# AI assistant

> Ask the in-store assistant a question from a chat surface at the till.

The **AI assistant** is a chat surface at the till: a conversation sidebar beside a
chat panel with the message history, suggested prompts and a prompt bar. On a narrow
viewport the columns stack.

## Using the assistant

* Start a **new conversation**, or select or delete an existing one.
* Send a prompt, or pick a **suggested prompt**.

Prompts are sent to the backend assistant (`POST /v1/assistant/chat`), which proxies
the Solya agent. If no backend is configured, or a reply fails or comes back empty,
the assistant falls back to an offline canned resolver so the till never shows a
dead or errored bubble.

<Note>
  This "Assistant" is the AI helper. It is separate from the **Seller** (Vendeur)
  screen, which is where the cashier picks the salesperson active at the till.
