Zollang turns your text, favorite songs, articles, into personalized language lessons. No generic drills. The material is whatever you actually want to read, listen to, or sing along with โ€” and Zollang builds the lesson around it. HOW IT WORKS 1. Paste any text, a song, article, or short passage in your target language. OR let Zollang AI generate the text for you from a simple prompt. 2. Zollang analyzes vocabulary, aligns translations word-by-word, and builds an audio-paced lesson. 3. Practice with an AI voice tutor that uses the exact vocabulary you just learned. 4. Review only what you don't already know โ€” spaced repetition handles the rest. WHY ZOLLANG IS DIFFERENT โ€ข Personalized, โ€” every lesson comes from content you chose. โ€ข Comprehensible input โ€” learn from material slightly above your level, the way linguists actually recommend. โ€ข Voice-first practice โ€” real-time conversations with an AI tutor that picks up where your lesson left off. โ€ข Honest spaced repetition โ€” mark words you already know and skip the busywork. โ€ข Color-coded sentence alignment โ€” see exactly how words map between your language and the one you're learning. LANGUAGES English, Spanish, French, German, Portuguese, Japanese, and Mandarin Chinese, Dutch, Russian, Turkish with more on the way. FOR WHO โ€ข Self-directed learners tired of cartoon-streak apps. โ€ข Intermediates stuck on a plateau who need real input, not more flashcards. โ€ข Anyone who learns best from things they actually care about.
