Sometimes we might encounter some words that we don't know while reading.
My goal is to right-click or highlight it and then add it to a library/list so that I can do a recap as a flashcard-like practice to improve my vocabulary.
I have been googling and trying different applications but not one really does the job
Some come with a native vocabulary list that I don't need or do not have a native dictionary feature.
Ideally, it will be a web-based as well as iOS application.
Good tool but prefer a cross-platform app
FYI iOS has this lookup feature built-in already. Simple select the word and choose "lookup" or "translate". It'll give you a pop up with definition/translation and more info.

May I offer you my most enthusiastic contrafibularities for your efforts to improve your vocabulary
Anki or memrise. Flashcards with spaced repetition for learning anything really.
Memrise is a good tool to learn a new language but does it come with a self-building vocabulary feature? I did try before this post. thanks
There are Chrome and Firefox extensions that do just that, try searching for "vocabulary" on their respective extensions / Chrome webstore pages.
