The party singing game where AI listens to every word. Pick a song, grab the mic, and prove you actually know the lyrics.
How it works
No downloads. No accounts. Just open the link, grab your friends, and sing.
Browse the library and choose a hit everyone knows. The instrumental loads — no vocals, just the beat.
2 to 4 players. Enter names, pick your colors. One mic, one device — pass it around like a party.
Each player sings 2 lines, then rotates. The lyrics scroll on screen. The AI listens through the mic in real time.
Gemini's native audio AI judges every line. Right words earn points. Wrong words lose them. No mercy.
Features
Everything you need for a proper singing showdown, nothing you don't.
Gemini 3.1 Flash Live processes your voice natively — no transcription delay, no lag. It hears what you sing and scores instantly.
See scores update live as each player sings. Green for nailed it, red for fumbled. The scoreboard never lies.
Pop, rock, hip-hop, ballads. From The Weeknd to Queen. New songs added regularly. Request your favorites.
Perfect for couples night, friend groups, or family game night. Everyone takes turns, everyone gets judged.
No app to install. Open the link on any laptop, tablet, or phone with Chrome. Just allow mic access and go.
Track your longest correct streak, worst fumbles, and all-time win record. The receipts are always there.
Scoring
The scoring is transparent. No mystery. You either know the words or you don't.
Sing the line right and earn a point. Minor pronunciation differences are forgiven.
Get a word wrong and lose a point. Every word counts. No mumbling your way through.
Go silent or sing the completely wrong lyrics? That's minus two. The AI knows.
Ready?
