Not OP but I definitely sympathise with them. I don't know how practical it is to implement or how profitable it would be, but the problem I often have is this: * I have something I want to buy and have specific needs for it (height, color, shape, other properties) * I know that there's a good chance the website I'm on sells a product that meets those needs (or possibly several such that I'd want to choose from) * my criteria are more specific than the filters available on the site e.g. I want a specific length down to a few cm because I want the biggest thing that will fit in a fixed space * crucially for an AI use case: the information exists on the individual product pages. They all list dimensions and specifications. I just don't want to have to go through them all.

Example: find me all of the desks on IKEA that come in light coloured wood, are 55 inches wide, and rank them from deepest to shallowest. Oh, and make sure they're in stock at my nearest IKEA, or are delivering within the next week.
