Case Study

Karaoke Smash

Type any topic, pick a song, get instant AI-generated parody lyrics that actually scan and rhyme.

📋 Overview

Karaoke Smash was an AI-powered parody song generator. Give it any topic — "my cat keeps knocking things off tables," "the printer in our office," "Monday morning existential dread" — pick a popular song, and it generates custom parody lyrics that match the original's rhythm, syllable count, and rhyme scheme. The lyrics were designed to be singable, not just clever on paper.


💡 Context

Started as a game my girlfriend and I came up with — we'd challenge each other to make up parody lyrics on the spot during karaoke. Graf, Nino, and I turned it into a real product. We reached a positive CAC-to-LTV ratio and were about to scale it with influencer Joey Kalico when we engaged a lawyer, realized our understanding of copyright law was incomplete, and spent two months pitching to Sony, WMG, and others. They passed, and we decided to cut our losses and move on.
