Does it work in my country or language?
Yes. Competely reads competitor websites in over 50 languages, so it works for any country or region where your competitors publish their websites publicly. Supported languages include English, Spanish, French, German, Chinese (Simplified and Traditional), Arabic, Portuguese, Russian, Hindi, Japanese, Korean, Italian, Dutch, Turkish, Vietnamese, Polish, Hebrew, Thai, Swedish, Greek, and others.
The written analysis itself is produced in English. Some fields, such as the Tagline, keep the original language alongside an English translation in parentheses when the source isn't English, so the tone of the original line isn't lost.
How rich the analysis is depends on how much information each competitor publishes on the web. The language they publish in doesn't change that.
