Why this App

What it helps you achieve

Everyone knows their lines

Split any song by hand, evenly, or with AI that finds the real parts, like Angelica and Hamilton. Each singer sees their own lines highlighted.

Record anywhere, sing together

Each friend records on their own phone, whenever they like. Chorus lines every voice up with the music and plays them together.

Start from what others made

Reuse songs other singers already set up in Discover, or post the parts you still need on the casting board.

About
