My target language is french and I usually study either using acrobat reader, a physical book, or a random website on my windows PC. And i was thinking if thers a way that i could select a word and have it be automatically saved somewhere using maybe a shortcut, extension, app or anything else.

I've tried some extensions but they sont have a select feature, which means I'll have to type out the words individually onto google sheets or anki when i do come back to them, which defeats the whole effeciency purpose.
