# Core Concepts

> Quick reference for the key building blocks of Waterr Meet.

A quick glossary of the key building blocks in Waterr Meet.

## Scenario

The complete conversation package -- a blueprint that combines who the AI is, how it behaves, and what it measures. Everything starts with creating a scenario.

## Persona

The AI character your participants interact with. Defines name, job title, demeanor, industry, background, and avatar. Participants see the name and avatar during the session.

## Meeting Script

The instructions that drive the AI's behavior -- how to open the conversation, what topics to cover, how to respond to specific situations, and the overall flow. Previously called "Instructions."

## Goals

Evaluation criteria the AI uses to score participants after a session. Each goal has a name, description, and scoring instructions. Goals are invisible to participants.

## Meeting Session

A single conversation instance. When a participant joins via a link, they start a meeting session. Each meeting session produces a real-time AI conversation (voice + optional video), a recording and transcript, goal scores and feedback, and speech analytics.

## Meeting Session Options

Settings that control how a meeting session behaves:

| Setting          | Description                                          |
| ---------------- | ---------------------------------------------------- |
| Duration         | Maximum session length (default: 35 minutes)         |
| Recording        | Whether the session is recorded                      |
| Consent          | Whether to show a consent prompt before starting     |
| Webhook URL      | POST results to your system when a session completes |
