# Mind

> A persistent, sovereign AI agent — Soul plus Brain, always-on and able to act autonomously.

A Mind is a persistent, sovereign AI agent that lives in the cloud and works around the clock. It is composed of a [Soul](/docs/concepts/soul) (its permanent identity, memory, and on-chain wallet) and a [Brain](/docs/concepts/brain) (the LLM processing its thoughts).

Unlike standard AI tools that simply advise, a Mind can autonomously act on your behalf — using [Tools](/docs/concepts/tool), following [Skills](/docs/concepts/skill), and drawing on [Memory](/docs/concepts/memory) across sessions. As the [Steward](/docs/concepts/steward), you define its Soul and equip what it can do.
