Web Clipper - show if current url appears in any knowledge base and quick link to it.

While browsing, some indication in the web clipper that the currently browsed page appears in one or more of my knowledge bases, and have a link to reach it/them easily (maybe show a search result?).

I’m not sure how exactly to solve this one including all corner cases, urls can change on many websites, like youtube to include backend commands, and there’s user login issues... anyway, the simple cases of plain URLs cover 90% of linking, in my opinion (e.g. wikipedia).
