Why not just use Claude?

You can get Claude to score a call in an afternoon. We use it every day.

A standard a team trusts takes longer: written levels for every skill, reference calls rated by people, and quotes checked against the transcript. Big Sister keeps that standard, and your Claude can read it through our connector.
