Not that weird but I use it as a translator and to learn Spanish. It's better than Google Translate because I can specify the region (i.e: Spain vs Latin America) and the formality. I can also experiment with more colloquial phrases and idioms that don't have a direct translation, e.g: "It's raining cats and dogs"

It can be useful in explaining grammar and fixing mistakes, though it can sometimes falter.

I tend to double check some things against other translators if it's something important of if the output looks fishy.
