Cakey Bot (and our web dashboard) both support over 10 different languages. The language can be changed per-server and will apply for every user in that server. You can change the server's language from our web dashboard. Currently supported languages are listed below:
(Marcel & MST2)
(Aleph & Oğuzhan)
We are adding more languages and you can contribute via our Github Repository located here. Once the majority of a language is completed (>80% translated) on Github it will be added as an officially supported language.
