Interactive demo

RAG knowledge assistant.

Beginner prototype

This demo makes the RAG idea visible without overstating the build. It searches a tiny local knowledge base, ranks matching snippets, and drafts an answer from those sources. It does not use a real LLM, embeddings model, or vector database yet.

Local RAG-style demo

Ask the tiny knowledge base.

This is a beginner prototype: it retrieves matching snippets from local data, shows the sources, and drafts a grounded answer. No external model, API key, embeddings service, or production vector database is connected.

Draft answer

Keyword retrieval prototype

Based on the retrieved source snippets: Retrieval-Augmented Generation starts with a user question, retrieves relevant knowledge snippets, and passes those snippets into an answer step so the response stays tied to available context. A related retrieved note says: A useful RAG interface should show what information was retrieved. Visible sources make it easier to inspect the answer and notice when the assistant is missing context. This is a basic RAG-style flow because the answer is built from retrieved context instead of pretending to know everything.

AI learning path

A stronger RAG version would add document upload, chunking, embeddings, vector search, a server-side LLM call, citations, and evaluation checks for answer quality.
