AI Course Assistant
Flagship
A local, AI-powered learning platform. Admins create courses and upload
documents; students chat with a course-aware assistant, auto-generate
summaries and quizzes, reveal answers, export to PDF and review history —
all running offline through a local LLM (LM Studio). No data leaves the machine.
- Course-aware chat over uploaded docs — chunk retrieval → local model as context
- Multilingual document summaries: English · Vietnamese · 繁體中文
- Auto quiz generator with click-to-reveal answers + DB caching by doc/lang/count
- PDF export, chat history in Taiwan time, MathJax formula rendering
- Admin dashboard with live course / document / quiz statistics
