# Multilingual Capabilities

indigo.ai supports powerful multilingual capabilities to help you **engage users in their preferred language,** without any extra setup. Whether you're building a single-language virtual assistant or need advanced control over multiple languages, here's how our platform handles multilingual conversations.

## 🌏 Multilingual by Design

Our AI Agents are **multilingual by design**. Powered by state-of-the-art large language models (LLMs), they can:

* **Automatically detect the language** your user is speaking
* **Understand and respond** in that same language
* **Support over 120 languages**, out of the box.

While the AI Agent can understand and reply in multiple languages, **some static elements are not multilingual unless specifically configured**. These include:

* The **Welcome Message**
* Interface text in the **Web Chat widget**
* Static content created using **Text Blocks** in workflows.

To make these elements dynamic for an extra language, you will need a custom add-on.

## 🌐 Adding an Extra Language (Add-on)

We offer an **advanced multilingual add-on** for clients who want greater control over user experience in each supported language.

With this add-on, you can:

* **Customize static messages** (e.g., welcome messages, quick replies) based on the user’s detected language
* **Adapt tone, phrasing, and content** to match the local culture or your brand’s voice in each language
* **Ensure a consistent multilingual experience** from the moment the assistant loads, including the chat widget bubble, first message, and full interface.

**🆕 Streamlined Multilingual Management**

In June 2025, we released a powerful new feature that simplifies the management of multilingual assistants. It offers **greater control** and an **easier setup** for automatically translating static content and widget interface elements, helping you deliver a seamless experience in every supported language.

#### Example: Personalized Welcome Messages

Once the multilingual add-on is enabled, your virtual assistant can:

* Automatically detect the user’s language
* Display a customized welcome message and other static content in that language
* Maintain language consistency throughout the entire conversation.

{% hint style="info" %}
Activating this option incurs an extra cost for each additional language. [Contact us](/need-help/our-customer-success-team.md) to enable this for your virtual assistant.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.indigo.ai/getting-started/multilingual-capabilities.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
