Any successful virtual shopping assistant?

I'm sure someone has done this well, but I can't seem to find it on Google. I'd like a virtual agent to help me find the right items either on Amazon specifically or across online stores.

I'm specifically facing this issue with finding the right furniture. There's a specific type of cabinet I'd like with specific dimensions and looks. Searching across all furniture sites is a massive pain.

Does anyone know a good solution for this?
