Does POP work in my language?

Probably yes! POP works in pretty much all languages. Currently, POP works with 61 languages.

Please note that for the NLP feature we use Google's NLP API and Google's NLP is limited to only a handful of languages. Here is a list of Google's current languages: English, Spanish, Japanese, Chinese (simplified and traditional), French, German, Italian, Korean, Portuguese, and Russian

That said, we haven't seen any performance issues using POP for optimization if your language isn't included in Google's NLP API list.
