Karafilt

About

Turn any tab into a karaoke machine. Karafilt removes vocals from the audio of the tab you're watching — YouTube, streaming sites, anywhere music plays — and shows time-synced lyrics in the side panel so you can sing along.

HOW IT WORKS
Click the Karafilt icon on a tab playing music — the side panel opens with the song's lyrics, pinned to that tab so the rest of your browsing is untouched. Press Start Filtering (or Ctrl+Shift+K) and the vocals drop out.

FEATURES
• Real-time vocal removal — no uploads, no waiting
• Two free filter modes that run entirely in your browser (WebAssembly): Spectral (frequency-selective, keeps bass and stereo) and Basic (fast center-channel cancellation)
• Synced lyrics with karaoke highlighting, from LRCLib (with Lyrics.ovh and Genius fallbacks) — including a focus mode that shows the current lines big
• Pick the right match when a song has multiple versions
• Vocal/instrumental mix slider — keep a hint of the original vocal as a guide
• Works on any site that plays audio

KARAFILT PRO (OPTIONAL)
The free modes are yours forever. Pro adds studio-grade AI separation (Demucs) running on our GPU servers for noticeably cleaner vocal removal — with a free trial. The extension is also self-hosting friendly: point it at your own server if you run the open-source backend.

PRIVACY
Free filtering happens 100% locally — your audio never leaves the browser. Song titles are sent to lyrics databases to find lyrics. Audio is only sent to a server in AI mode, to the server you choose, and is processed in memory — never stored. Karafilt is open source: https://github.com/lemara98/karafilt
