Probably the most beloved and frequently used auto-translate service on the web right now is Google Translate. Given the dominance of Google in general, it wasn’t a huge surprise when it overshot the popularity of Babelfish and became the number one source for translations. Especially since both the search engine and Chrome browser have built in translation features you can use.
But what about tools that expand on that program and make it easier to use Google Translate? There are several that have been created, though I would say these are the four best resources to turn to. Keep in mind that each one uses Google Translate, and so is only as reliable as the service. To date, no program has been created that is able to perfectly adapt language. But in the future…who knows?
