App that helps you learn words you encounter while reading

I've wanted to expand my vocabulary for a while, but I was tired of interrupting my reading sessions to google what words mean or write them down to come back to later (which I never do), and I'm too lazy to create my own deck of flashcards.

So I made an app that lets you input words you encounter (e.g. while reading, in conversation) and then quizzes you using example sentences generated from words you've saved. Still not sure if it is something people feel they want/need, but I've been using it quite a bit and a few of my friends have as well.

Would love to get thoughts from this sub!
