StemKit splitting Bohemian Rhapsody into six stems
SOUND ON · CLICK

How it works

Three steps. No accounts, no uploads.

01

Paste a link, or search

YouTube search is built in. Find the song without opening a browser tab, hit split, and keep working while it runs in the background.

02

Pick your instruments

Standard four stems, or add guitar and piano. Only what you ask for gets produced, so the split finishes faster.

03

Play, mute, solo, export

All stems stay synced to the original video. Export any of them as WAV files that drop straight into your DAW.

Search

Embedded YouTube search.

Type a song, click the result, and the split starts in the background. You never open a browser tab.

  • Results appear while you type
  • One click sends it to split
  • No browser tab, ever

Split

Seamless stem splits by instrument.

Pick vocals, drums, bass, other, plus guitar and piano. The split runs locally with live progress, and presets isolate each instrument while the playhead keeps moving.

  • Vocals, drums, bass, other
  • Guitar and piano when you need them
  • Live progress, runs locally

  • Library remembers every split
  • Export any stem as WAV

Use cases

What you can do with the stems.

Learn your instrument
Solo the guitar, piano or bass on any song you are studying and play along. Mute everything else and the part you are learning stops being a guessing game. Rewind a hundred times, the app never gets tired.
Sing
Any track becomes your backing band. The karaoke preset strips the vocals instantly, at home, at a party, or for the cover you have been planning to post. No per-track fees, no waiting on a service.
Remix and sample
Pull acapellas and drum loops for flips and mashups. Export as WAV, drop them into your DAW, and get to work. It runs on your machine, so your ideas never touch someone else's server.
Study the mix
Hear what the drummer actually played. Isolate the bass line you could never pick out of the mix. Solo the piano part on your favorite record and learn the voicings by ear.
