# Agents

> The brain of every conversation

An **agent** is a configured combination of a prompt, an LLM, a voice/text
behavior, and any tools or knowledge it can draw on. Every call, chat message,
or WhatsApp reply is handled by one agent.

## Where agents live

Agents are created and configured through **ai-engine** (the brain — model,
prompt, tools) and then attached to a **channel** in comms-engine (voice, chat,
WhatsApp, SMS) so they can actually talk to someone. See
[Channels](/docs/features/channels/overview) for how that attachment works.
