RAGOfGold is a chatbot that answers questions about gold and silver prices. It uses blog data and a smart AI model to give answers based on real information.

🖥️ Client: HTML, CSS, JS

🛠️ Server: Node, Express, Socket.io

🧠 AI & NLP: OpenAI, LangChain

📄 Text Extraction: Cheerio, SanitizeHTML

• 🔎 Collects blog posts from a website
• 🧹 Cleans the content and breaks it into smaller parts
• 🧠 Converts those parts into embeddings using OpenAI
• 📦 Stores the data in memory for fast retrieval
• 💬 Searches for the most relevant chunks when a question is asked
• 🤖 Sends those chunks to the AI to generate an answer

This was my first time trying something like this. I followed helpful guides and examples from LangChain’s official docs, just learned and built it step by step.

The front-end uses a simple chat interface made with HTML, CSS, and Socket.IO so users can chat with the bot easily.
