Where sound meets intent

DJ your own music,
just by talking.

Tell Oto what the night should feel like. It builds a real DJ set from your own library—one you can steer in plain English.

01

Tell it about tonight.

Describe the mood, like you would to a friend behind the decks. Oto suggests tracks from your library, puts them in order, and explains why each one fits.

02

Change anything.

Move a track, change a transition, or ask for a different direction. Try ‘keep it mellow for two more tracks.’ You can undo any change.

03

Take the room.

Play it straight through, or perform: raise the energy, hold a moment longer than planned, and if you lose the thread, catch me brings it home gracefully.

Say what the room needs.

Oto turns plain language into an editable musical decision. You see what changed before the room hears it.

You

Hold this mood for two more tracks.

It learns you.
You stay you.

Oto learns from the tracks you choose and the changes you make. It offers suggestions, explains them, and leaves the final choice to you. Correct it when it gets your taste wrong. The more you play, the better it understands what sounds like you.

Your files, your stems, your taste model—local. Export everything in one click. Connected accounts share a taste signal, never audio.

Share a set with a friend. Oto adapts it to their music library and taste, and points out any missing tracks.

Learn what the room hears.

Seven interactive field guides turn DJ craft and audio technology into something you can hear, touch, and understand in your browser.

Do I need to know how to DJ?
No. That's the point. If you can describe a night, you can perform one.
Does it work with Spotify?
Oto performs music you own (files). Spotify connects as a taste signal—it helps Oto learn what you love, but streaming catalogs can't be mixed. You’ll need your own audio files to build and play a set.
Is the AI making the music?
No. It's your music, your order, your calls. Where Oto generates a few bars of connective tissue between two tracks, it's always marked—you'll see a 音 on it.
What happens to my data?
It stays on your machine. All of it. Export it anytime; it's yours.
