Beyond the Chatbot: Engineering a Hybrid AI Math Tutor for the Future

Neural Math Lab is a React/Vite-based math tutoring app that hybridly switches between Azure OpenAI (with RAG from indexed textbooks) and local Ollama (DeepSeek-R1) for offline use. A Node.js security proxy enforces prompt injection filtering, safety categories, and strict mode while keeping API keys server-side. The system emphasizes privacy-first design with IndexedDB local storage and comprehensive user data controls.
