Live rapport score

The rapport gauge gives you a live, 0–100 sense of how the conversation is landing — so you can course-correct before a call goes sideways.

What it measures#

The score updates every 30 seconds from six linguistic signals, all computed locally:

• Turn balance — are you both talking, or is one side dominating?
• Response latency — how quickly each side replies.
• Backchannel frequency — the "mm-hm"s and "right"s that show engagement.
• Question reciprocity — are questions flowing both ways?
• Lexical convergence — are you starting to use each other's words?
• Agreement signals — explicit alignment in the language.

On-device, no AI cost#

Rapport scoring is pure text analysis on your Mac. It makes no AI call, so it adds nothing to your cost. If the score drops sharply, Sussur can flag the inflection so you notice in the moment.
