Your music, mixed live by the Alchemist.
Alchemist Music plays the songs on your phone, and its AI DJ mixes them as they play: matching tempo and key, splitting each song into drums, bass, vocals and the rest, and blending and mashing them into something new.

Splitting songs into parts
The demo songs come ready split, so you can hear stem blends and mashups here. Your own songs mix whole on this page, with EQ blends. In the app and the PC program, an AI model splits every song into drums, bass, vocals and the rest, on your phone or your graphics card, so the Alchemist can blend and mash them part by part.
What the disks and colors mean
The effect the Alchemist is using on a song shows as rings in the black of its record.
- Ripples moving outwardAn echo: the sound repeats and fades, like the rings.
- A wobbling ringA filter sweep, build or dip. It wobbles more the harder it works.
- Flickering dashesA beat repeat or stutter: a slice of the beat played again and again.
- Spiral arcsA brake, spin back or scratch on the record.
- A song's shapeThe strip under each record: each bar's loudness, lit once played. Faint lines are phrases, orange marks its drop, blue where the next blend starts. Tap it to move there.
- Part sliders lit in blueA part you set by hand. The Alchemist keeps it there and works around it.

How it works
Everything happens on your phone. No uploads, no account, no subscription to start.
It listens to your songs
Every song is measured: its beat, tempo, key, energy, phrases and where it drops, even when it changes key or tempo part-way.
It splits them into parts
An AI model on the phone separates each song into drums, bass, vocals and the rest, so they can be blended part by part.
The Alchemist mixes
It picks what comes next, lines the beats up, and blends or mashes it in on the phrase, telling you why at every step.
A DJ that never runs out of ideas
The Alchemist does it all by itself. You can take over whenever you like.
Real mashups
Vocals from one song over another's beat, its melody, bass or drums, matched in tempo and key, on the phrase.
Let it cook
Past Full mashups: beat repeats, echo throws, filter builds, scratches and backspins, a sound kit of its own, and samples all through the set.
Turntables
Every song in the mix spins on its own record. Put a hand on one to scratch, brake or backspin, and it drops straight back in time.
Ingredients
The Alchemist cuts its own samples from your songs (a vocal, a drum bar, a bass line) and drops them into the set. Keep the ones you love.
Event mode
Plan a set ahead, each hand-over yours or the Alchemist's, play it any time with as much room to improvise as you like, and record it to a file.
It learns your taste
A thumbs up or down, and its quick questions ("Want a big drop soon?"), steer every pick, mash and drop that follows.

Questions
Is it really free?
Yes. Everything the Alchemist does is free. The free version plays a short on-air line now and then during its mixes; Alchemist Music Premium, coming soon, has none.
Which phones does it work on?
Android 10 or newer. Splitting songs into parts works best on recent phones; on older ones the Alchemist still mixes, with simpler blends.
Does it upload my music?
No. Songs are measured and split on your phone, and never leave it. It only goes online when you ask it to, for example to download the stem splitter or a brain.
Do I need an AI model?
No. The Alchemist mixes well by its own rules. A brain is optional, and it can run on your phone, your computer, or a cloud service you choose.
Where does the music come from?
From your phone: the songs in its Music folder and any folders you add. Copy music into the Music folder and it shows up by itself.
Can I try it without installing anything?
Yes. The web player on this page is a lite version that runs in your browser: press Start to hear the Alchemist mix three demo songs, or add a few of your own. Your songs stay on your device. For splitting your own songs into parts, get the app or the PC program.
Is there a version for my computer?
Yes: Alchemist Music for PC is out for Windows. It plays your library, splits your songs on your graphics card and sends them to your phone, with turntables, more decks and the same Alchemist on the way. Download it for Windows.
