Most language apps help you practice drills. LangTalk helps you speak. From your very first lesson, you are in a real conversation. The moment you slip, your AI teacher corrects you — and tells you why. That matters for learning fast. New subscribers start with a 7-day free trial. Full access to LangTalk requires a subscription. SPEAK FROM DAY ONE Talk or type with 40+ AI teachers, each with a specialty. Corrector Coach fixes your mistakes as you chat. Beginner Bilingual Guru gets you speaking from zero. Casual Carly makes you sound more casual to talk to friends. The Professor takes you past advanced. CORRECTIONS THAT ACTUALLY TEACH Say "yo soy emocionado" and you won't just get a red mark. You will learn that excitement is a temporary state, so it takes "estar" — with an example you will remember. LESSON QUESTS Learn inside an illustrated world that unlocks as you go. Greetings, family, numbers, weather, colors — each series ends in a roleplay you have to talk your way through. PRONUNCIATION, SOUND BY SOUND Type any phrase and hear a native say it. See it broken into syllables with phonetic spelling and IPA, pick your regional accent, then record yourself and get scored on accuracy and fluency. VOCABULARY THAT STICKS Save any phrase from any chat or lesson in one tap. Spaced repetition brings it back exactly when you are about to forget it — in Study, Quiz, or Type mode. TEN WAYS TO PRACTICE Trivia, Jeopardy, Matching, Mad Libs, 2 Truths & a Lie and more, all built from the words you personally have been learning. FIFTEEN MINUTES A DAY Today's Plan gives you a quest, a game and a flashcard set. Keep a streak, earn XP, and watch your LangScore climb. LANGUAGES Spanish, French, German, Italian, Japanese, and English for Spanish speakers. FREE TRIAL & SUBSCRIPTION AI teachers, lesson quests, roleplays, pronunciation coaching, practice games and flashcards are included with a LangTalk subscription, billed monthly or yearly. New subscribers get a 7-day free trial. Your subscription renews automatically unless you cancel at least 24 hours before the end of the current period; manage or cancel any time in your Apple ID settings.
