# Private knowledge

> Upload documents into a knowledge base, ask questions with citations, and generate summaries, FAQs, mind maps, and audio overviews.

A knowledge base is a set of documents you upload once and query from chat. Files are encrypted
before upload and processed inside the attested gateway. Answers cite the source passage; open a
citation to read the original text.
