Beltr
Turn any song into karaoke with AI — no subscription, ever
Drop any song. AI strips the vocals in 30 seconds. Synced lyrics on your TV, phones as wireless remotes guests scan a QR code, no app needed. Real-time pitch scoring with leaderboards. 4-stem mixer lets you fade vocals for showtime or keep them for practice. Works with YOUR music library, runs fully offline, and costs $19.99 once no subscription ever. Try 5 songs free, no credit card.
Hey PH! I'm Jon, solo indie dev. I built Beltr because every karaoke app I tried was either subscription-based, required a specific song catalog, or couldn't work offline. I wanted to sing MY songs at house parties without paying $15/month forever.
The AI separation (Meta's Demucs v4) runs locally on your machine — your music never leaves your computer. Guests connect phones by scanning a QR code on the TV. No app download needed.
Launch price is $19.99 (normally $29.99) through April 15. Try 5 songs free, no credit card.
Would love your feedback — what would make this a must-have for your next party?
