# Brain

> Brain is Turnstone's durable local knowledge about you, your people, and your work.

**Brain** is Turnstone's durable local knowledge about you, your people, work,
history, preferences, and ongoing context.

## Use Brain

* Open **Brain** from the sidebar to browse or edit its knowledge directly.
* When Brain is attached to a turn, an Agent checks relevant areas before asking
  you to repeat information.
* As reliable new information emerges, the Agent can maintain the appropriate
  Brain records as part of the work.

Brain is separate from temporary files in an Agent's scratch folder. It is
local, editable, and organized into areas such as About You, People, Timeline,
and Work.

<Note>
  An Agent can use Brain only when the current turn reports it as available.
  Safe or isolated work may intentionally omit Brain access.
