I’ve been using it to translate my own software from English to my native language. I don’t live in my home country anymore and I notice my own speech is a bit awkward at times. Also because I typically use the English terms for common words like saving or clipboard.
Either way, I found it’s very good for these purposes giving a much more natural use of language than Google translate and with great context awareness. I wouldn’t dare using it on a language I’m not fluent in though.
