Add AI-powered dialog practice simulator

I've been studying Chinese for a while, and like many of you, my journey has been a mix of textbooks, videos, and apps. I often felt something was missing—a way to actively *use* the grammar and vocabulary in a flexible, interactive way, beyond just multiple-choice questions. So, I decided to build something to fix that. **What I'm Building:** It's a platform (not specifically a "Chinese learning app") that allows **teachers and content creators** to easily build interactive exercises. The goal is to add an interactive layer to their existing teaching methods. Think of it as a toolbox for teachers. They can create things like: * **Drag-and-Drop Sentence Builders:** To practice grammar and word order visually. * **Dynamic MCQ & Fill-in-the-Blank:** But more sophisticated than the basics. * **Third-Party exercise Extensions:** This is the cool part. The platform will support plugins, like a **dialog practice simulator** where you can have conversational practice with AI. **Why I'm Posting Here:** I'm not here to promote a finished product (it's still in development!). I'm here because this community has the exact people I built this for: 1. **Learners:** Does this sound useful to you? What kind of interactive exercises would make you say, "Wow, I finally get how to use this grammar point"? 2. **Tutors & Teachers:** Would a tool like this save you time or make your lessons more engaging? What's the biggest hassle in creating practice materials for your students? My thoughts are all over the place because I'm so deep into the code, and I wanted to get this out there to see if I'm on the right track. Studying Chinese made me realize we need better interactive tools. I'm building a platform for teachers to create custom exercises (sentence builders, MCQs, even AI dialog practice). Looking for your thoughts and what *you* would find most helpful. Thanks for reading! Any feedback is appreciated.
