SplitSong

SplitSong is a browser-based tool that uses AI to separate a song into its individual instrument and vocal tracks. Users either upload an audio file directly or paste a YouTube link, and the tool processes the audio to isolate four stems: drums, vocals, bass, and a combined instrumental track covering keyboards and guitars. Each isolated stem can then be downloaded as a separate audio file. The tool is built for musicians, producers, DJs, and audio enthusiasts who want isolated tracks for remixing a song, practicing an instrument part in isolation, sampling, or simply studying how a recording is arranged. Because it accepts a YouTube link directly, it removes the extra step of downloading and converting audio before separation, which is a common friction point with other stem-splitting tools. SplitSong appears to be a small, independently run project rather than a company-backed product; the site credits a single creator by their social media handle and runs on Linode infrastructure in the US Southeast. No pricing, API, or third-party integrations beyond YouTube import are described on the site. As with most automated stem separation, one limitation is that isolation quality can vary by song, with some bleed between tracks depending on the original mix's complexity.
