About Chrome extensions

Question

Google Chrome

Is it possible to create a Chrome extension that would allow you to link a text note to a specific word (term, abbreviation, title, etc.) and, if this word is present in the text on any other pages, automatically show this note next to it?

Answer 1

Perhaps dig towards Content Scripts.

Answer 2

Of course, there is nothing complicated. It’s only better to load data upon request, otherwise, depending on the amount of stored data, memory can be consumed. And the question arises about the storage format in localStorage.
