How it works

From first call to working system.

Small steps you can see and test — you decide at every stage.

Question → retrieve → answer, with sources
Question → retrieve → answer, with sourcesAnimated explainer
01

Collect the knowledge

Catalogues, manuals, policies and FAQs — cleaned and split into searchable pieces.

02

Index it

Each piece is turned into a vector and stored with its source, so similar meaning can be found fast.

03

Retrieve, then answer

For every question the system pulls the most relevant passages first, then the AI answers only from them.

04

Serve it anywhere

A FastAPI service your website, chat, ERP or agent can call — documented and deployed.
