At this point UXPressia is available in English only. However, you can still enter the data into your personas, journey maps and impact maps in any language you prefer, be it Hindi, Arabian or Chinese.
We do have the interface localization on our roadmap though! Currently, we are considering the following languages: Spanish, Russian and Dutch.
Make sure you are logged in with Trello, find the “Future” column and hit thumbs up under the language you want to be available in UXPressia. Languages with the largest number of likes will be the first ones we will translate UXPressia into. ;)
