Building a Personal RAG Chatbot in a Few Days: Learning by Engineering Recently, I built a small personal Retrieval-Augmented Generation (RAG) chatbot.

It was not a long research project.

It was not something I spent weeks architecting.

And it definitely was not built from years of prior AI engineering experience.

It was a compact engineering exercise built over a few days, mostly through reading, experimenting, and applying engineering fundamentals to a domain I had not worked in before.
