Very well writen! I liked how you connected your ideas and wrote about your feelings. So many of my Japanese students make do with detailing what happened. 😊 - "I think I forgot to submit something on italki, so I’m feeling pretty down. Lately, I’ve really gotten into using AI to build little apps, and I love sharing what I’ve made." I made this change as the original lacked punctuation. Having two sentences makes it easier to read. - "...build little apps, and I love sharing what I’ve made. For instance, I created a calculator app that shows how many credits students need to take at my university..." Changing "make some app" to "build apps" sounds more natural for programming. ​Adding "calculation app" or "calculator app" fixes the missing article ("a calculation app"). - "By the way, I went to Ultra Japan 2026! It was incredible. I've wanted to go for a long time, and I finally got to see my favorite DJ's set." Adding the preposition "to" after "went" and fixing the possessive form ("DJ's set") while keeping your excited, conversational tone. Sounds like you had a great time! 👍👍
