Agentic RAG Chatbot

A local agent-driven RAG system that combines LLM capabilities with tool integrations to deliver accurate, contextual AI responses without relying on external APIs.

01the problem

What needed solving

Most RAG chatbots are black boxes running on third-party APIs — you can't see why an answer was produced, and sensitive content has to leave your infrastructure to get an answer at all.

02approach

How I built it

01

Built a 5-step reasoning pipeline where each stage is inspectable, so any answer can be traced back through retrieval and reasoning.

02

Ran the full stack locally with no external API dependency, keeping content on-premise.

03

Integrated tools so the agent could act on retrieved context rather than only summarising it.

03outcome

Where it landed

A fully local, auditable RAG assistant — the same architecture I now use as the foundation for client chatbot work where data residency or explainability matters.
