kumar240520/Udaan-A-smart-student-Tool — reverse-engineered prompt

Build me a simple web app called Udaan, a smart student tool that makes school life easier through small automations. Since there isn’t much existing documentation, keep it practical and easy to understand.

I want a clean one page website where a student can quickly see their study tasks, add reminders, write short notes, and track what they need to finish today. Make it feel friendly and motivating, not like a boring admin screen. It should work in the browser without any setup, so please keep it as a polished HTML page with CSS and JavaScript included if that makes sense.

Add sample content so I can see how it works, and make the layout usable on both phone and laptop. Focus on making the experience smooth, simple, and helpful for everyday students. If you need to make assumptions, choose the simplest option that still feels complete.
