About

Shadow is how people actually learn to speak a language: by listening to a native speaker, saying it back, recording yourself and hearing the difference. Bring in anything you want to sound like β€” a YouTube video, a podcast, a voice note, a song, a scene from a movie. Shadow transcribes it, splits it into phrases you can repeat, and loops them until the words come out without thinking. ASK SHADOW β€” YOUR COACH, IN THE APP Stuck on how to say something? Ask in your own language and get the English a native would really use, with two or three ways to say it and what each one brings with it. Paste a sentence you wrote and see it rewritten the way people actually speak. Hear every answer in a British, American or Australian voice, see the phonetics under the words, and save the good ones straight into your practice. Then practice them. A ten-round daily session is built from your own saved phrases and the mistakes that keep coming back β€” answered out loud or typed, and marked one answer at a time with your own words next to the correction. SHADOWING, PROPERLY β€’ Phrase-by-phrase looping with the pauses you choose β€’ Record yourself over the original and compare, line by line β€’ Pitch and rhythm shown side by side, so you can hear what's different β€’ Phonetic transcription under any line β€’ Fold away an ad, a laugh or a line you'd never say, and the drill walks past it β€’ Save any phrase and drill it later, in collections you make MAKE YOUR OWN MATERIAL β€’ Turn any phrase into voiced examples in different situations β€’ Generate dialogues and monologues to shadow, in the accent and voice you pick β€’ Film yourself next to the original and export it BUILT FOR REAL LIFE β€’ Light and dark, following your phone or pinned to one β€’ Works offline once a clip is in β€’ Apple Watch remote for your phrase drills Whether you're preparing for a meeting, moving countries, or just tired of being understood but not sounding like yourself β€” Shadow is the practice that gets you there.
