# AI

> The Custral assistant, chat agents, property auto-fill, and the tools that power them.

Custral's AI centers on an **assistant** you talk to in plain language. It reads your records, drafts and sends messages, and runs actions on your approval. Around it: **chat agents** (reusable personas), **property auto-fill** (AI that fills fields), and the **tools, rules, and connections** that extend what it can do.
