StemRoller is a web-based AI tool designed to separate music tracks into their individual components, known as stems. Using advanced machine learning models, it allows users to upload any song and isolate vocals, drums, bass, piano, and other instruments with a single click. This process, traditionally requiring professional studio software and expertise, is made accessible and instantaneous.

The tool is built for musicians, producers, DJs, and content creators who need clean audio stems for remixing, sampling, karaoke creation, or practice. It operates entirely in the browser, ensuring user privacy and convenience without the need for software installation. The core technology is based on open-source AI models like Demucs, which have been optimized for web deployment.

StemRoller emphasizes ease of use and speed, delivering separated tracks in minutes. While the free tier offers core functionality, it may have limitations on processing speed or file length compared to premium services. Its primary value lies in democratizing access to high-quality stem separation for creative and educational purposes.
