- **Console & REPL**: Interactive Python console with input() support
- **Offline PWA**: Works without internet after first load; installable as a native app
- **AI Assistant**: Experimental in-browser AI that explains code and translates tasks
- **QR code sharing**: Share programs via a QR code link — no login needed
- **Teacher mode**: Task panel with protection, student/teacher roles, and task description
