This was previously answered by Markus Danninger who said replient.ai automatically recognizes the language of the comment and gives you the three reply suggestions in the same language, so yes — it works in most languages (also Arabic). The dashboard is currently available in English and they’re working on more interface language support. You can find that answer here: https://appsumo.com/products/replientai/questions/languages-support-1359144/

And: What do you need to bear in mind when training Replient? Can this be done in different languages? Or are the responses given in the same language as the input?
