Moti316/studi — reverse-engineered prompt

Build me a Hebrew first study platform called StudiBuilder. It should feel polished on desktop and mobile, with full RTL support from the start.

The main flow is that a user signs in, lands on a simple dashboard, uploads source files like PDF, Word, or PowerPoint, and the app turns them into a gamified course. I want the course player to support three study modes, regular questions and answers, scenario practice, and an AI chat tutor. Include several quiz styles, progress tracking, XP and streaks, and Hebrew text to speech with a few voice options.

Please wire up the real backend pieces so users, courses, uploads, and generated content are saved properly, and make the course generation pipeline work end to end as far as the repo already supports. There should also be the beginnings of a product page flow for each course, with a landing page and basic purchase path if that is already planned here.

Use the existing docs and screenshots in the repo as the source of truth, and look up current docs online if needed.
