RAG

What: Retrieve the nearest passages, then generate an answer that is allowed to use only those passages.
Why: A fluent model is not the same as a grounded one. Citations make the difference visible.
What you are seeing: Flow on the left lights as each step finishes. AWS Architecture on the right is that step’s box — click the title for the stacked twin. Click a finished step for passages or the grounded answer.

Static GitHub Pages demo — sample questions replay recorded runs with paced animations. Vector DB hashes in this tab and does not call localhost. Clone the repo and make dev for live labs.
