Learn a language from what you love. Paste your own text, song lyrics or an article, have Zollang write one, share a YouTube link or just pick a topic: Zollang turns it into lessons you speak, listen to and read, built around your words. Learn English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Turkish, Japanese, Korean, Mandarin Chinese and Luxembourgish, with many more on the way. SPEAK — FROM DAY ONE • Speaking lessons: hear each sentence, then say it yourself. Can't speak right now? Switch to tap practice. • Conversation: talk out loud with an AI voice coach that knows your lessons and your vocabulary. • Practise your lesson: say your own lesson's sentences out loud. • Role play: everyday situations, out loud. • Pronunciation coach: get coached until it sounds right. LISTEN • Slow podcasts: two AI voices talk through an article or topic you choose, slowly enough to follow. Comprehension practice you can take anywhere. • YouTube lessons: learn from a video sentence by sentence, with color-coded translations. • Understand natives: hear how natives really say it. READ • Easy Reader: read your own texts and tap any word you don't know. • Sentence anatomy: watch a sentence being built, one step at a time. ONE VOCABULARY BEHIND IT ALL Every lesson feeds one personal vocabulary. Spaced review brings words back before you forget them, and contextual review puts them into new sentences. NOT SURE WHERE TO START? Begin with a pre-made lesson. MORE DETAILS A Speaking lesson starts with a new-word warm-up; an AI voice coach then builds each sentence chunk by chunk, and Explain clears up any phrase. A closing Recap rebuilds every sentence from memory. Then read it with audio and practice with flashcards, sentence building, fill in the blank, dictation, mix & match and shadowing. Free Conversation takes any topic you like. Practise your lesson gives you a hint when you're stuck. In Role play, pick a scene (Beginner or Intermediate) or describe your own: you get a role, a goal and phrases to use, for five minutes. The Pronunciation coach says a word, you repeat it, and it corrects you by voice. Slow podcasts come with a transcript, speed control and their vocabulary. YouTube lessons play the video with a synced transcript. Understand natives puts the textbook line next to the casual way natives say it. More ways in: scan a page with your camera, turn a word list into a vocabulary lesson with a story using every word, or read a long text in Easy Reader page by page, with word help and optional page audio (Quality or Basic voice). AI texts come in four levels: Beginner 1, Beginner 2, Intermediate and Advanced. Your words move from New to Learning, Reviewing and Mastered; rate each review Forgot, Hard, Good or Easy. Tricky words get extra practice. Save sentences with lists, tags and stars; browse verb conjugations and word lists. Track your study days, streak, words read and how many of the most common words you know. Pre-made lessons by topic and level need no credits. Teachers can share lessons with a class; students join with a code, nickname and PIN, no email. For travel, moving abroad, talking with a partner's family, work or school. One account on iPhone, iPad and the web, in English, Spanish, French, German and Brazilian Portuguese. SUBSCRIPTIONS Start free with a limited set of lessons and features. Starter and Plus subscriptions (monthly or annual) include monthly credits for creating lessons, audio and conversations; subscribers can also buy extra credits.
