The short answer
Beltr is a desktop app that turns the songs you already own into karaoke, with AI that runs on your own computer, for $19.99 once. Singa is a subscription to a streaming karaoke catalog, at $9.99 a month or $89.99 a year, with a free tier capped at 3 songs a day. Choose Beltr if you want to own your setup, sing your own music and stop paying for it. Choose Singa if you’d rather stream a big ready-made catalog, with polished phone and TV apps, and don’t need your own files.
Pay once, or keep paying
A subscription bills whether you sing every weekend or twice a year. Singa renews at $9.99 a month or $89.99 a year for as long as you keep it. Subscription karaoke in general runs roughly $80 to $120 a year.
Beltr is $19.99 once, about two months of Singa at the monthly rate, and then it’s yours. Updates are included for life, one license covers 2 devices, there’s no account, and you get a full refund within 14 days if you change your mind. The pricing page lays out everything the one payment covers.
The free tiers work differently, and it’s worth being straight about that. Singa’s keeps going, at 3 songs a day. Beltr’s is 5 songs in total, with no card and no time limit, and after that it’s the one $19.99 payment.
What you give up with Beltr
No licensed catalog. Beltr has nothing to browse or search. A licensed library is what Singa sells, and it’s the biggest difference between the two. If a song isn’t in your own library, Beltr can’t make karaoke out of it until you buy the track.
You bring the music. Any MP3, FLAC, WAV or MP4 you own goes through separation, and CDG, MP3+G, .kar, .mid and Thai NCN karaoke files play as they are. A small or patchy collection gets much less out of Beltr.
AI separation, not a studio karaoke master. Beltr takes the vocal out of the original recording with on-device AI. On a well-recorded song the instrumental can sound very clean, but results vary with the mix, and you can leave a little of the singer in as a guide.
A computer does the work. Separation takes a minute or two per song the first time you add it: quicker on Apple Silicon, slower on an older PC with only a CPU. Beltr needs an Apple Silicon Mac on macOS 12 or later, a Windows 10 or 11 PC, or a Linux machine, and the installer is 700 MB to 1 GB because the whole AI engine ships inside. Singa has apps that run on phones and TVs on their own.
The songs you own, on your TV
The song you want is already there. Streaming catalogs only carry what’s licensed, and songs can be pulled when rights change. Beltr works from your own files, so if it’s in your library you can sing it, and nobody can take it out.
Your music stays with you. Beltr runs its AI on-device, so your audio never leaves your machine. There’s nothing to upload and no account to make.
The whole room joins in. Beltr puts your songs on the TV with the lyrics synced word by word, and a room code and QR code on screen. Guests scan it and their phones become remotes and mics, with nothing to install; the free Beltr Remote and Beltr Client apps are there if you want them.
Live pitch scoring puts each singer on a leaderboard, you can change the key up to 6 semitones either way, and music videos can play behind the lyrics. Afterwards, Reveal Reel turns your best take into a vertical clip, shared only when you choose. For the whole setup, from the TV to the mics, see the guide to home karaoke on your TV.
