So-Yoru/Hack1 ? reverse-engineered prompt

Build me a full educational app prototype called EduSphere AI that helps a student study Math, Physics, and Chemistry with AI tutors. I want one main AI that greets the student when they log in, looks at past session notes, and suggests what to focus on today, plus one subject tutor for each subject that can ask questions, answer doubts in chat, track how the student is doing, and generate a session report at the end.

Make it multilingual with English, Hindi, and Telugu, and let the whole UI switch languages in real time. Use a simple single demo user named Sahil, no login system needed. It should work even without any API key or database by falling back to scripted AI behavior and in memory storage, but if possible wire it so a real AI and database can be enabled later.

Please make it feel polished, with a home screen, subject pages, quizzes, a profile page with reports and stats, and a friendly student focused design.
