I built Pinyin Knowledge Ball, a free browser tool for Mandarin beginners. Link: https://py.dadafan.top/?utm_sour... The basic flow is: type a pinyin sound like "ma", then open its tone paths into characters, words, examples and audio. I also added focused pages for tone practice and pronunciation contrasts. The problem I am trying to solve is narrow: pinyin tables are accurate, but beginners often remember tones better when the sound is tied to a real character and word. If you have two minutes, I would like feedback on three things: 1. Is the first screen clear enough? 2. Would you understand what to do without reading instructions? 3. For an education tool, would you rather land on the interactive search box or a guided lesson page?
