Not quite the same thing, but I used an LLM to cobble together a HTML file that allows me to search for products on Coles, Woolies, Aldi and Amazon at the same time in the same window (via frames and a Firefox extension to get around some security settings).

Works a treat when planning our big shops for the week, and has already saved us hundreds of dollars since Jan.

On the upside, homelabs are going to have a glut of high capacity, barely used server hard drives to choose from then this AI/data centre bubble eventually bursts?
