# Settings

> What is in each settings tab, and the three preferences that are only documented here — theme, interface language, and time zone.

**Settings** is the account-wide panel: how the app looks, what language it speaks, what it tells you about, and everything to do with your account and billing.

## When to use it

Settings holds the things that are true for all of your agents. Anything that is true for *one* agent — its prompt, its model, its tools — is in [Agent Builder](/docs/build/agent-builder/) instead.

## Getting there

Open the account panel at the bottom of the left sidebar and choose **Settings**. The panel has a search box at the top: typing a word jumps straight to the section that carries it, which is faster than remembering which tab something is under.

## What is in each tab

| Tab | Sections | Documented in |
| --- | --- | --- |
| **Account** | Profile · Sign-in & Security · Plan · LLM Key · API Keys · Devices · Sign out · Delete account | [Security and permissions](/docs/account/security/), [Bring your own key](/docs/account/bring-your-own-key/), [Agent API](/docs/build/agent-api/) |
| **General** | Appearance · Language & Region · Notifications | This page, and [Notifications](/docs/work/inbox/) |
| **Features** | A preview list of feature switches | This page |
| **Billing** | Current plan · Payment · Usage credits · Invoices · Cancel | [Plans and usage](/docs/account/plans-and-usage/) |

## Appearance

**Theme** has three choices: Light, Dark, and System. System follows your operating system, including when it switches at sunset. The choice applies immediately and is remembered in that browser; a browser you have not set it in starts on Dark.

## Language and region

**Display language** switches the interface between English and Korean. The change is immediate — the app does not reload.

Two things the switch does not do:

- It does not change what your agents write. An agent answers in the language of the conversation, and its own language is part of its [identity](/docs/build/identity/).
- It does not translate content you or an agent created. Prompts, memories, artifacts, and messages stay in the language they were written in.

**Time zone** sets the zone used to display dates and times across the app.

<Aside type="note" title="A routine keeps its own time zone">
  When you create a [routine](/docs/automate/routines/), its schedule records the time
  zone of the device you created it on, and it keeps that zone afterwards.
  Changing the account time zone here changes how times are *displayed*; it does
  not move a routine that is already scheduled.
</Aside>

## Notifications

The third section of **General** decides which events reach you and whether they arrive as browser notifications. It has its own page: [Notifications](/docs/work/inbox/).

## Features

The **Features** tab is a preview of switches that are not connected yet. Toggling one does not save, and reopening Settings shows it back where it was. Nothing there turns a capability on or off today.

## Limits

- Theme is stored per browser. A new device starts on Dark until you choose.
- Interface language covers the console. The [documentation](/) is a separate site with its own language switch, in the footer.
- The time zone list covers a fixed set of zones rather than every zone in the world.
- The Features tab does not persist. Treat it as a preview, not a control.
