How it works怎么用
Pick a topic and a “student” — a curious child, a peer, or an expert. Then teach it out loud (by voice) or by text. As you explain, the AI plays that student and asks Socratic follow-up questions that surface the parts you glossed over. When you're done, it scores your fluency and subject mastery, and saves the session so you can watch yourself improve.先选一个题目，再选一个「学生」：好奇的小孩、同班同学，或者一位专家。然后用说的把它讲出来（语音），或者打字。你讲的时候，AI 就扮演那个学生，一句接一句地追问你含糊带过的地方。讲完它会给你两个分数：表达的流畅度和知识的掌握度，并把这次记录存下来，让你看得见自己的变化。
What's inside里面有什么
Teach by voice or text说着讲，或者打字讲
Speak naturally — it transcribes — or just type. Whatever helps you think.自然地说出来，它会转成文字；不想开口就打字。哪种能帮你想清楚就用哪种。
Socratic questioning苏格拉底式追问
The AI probes exactly where your explanation is fuzzy, like a good tutor would.你哪里讲得含糊，它就正好问那里 —— 像一个好老师那样。
Fluency + mastery score流畅度 + 掌握度评分
Two-dimensional feedback, plus a history so you can track progress over time.两个维度的反馈，还有历史记录，能看出自己有没有在进步。
Reads your notes能读你的笔记
Upload a photo of your notes or textbook and teach straight from them.拍一张笔记或者课本的照片传上去，直接照着它讲。
Who it's for适合谁
Students revising for exams, anyone learning something new, and curious people who want to really understand — not just re-read. Built by a high-school student who was tired of “I read it but can't explain it.”在复习考试的学生、正在学新东西的人，还有那些想真的搞懂、而不只是「又看了一遍」的人。做这个工具的是一个高中生，因为受够了「我看过了，但我讲不出来」。
