RAG Systems

RAG Systems, which stands for Retrieval-Augmented Generation, are a special kind of AI system that gives smarter, more informed answers. They work by first searching through documents or stored knowledge to find the most useful facts. Then, the AI takes that information and writes a response in a way that’s easy to understand and tailored to the question.

This approach is great when accurate, fact-based answers are needed—like for help desks, learning tools, or company knowledge bases. Instead of only relying on what the AI "knows" from training, RAG systems bring in real-time information and combine it with natural language to give better results. They’re a step up from basic chatbots because they mix searching with smart writing.
