About
Splitter.ai is a widely-used AI audio processing service that leverages machine learning to deconstruct music tracks into isolated components — commonly known as stem separation. Powered by Deezer's open-source Spleeter model, Splitter.ai makes it easy for musicians, producers, podcasters, and content creators to extract vocals, instruments, and other audio elements from virtually any song. The free tier allows users to upload audio files and perform basic stem separation, making the tool accessible to hobbyists and casual users. The PRO plan unlocks near-perfect 2-stem separation, reverb removal, direct YouTube URL splitting, and higher-quality output — ideal for professional use cases. Splitter.ai also offers an API for developers looking to integrate audio separation capabilities into their own applications or workflows. The platform is used by millions of people globally, spanning independent artists remixing tracks, karaoke creators removing vocals, music educators analyzing compositions, and developers building music-tech products. Key use cases include creating instrumental versions of songs, extracting vocal acapellas, removing reverb from recordings, and analyzing individual instrument tracks. The intuitive web interface requires no technical knowledge, while the developer API enables programmatic access at scale. With its combination of a generous free tier, a powerful PRO plan, and a robust API, Splitter.ai positions itself as a go-to solution for AI-driven audio stem separation.
