Linva turns the language you want to learn into something you live in. Type or paste any text and Linva instantly translates it and voices it with natural, native-quality audio — a ready-made bilingual lesson in seconds. Read along sentence by sentence with the target language, your own language and IPA phonetics aligned together. Switch to immersive reading, or shadow the audio while a real-time pitch waveform shows how closely you match a native speaker. When you finish, get a pronunciation score down to the word and the individual sound, so you know exactly what to improve. WHAT YOU CAN DO • Generate a lesson from any text with AI translation + text-to-speech • Import your own audio — or a video — and Linva transcribes and translates it • Read bilingual text with synced audio and phonetics; tap any word for its in-context meaning • Shadow with a live waveform and loop any sentence • Score your pronunciation at the word and phoneme level • Dictation practice: hear the audio or see your language, then write the target word by word — streaks, sparks and sound effects keep you hooked • Watch videos and study perfectly synced subtitles • Chat with an AI to actually use what you just learned • Take a placement test to find your level • Keep a library of recordings, track your progress, and listen in the background even when locked Linva is built on comprehensible input: you acquire a language fastest by understanding real content slightly above your level — listening, reading and speaking until it becomes natural. Available on iPhone, iPad and Mac, with the interface in Chinese, English, Japanese, Korean, French and Spanish. Start your immersion today.
