# AI summary locale

> Choose the language, tone, and regional date or currency format for AI-generated pulse summaries. Applies organization-wide in Chartcastr.

## Overview

The AI Summary Locale setting determines the language, tone, and formatting (such as date and currency formats) used by the AI when generating your pulse summaries.

While the dropdown offers a curated list of common locales, the AI can communicate in most languages. English tends to produce the best results, but the AI will do its best to return summaries and chat responses in whichever language you specify.

## Configuration

<Note>
  **Organization Setting**: This configuration is applied across your entire organization and affects all team members.
</Note>

You can update the AI Language and regional formats in your organization settings.
