Yes you can. Although Surveybot doesn't do language translation on it's own you have the ability to add all of the content for your Survey in the language that you prefer.

There are 2 places in which you'll need to do this.

From your Survey Design page when you add questions enter all of your questions using your chosen language. (see screenshot below)

Next you'll need to setup your default Survey messages. These include error messages for each question type as well as other default messages that are sent by your Surveybot. From the Survey Design tab go to Settings -> Advanced. (see screenshot below)
