Sing along to anything playing in your browser.
Karafilt removes vocals from any tab in real time. YouTube, Spotify Web, SoundCloud, whatever's playing. No downloads, no uploads, just click and sing.
Works on Chrome, Edge, Brave, Arc, Vivaldi, Opera.
See it in action.
Play any tab, pick a mode, and click once — the lead vocal drops out in real time while the lyrics keep you on beat.
Three ways to strip vocals.
Every mode runs locally in your browser, in real time, and is free forever, so pick the balance of quality and speed you want.
| Mode | Quality | Latency |
|---|---|---|
| Spectral | Good | Real-time |
| Spectral Deep | Strong | Real-time |
| Basic | Fast | Real-time |
And sing every word.
Karafilt finds time-synced lyrics and highlights them line by line and word by word as the song plays, so you never lose your place.
