning and which one you already speak.

• Duolingo Max adds AI features on top of Duolingo Super, including Video Call, a live conversation with the character Lily, who remembers earlier calls, and Roleplay with AI feedback. Video Call was offered for courses in English, Spanish, French, German, Italian and Portuguese, with Japanese and Korean first on iOS.
• Speak offers AI tutoring with real-time pronunciation feedback for English speakers learning Spanish, French, Korean, Japanese, Italian or Mandarin.
• Google Translate has a Practice feature, a limited beta in the Android and iOS apps in selected countries. English speakers can practise French, German, Portuguese or Spanish, and speakers of several other languages can practise English.
• ChatGPT, Claude and Gemini can explain grammar, correct your texts and role-play conversations in many languages. ChatGPT and Gemini also have voice modes, and Gemini Live supports more than 40 languages.

Combine both approaches: use Duolingo or Speak for your daily routine and vocabulary, and a general assistant for conversation. Ask it to correct your mistakes and explain them, and check grammar points against a textbook or teacher, because chatbots can make mistakes.
