How it works
Karaogle is an online 1v1: songs you know, lyrics on screen, and an impartial scoring system that decides who sings best.
Jump in and match
Hit Play, turn on your camera and mic, and we match you instantly with a random rival from anywhere in the world. No downloads, no waiting.
Listen and get ready
A clip of a song everyone knows starts playing. Read the synced lyrics on screen and catch the rhythm: you both sing the exact SAME part.
Sing turn by turn
First one sings, then the other, the same clip. Meanwhile you see each other live on video and your mic is recorded to score your performance.
The winner is decided
Both voices are analyzed, each dimension is scored from 0 to 100, and a winner is crowned with a commented result. Rematch or next rival: your call.

How it's scored

Pitch
Weight 40%Are you hitting the right notes? We measure the stability and accuracy of your pitch against the original melody. This carries the most weight.
Rhythm
Weight 30%Do you come in on time and keep the beat? We evaluate how well you fit the syllables into the song's rhythmic grid.
Lyrics
Weight 30%Do you get the lyrics right? What you sing is compared to the snippet's lyrics, word by word.
Final score = Pitch × 0.40 + Rhythm × 0.30 + Lyrics × 0.30. If the gap is tiny, it's called a tie.
