When you just copy the html, you get a ton of useless repeating data. This tool removed a lot of duplicated things, structures the styling in a better way where we don't spam the styling rules. The goal is to provide just the useful info, without the noise.

Having said that, it does do essentially what you described, but when prototyping fast, and not designing from scratch it's extremely useful.

Right, but that sounds like something any frontier LLM could one-shot. It’s a basic browser extension that wraps elements in the DOM and sends them to an LLM API embedded in a prompt. This would be neat as an open-source repo, but charging $10/month for this is certainly a choice.
