About StemNook

StemNook is an online audio tool. Upload an MP3 or WAV to separate vocals and accompaniment with AI, then preview and download both tracks. Use the audio cutter to keep the section you need.

Vocal separation runs with cloud-hosted Demucs, while audio cutting runs in your browser. No model installation is required. Results depend on the source recording; dense arrangements, reverb and layered vocals can leave artifacts. Listen before downloading.
