# Youka Docs

> Guides and reference for creating karaoke with the Youka web app, desktop app, CLI, API, and SDK

Youka turns any song into a karaoke video. This site covers every way to use it — point-and-click in the web app or desktop app, automated from the command line, or embedded in your own product via the API and SDK.

## What is Youka?

Youka separates the vocals from any audio file or URL, syncs the lyrics word-by-word, and renders a finished karaoke video you can edit, export, and share. The same pipeline is available in the browser, on the desktop, and over a public API.
