Home karaoke · party mode · any song you own
Beltr removes vocals with local AI, shows synced lyrics on your TV, and lets guests queue songs from their phones.
The problem
Most karaoke options force you into a fixed song catalog, a monthly subscription, or random YouTube videos with ads and uneven quality. Beltr is built for the way people actually host karaoke at home: your songs, your TV, your friends, your night.
Party mode
Five things that turn a laptop and a TV into a real karaoke setup your friends will actually use.
Put big, readable karaoke lyrics on the main screen so everyone can sing along, even from the couch.
Guests scan a QR code and control the party from their phones — no app store install, no logins.
Let everyone add songs and take turns without crowding the laptop. The next singer is always ready.
Score singers in real time for a game-night feel. Compete for the crown — or just laugh at the leaderboard.
Use your own music files instead of waiting for a catalog to have the song. If you own it, you can sing it.
Beltr lowers or removes the lead singer with on-device AI — no cloud upload, no per-song fees.
How it works
Install Beltr, point it at your music, and your living room is the stage.
Import songs from your own library — MP3, FLAC, or WAV. No streaming catalog to argue with.
Local AI separates vocals so you can lower or fully remove the lead singer on every track.
Use the full-screen display for clean, readable, synced lyrics. Plug into HDMI or cast wirelessly.
Guests scan the QR code, queue songs, and control playback from their phones. The host laptop stays untouched.
Use cases
If there's a TV, a laptop, and people who want to sing, Beltr fits the room.
Replace charades with a sing-off everyone — even the cousins — actually wants to play.
Give the birthday person the mic and the queue. Their songs, their night.
Christmas, New Year's, Thanksgiving — every long family hang gets better with a song queue.
Laptop, smart TV, group chat full of singers. Beltr is the cheapest setup that doesn't feel cheap.
Queue up the bride's anthems and let everyone take a turn. No bar tab required.
Roll out a TV or projector, run Beltr off your laptop, and the patio becomes the stage.
After the food coma, before the dishes — one karaoke round to seal the night.
The default plan when nobody wants to leave the couch but everyone still wants to do something.
