# Supported languages and localization in Paver

Learn about the supported languages in IBM® Paver. You can ask questions in a supported language during an interactive chat session and receive a response in that language. Use the `/lang` slash command to set the language for the entire session.

Paver supports the following languages in the CLI and web UI:

- Brazilian Portuguese
- English
- French
- German
- Italian
- Japanese
- Korean
- Simplified Chinese
- Spanish
- Traditional Chinese

## Changing the language

You can change the language in two ways: let Paver adapt to your language for each request, or set the language for the whole session.

### Let Paver adapt automatically

Send a request in a supported language, such as Spanish or French. Paver recognizes the language and responds in that language. This change applies only to that request. If your next request is in a different language, Paver responds in that language instead.

### Set the language for a session

Use the `/lang` slash command to set a consistent language for the session. This setting applies to the interface and to Paver's default responses.
