During bbarbeque, dinners, and night out with friends, a little karoake is something anyone can bond over. But what if some of your frieds don't know how to sing!?  We can all have a little fun together, and use AI to make any night enjoyable

This Karoake Roaster is a chaotic multiplayer web application, where everyone is singing and being graded by a brutal judge persona, Gemini 2.5 Flash, who reads our singing abilities in the form of personas.  It checks for pitch, tonality, rhythm, and stability, and it is critical with grading you!

A fun part is that Gemini uses your friends agianst you. Before the singing starts, anyone else will write an assumption of how well you perform. Gemini will use those assumptions and roast the singer with it. Everyone can see who wrote what!

And the personally to me, more funny part, is that your webcam will be activated, and everyone can see you sing in real time, making it so even you and your friends can play together far away from each other.
