Is GUESTPIX written in other languages?
Currently, GUESTPIX is written in English only; however, you can add a message for all guests in multiple languages on your welcome page.
For your non-English speaking guests, their phone won't automatically convert our website to their preferred language unless they have a browser translation installed. You could recommend they install this extension for a better guest experience as it will automatically translate the page for them and should always be available if downloaded.
Similarly, any guest can choose to leave a guestbook message in their preferred language and, where needed, you and your guests can use your own browser translation extension to read these.
