Your catalogues and rules. Read once, found by page.

Each folder says what the assistant does with it. Knowledge folders - catalogues, parts manuals, price lists - are read once and searched on every question, by part number and by word, and the answer names the file and the page. Pinned folders hold the few pages of rules that go into every answer. Everything else is simply kept, and opened only when someone asks about that file.

A module of its own: an admin turns it on, decides what the assistant reads, and decides whether the customers' robot may answer from a folder.
