TutoriaLLM is a self-hosted, full-stack web application designed as a programming learning platform for K-12 education. It features a Blockly-based visual programming interface integrated with Minecraft, AI-powered tutoring via OpenAI for real-time guidance and tutorial generation, and comprehensive session tracking including dialogue, workspace state, and multimedia. The architecture follows a monorepo structure with pnpm workspaces, separating concerns into frontend (React/Vite/Tailwind), backend (Node.js/Hono/PostgreSQL with Drizzle ORM), Blockly extensions, and documentation. Key functionalities include user authentication, session persistence, admin dashboard for content management, vector-based tutorial recommendations, and progress analytics. The system relies on external services like OpenAI API, PostgreSQL with pgvector, and S3-compatible storage (MinIO) for media.
