# Assistant settings

> How one assistant behaves — its language, its default flow, and what it says when it cannot answer.

Configuration belonging to this assistant alone. Three tabs — **General**,
**Commands**, **Advanced** — and one **Save** covering all of them.

Not to be confused with the tenant-wide [Settings](/using/tenant-settings) in the
admin panel: those apply to every assistant at once.

## General

**Default language** — what this assistant answers in when the contact's own
language is unknown.

<Warning>
  It cannot be changed once flows exist. Content already written is treated as
  being in it, so switching later would mislabel rather than translate.
</Warning>

**Served countries** — which countries this assistant serves. This is not
cosmetic: it drives phone-number formats and validation in input nodes. An
assistant serving Ukraine validates a phone number differently from one serving
Poland, and a contact entering a valid local number should not be told it is
wrong.

**Default flow** — what runs when nothing else matches. Without one, a message
that triggers no flow produces nothing at all.

**Fallback message** — per language, what the contact hears when the assistant
cannot answer.

**Busy notice** — per language, sent when the assistant is still working on the
previous message. Leaving it empty is safe: a localised system text is used
instead.

<Note>
  The busy notice exists because a contact who sends two messages quickly would
  otherwise get silence while the first is still running. Silence reads as
  broken; a sentence reads as busy.
</Note>

## Commands

The built-in commands this assistant responds to — things like cancelling the
current session.

What those commands *say* is set in [Translations](/using/translations); this tab
is about which exist and how they behave.

## Advanced

The less-used settings, kept out of the way of everything above.

## Which settings live where

Three levels, and putting a value at the wrong one is the usual source of "I
changed it and nothing happened":

| Level         | Where                                            | Examples                                                   |
| ------------- | ------------------------------------------------ | ---------------------------------------------------------- |
| **Tenant**    | Admin panel → [Settings](/using/tenant-settings) | Available languages, runtime limits, broadcast pacing      |
| **Assistant** | Here                                             | Default language, served countries, default flow, fallback |
| **Flow**      | In the flow itself                               | What is actually said, and when                            |

A language must exist at tenant level before an assistant can default to it.
