Agents can respond in any language. The user interface, or what the agent sees for buttons and instructions, etc. can be in English, German, French, Portuguese or Spanish.
It also might be valuable for you to know that we will auto-tag posts that have any of the following languages: English, German, Italian, Spanish, Portuguese, French, Dutch, Chinese, Tagalog, Korean and Japanese.
Additionally - you can have a look at this thread for detailed information: https://community.lithium.com/t5/Support-board/How-many-languages-are-supported-in-LSW/m-p/95418/hig...
Please, let us know if this is answering your question.
The LSW user interface itself (what the agent sees for buttons and instructions, etc) can currently be localized to English, German, French, Portuguese or Spanish. Other languages will have to be considered by the product team as part of the product roadmap. What other language(s) are you looking to support?
