Would a tool like this help you when reading?

I've been learning Japanese and I keep running into the same problem when I try to read real text.

Most of the time I end up using a translator, but translators just give you the final English meaning. They don't really help you understand why the sentence means that or how the kanji and grammar work.

For example, if I see a word with kanji I don't know, I usually have to look up:

– the meaning

– the reading

– the radicals

– grammar in the sentence

– sometimes the nuance of the phrase

So I had this idea for a tool where you could highlight Japanese text anywhere (websites, articles, etc.) and it would show:

• the translation

• breakdown of the kanji (radicals, readings, meaning)

• explanation of the grammar in the sentence

• why that translation works in context

Basically more like a language explanation tool rather than just a translator.

I'm curious — would something like this actually be useful for people learning Japanese? Or are there already tools that do this well that I'm missing?

Just trying to see if this is a dumb idea or if other learners run into the same problem.
