Stop Your AI From Lying. Build RAG.

Stop Your AI From Lying. Build RAG. Day 9 - No vector database. No API. Just Ollama and a JSON file. A few weeks ago, a colleague stopped me mid conversation. “You keep learning all this AI stuff,” she said. “But tell me - if I ask your chatbot what your favourite colour is, will it know?” I went quiet. I knew how to build a chatbot. I had built one. But her question exposed a gap I hadn’t fully thought through. The chatbot I built could talk. It could remember our conversation.
