I think the closest thing would be concept mapping software or knowledgebase software like Obsidian. But that's more about storing concepts and not so much about learning concepts.

If that software existed, it would be incredible.

Obsidian has a spaced repetition community plugin that I use when I write documentation. I add a flashcard for everything that I want to learn.

So you just put #flashcards inline (or whatever you tell it to look for) at the bottom if your file.

And then:

This is a question::this is the answer. This is another question::this is another answer.

I run through my cards about 30 minutes before I start work. It works very well.
