The Problem

Support teams drown in questions the docs already answer.

Most deflection tools hallucinate or refuse. This one retrieves, cites, and hands off when it's out of scope.

40–60%

Of support tickets are questions the public docs already answer.

2–5 min

A human re-types the same answer, every time.

Citations a hallucinating bot can give you. By definition.
