Describe it.
HeySong builds it.
One sentence in. A structured, mixed and mastered track out — with lyrics, arrangement and stems you can actually release. No DAW required.
Free to start · 20 credits every month · No card required
moody late-night synthwave with gated drums, a warm analog bass and a yearning sax solo
A studio that behaves like an instrument
HeySong isn't a novelty generator. It's a production surface — with the controls, the exports and the licensing you need to put a track out today.
Structure, not noise
Every generation returns a real arrangement — intro, verse, chorus, bridge — with timings you can edit. Not a 30-second loop.
Vocals and lyrics
Write a brief and get sung, mixed vocals back — or force instrumental when you only need the bed.
Steer, don't gamble
Lock the tempo, the key, the length and the instrumentation. Regenerate a single section without losing the rest.
Release-ready masters
Export uncompressed WAV alongside a streaming-ready MP3, both mastered on our chain.
Seconds, not sessions
A first draft lands in your browser in under a minute. Iterate at the speed of thought.
From sentence to master in four moves
Each stage runs out of band, so you can close the tab. The job keeps going and the track is waiting when you come back.
Brief
Describe the track — genre, mood, instruments, tempo, and the story. Or paste lyrics and let the engine arrange them.

The raw take is levelled, glued and encoded to WAV + MP3. You get the structure map, the lyrics and the timings alongside.
