Remove vocals from any song with AI. Get synced lyrics in 12+ international languages, karaoke tracks, stem separation, pitch control. Free to start. This is a fully built AI karaoke SaaS app — live on the Apple App Store, Google Play, Amazon Appstore and web — now available for acquisition at $150,000.
The business is monetized through Pro subscriptions (Apple StoreKit, Google Play Billing, PayPal and UPI), with payments live on every platform. Built on a lean PHP + JavaScript stack with AI processing via API, it's simple for a solo owner or small team to operate. A new owner can hit the ground running with ~500 registered users growing weekly, US trademark and copyright filings, and fixed costs of ~$140/month. All assets — including the domain, full codebase for all four platforms, store listings, IP filings and user base — are included in the sale, with founder transition support available.
Frontend: Vanilla JavaScript + HTML/CSS (PWA) — no framework lock-infast loadeasy for any developer to maintain. Shared component library for nav/session across pages. Backend: PHP with JSON file storage — single-file API+7
