Languageshadow Ai Shadowi

LanguageShadow turns any YouTube™ video into active speaking practice. Pick a subtitle line, repeat it out loud, and get an AI pronunciation score on every word — built for learners who want to speak, not just watch.

How it works
1) Pick — Click any subtitle line on YouTube™ with the dual-subtitles overlay
2) Listen — Hear it in the original speaker's voice, at full speed
3) Repeat — Speak the line into your microphone
4) Score — AI grades your pronunciation against the line, phoneme by phoneme
5) Improve — Retry until it feels natural, or move to the next line
6) Track — See your accuracy across sessions in the side panel

Key features
• Dual subtitles on YouTube™ — your native language alongside the one you're learning
• Line-by-line shadowing — pause, replay, and repeat any caption with one click
• AI pronunciation scoring — phoneme-level feedback, not just a single accuracy number
• 33 languages and regional voices — English (US/UK/AU/CA/IN), Spanish (Spain/Mexico), French, German, Italian, Portuguese (Brazil/Portugal), Russian, Mandarin (CN/HK/TW), Japanese, Korean, Arabic (Egypt/Saudi), and more
• Side-panel progress — track which lines you've nailed and which to revisit
• Free for the core loop — 10 AI grades per day, with 3 grades before you sign in
