HP Chatbot AI

HP Chatbot AI is an immersive conversational product with eight distinct character personalities, dedicated voices and an intelligent source routing layer. I built it in roughly three weeks for an Applied LLM course.

01 · The problem

Why it exists

A character chatbot needs more than themed copy. It must retrieve grounded knowledge, keep personalities distinct, route questions intelligently and deliver a voice experience without losing conversational speed.

02 · Ownership

What I built

I conceived, designed and built the entire product. I also created its visual world and generated every visual used in the experience.

03 · System

How it works

FastAPI coordinates retrieval and conversation logic, FAISS supports grounded context, Qwen generates responses and ElevenLabs provides eight dedicated voices. The experience routes requests between character and knowledge sources.
