What We Do
StemSplitterAI is an online tool that separates songs into individual stems (vocals, drums, bass, and other instruments) using AI. Musicians, singers, teachers, and bands use it to create custom backing tracks, karaoke versions, drumless practice tracks, and isolated instrument stems from songs they already own.
How It Works
You upload an audio file, pick a task preset, and our AI processes the full song in minutes. You can listen to the separated result online before creating an account. The stem player lets you solo, mute, and adjust each part in the browser before downloading.
Technology
Our stem separation is powered by state-of-the-art AI models trained on large-scale music datasets. The processing runs in the cloud, so your device does not need special hardware or a fast GPU. Output is delivered in the format you choose before processing.
Pricing Philosophy
Buy Minute Packs when you only need a few songs, or choose an Unlimited Plan for regular processing with Priority Queue. Daily free minutes are used first and reset daily. Paid Minute Packs never expire, and partial minutes round up to the next full audio minute.
