The GroupApp platform interface is currently available in English only. That said, many communities already run fully in languages like Spanish, Portuguese, French, and Arabic.
Support for additional platform languages is planned and on the roadmap.
What you need to know:
You can build your community in any language
This includes courses, posts, events, newletters, library resources, and events
The only part that remains in English is the platform interface
This includes navigation, buttons, and system labels
The interface is kept simple and easy to use, even for non-English speakers
