Real shadowing, not just listen-and-repeat
Speak English with the rhythm of native speakers.
Open any YouTube video. We split it into phrases, you repeat them, and Shadowing scores your pitch, intonation, and accuracy — locally, in your browser.
Pitch & intonation
Compare your pitch contour to the speaker's using DTW. See where you flatten or rise wrong.
Privacy-first
Local Whisper.cpp transcription and pitch analysis run in your browser. Audio never leaves your device on the free plan.
Phoneme-level scoring (Premium)
Kaldi GOP scores each phoneme so you see which exact sound you missed — and how to fix it next time.
