Build a Free ESP32 AI Chatbot: Multi-Device Q&A for Students (Groq API)

This IoT project transforms an ESP32 into a local web server hosting a smart Q&A assistant. It is an excellent, cost-effective study tool for students—capable of answering complex questions, like defining physics concepts with examples, instantly. Because it runs as a local web UI on your Wi-Fi network, multiple devices like phones, tablets, and laptops can connect and use the AI simultaneously without any extra app installations. ​What You Will Learn: ​How to configure the ESP32 as an asynchronous web server using the Arduino IDE. ​How to generate and integrate a free Groq API key for high-speed AI processing. ​Building a responsive, dark-mode web UI for seamless chatting across multiple devices. ​Routing API calls to models like Qwen for accurate, student-friendly answers.
