# Using languages with AI Copilot

AI Copilot can work in multiple languages. You can either let Copilot detect the language automatically or ask your System Administrator to set a default language for your workspace.

### Supported languages

AI Copilot supports the following languages:

* English
* German
* French
* Spanish
* Italian
* Polish
* Portuguese
* Hindi

### Using a default language

Once your System Administrator sets a default language, it's applied to AI Copilot for all users and projects.

When a default language is set:

* Copilot always answers in that language, no matter which language you type in.
* This applies to chat, generating requirements, test cases, test data, and editing content.

✅ Example: If your default is **Italian**, Copilot will always respond in Italian, even if you ask something in English.

### When no language is set

If no default language is selected in system settings, Copilot automatically follows these rules:

#### Writing requirements or documents

* If you write in **German**, Copilot continues in German.
* If you write in **English**, Copilot continues in English.
* If you write in another language, Copilot uses the language defined in your aqua settings (either English or German).

#### Generating test cases

* Requirements in German → test cases in German.
* Requirements in English → test cases in English.
* Requirements in mixed languages → Copilot uses aqua settings.

#### Generating test case descriptions

* Test cases in German → descriptions in German.
* Test cases in English → descriptions in English.
* Mixed languages → Copilot uses aqua settings.

#### Editing or improving text

* English text → edited result in English.
* German text → edited result in German.
* If instruction and text are in different languages, the output matches the text language.
* Other languages → Copilot uses aqua settings.

#### Chat with Copilot

* Ask in English → answer in English.
* Ask in German → answer in German.
* Ask in another language → Copilot uses aqua settings.
