Jibun Drill

This is a web app where AI automatically generates "Original Kanji Drills" with a child as the protagonist. Simply enter your name and favorite theme (dragon, space, dinosaur, etc.), and you can learn kanji through your own adventure story. Ten questions form one continuous story, so the "I want to know what happens next!" feeling keeps you moving forward. I created this because I wanted to change kanji learning from something you "have to do" into something you "want to do."
