# Brain: overview

> The central place where you tell the agent who it is, what it can do and what it's connected to.

**Brain** is the control center of your agent. Here you set what it's connected to, how it behaves, and what it knows about you and your work.

## What's inside the Brain

<CardGroup cols={2}>
  <Card title="Integrations" icon="plug" href="/en/brain/connectors">
    External services the agent is connected to: Gmail, Google Calendar, Slack, GitHub. The agent reads data from them and performs actions — replies to emails, creates events, posts to a channel.
  </Card>

  <Card title="Skills" icon="bolt" href="/en/brain/skills">
    Ready-made behaviour patterns for repeated tasks. Like «summarize each meeting» or «reply to inbound support emails using a template». Install from the library or create your own in chat.
  </Card>

  <Card title="Knowledge" icon="book" href="/en/brain/knowledge">
    Everything the agent knows about you and your work: your name, company, preferred tone of voice, and reference documents.
  </Card>

  <Card title="Memory" icon="brain" href="/en/brain/memory">
    What the agent remembered from conversations. Like «Alex prefers short summaries». Saved between sessions automatically.
  </Card>
</CardGroup>

## Recommended setup order

1. **Integrations** — connect the services you need
2. **Knowledge** — tell the agent who it is and who you are
3. **Skills** — add if you need specific logic
4. **Memory** — works automatically, no setup needed
