# Integrations Overview

> Every tool Indexbrain connects to, and how data flows in from each one.

Indexbrain extracts knowledge from the tools your company already uses. Each integration is documented as it's finished — connect, sync behavior, storage, and what to do if something doesn't show up where you expect it.
