AI karaoke video maker · for Windows

Every song,
ready to sing.

How it works

From song to sing‑along in four steps.

  1. 01

    Separate

    Bduo lifts the vocals out of the mix and keeps a clean backing track. Keep a quiet guide vocal if you like.

  2. 02

    Transcribe

    Every word is written down with its exact timing, and lines the AI imagined are filtered out. Fix anything in the review editor.

  3. 03

    Design

    Start from one of 25 looks, then tune motion, colours, artwork and lyric style. A six‑second preview shows the result first.

  4. 04

    Render

    Renders up to 4K on your graphics card, plus a title, description, tags and thumbnail ready to upload.

The studio

One window, start to finish.

Pick a look, check the lyrics settings and export. Every screen starts with sensible defaults, so most songs need only a couple of clicks.
