Karafilt

Turn any tab into a karaoke machine — solo or with a whole room. Karafilt removes vocals from the audio of the tab you're watching — YouTube, Spotify, streaming sites, anywhere music plays — and shows time-synced lyrics so you can sing along, now word by word. New: Spotify support and word-level lyrics. Free. HOW IT WORKS Sign in with your free Karafilt account, then 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. PARTY MODE — karaoke with friends Click Party in the side panel and a host screen opens with a QR code. Your friends scan it on their phones (no account, no app), paste a YouTube link, and add songs to a shared, real-time queue. Songs play in order on your screen and auto-advance — vocals removed, with synced lyrics on the host screen and on every guest's phone. Everyone just takes turns and sings. FEATURES • Real-time vocal removal — runs entirely in your browser (WebAssembly), no uploads, no waiting • Party Mode — host a karaoke party: friends add YouTube songs to a shared queue from their phones via a QR code, and everyone sings in turns with synced lyrics • Three free filter modes: Spectral (frequency-selective, keeps bass and stereo), Spectral Deep (also strips center backing vocals for a cleaner karaoke mix), and Basic (fast center-channel cancellation) • Word-by-word lyrics — words light up one at a time as they're sung, not just line by line, powered by Karalyr (the open karaoke lyrics database), with LRCLib, Lyrics.ovh and Genius as fallbacks — including a focus mode that shows the current lines big • Works on Spotify's web player, YouTube, and any other site that plays audio • Instrumental countdown — during long breaks, a bar shows how long until the singing returns • Pick the right match when a song has multiple versions • Vocal/instrumental mix slider — keep a hint of the original vocal as a guide FREE, WITH AN ACCOUNT Karafilt is completely free. You sign in once with a free account; you can delete your account at any time from karafilt.com. Friends who join your party don't need an account. PRIVACY Vocal removal happens 100% locally — your audio never leaves the browser. Song titles are sent to lyrics databases to find lyrics. When you listen through a song that has no word-level timing yet, Karafilt sends that song's title, artist, link and the lyrics it already found to karalyr.com so it can be word-timed for everyone — no audio is ever sent. In Party Mode, the song links and display names you and your guests add are stored to run the shared queue.
