Did you guys struggle with the same problem?

As an avid learner of Japanese, one of my greatest challenges at the intermediate level was practicing the vocabulary I found in my textbooks. I frequently searched online but struggled to find texts that used the words I had just learned. All I had were the example phrases and listening drills provided in my textbooks, which frustrated me because I was eager to learn more but I couldn’t find the resources to do so.

I am considering developing a platform where users can create flashcards and generate engaging short stories, real news articles, and possibly listening drills using the vocabulary they are studying. What are your thoughts on this idea? Would you use an application like this?
