Shadow Master: Speak & Learn

Turn ANY YouTube video into a language lesson — pick a video, and karaoke-style captions guide you word-by-word while you shadow the speaker in real time. WHY SHADOWING WORKS Shadowing — listening and speaking along with a native speaker at the same time — is one of the fastest ways to build real speaking fluency, natural rhythm, and accent. Language coaches and polyglots have used it for decades. Shadow Master brings this proven technique to any video you already want to watch, instead of a fixed textbook curriculum. LEARN FROM ANY VIDEO, IN 40 LANGUAGES • Search YouTube directly in the app, or share/paste any video link to start a lesson instantly • Word-by-word karaoke captions highlight exactly where the speaker is, at their real pace • Adjustable playback speed slows fast speakers down without losing pitch • A caption-sync control lets you nudge the highlight earlier or later until it matches perfectly • Bookmark any video and pick up right where you left off • Auto-play countdown gives you a moment to get ready before each video starts • Supports 40 learning languages, with your native language set separately so every menu, hint, and explanation is in a language you understand ECHO SHADOWING Practice one line at a time: listen to the original sentence, record your own voice, then play both back to compare pacing, rhythm, and pronunciation. No pressure, no artificial scoring — just practice until it feels natural, the same way you'd rehearse with a coach. DICTATION MODE Sharpen your listening by typing exactly what you hear, then instantly check your answer against the real caption. Great for catching words your ear tends to miss. BUILD YOUR VOCABULARY Tap any word in a caption for an instant definition, translation, and native pronunciation. Save words you want to remember to My Deck, then review them with spaced-repetition flashcards that resurface each word right before you'd naturally forget it — so vocabulary actually sticks instead of fading after one video. STAY MOTIVATED, DAILY Daily missions and progress goals — videos shadowed, new words saved, cards reviewed — turn practice into a habit instead of a one-off. A fresh set of recommended videos is ready for you every day, picked from real content across the language you're learning. MADE FOR HOW YOU ACTUALLY LEARN Customize caption highlight colors, control auto-replay behavior, resume playback exactly where you paused, and fine-tune every setting around your own pace. There's no rigid lesson plan here — you choose the content, and Shadow Master handles the technique. Whether you're learning English, Spanish, Japanese, French, Korean, German, Chinese, or dozens of other languages, Shadow Master turns everyday YouTube watching into real, active speaking practice — one video, one sentence, one word at a time.
