For AI artists

Test your hook
before TikTok does.

Drop the whole song. Our jury finds the 30 seconds that hit, real listeners vote on it blind, and you post the winner as a music video made from your cover, the words on the beat.

The jury listens to every second.

No paid AI, no guessing: our own listening scores every possible 30 seconds of your song on what makes a hook, and pins the three best on the waveform.

  • It comes back: choruses repeat, the jury hears it
  • The opening: the first 3 seconds decide a swipe
  • Energy, a clear voice, no dead air
  • Drag anywhere and the score follows you

Battles

Two cuts. Blind. The crowd decides.

Not sure which part is the hook, or which version is the hit? Put both in a version test. Listeners hear A and B without knowing whose they are and vote. The winner goes live for everyone.

  • Version tests for two mixes or two cuts of one song
  • A weekly Cup of the 8 hottest hooks
  • A theme every week: the winner gets a Spotlight

Studio

See the line where people leave.

Every listen is measured to the second. Studio shows how many people stay, where they swipe away, and the exact lyric line that was playing when they did.

  • Retention curve for every hook
  • Plays, listeners, saves, follows, countries
  • Where listens come from: For you, Battles, search, Crates
The steepest fall is at 0:17, on “i tada sam shvatio”. Try a cut that starts after it, or test it against the chorus.
Spotlight

Pay for listens, not for views.

Put a hook in the Spotlight and it plays to new listeners in For you. You pay only when someone stays 10 seconds or more. If most people skip it, it pauses by itself and the rest comes back to you.

  • Every Spotlight card says so, and by whom
  • A report: who stayed, how many to the end
  • Paid with Vibes you earn on Vibnelo
