The AI is great, it translates very accurately, at a very fast speed! I have only experienced one glitch in which it translated the same word twice in a row. It's an excellent product. As far as I know, there are no cons. However, if you're looking for a reliable and accurate translation tool, then you should definitely look into it! There are some cases where I need to translate from English to French or Spanish. This AI is extremely helpful in those situations because it's able to translate in less than 10 seconds!
