Google has introduced Ajax Language API. This new API boasts two functions, language translation and language detection – which cover 13 languages and 29 translation pairs. With the AJAX Language API, you can translate and detect the language of blocks of text within a webpage using only Javascript. The language API is designed to be simple and easy to use to translate and detect languages on the fly when offline translations are not available. They plan on adding more exciting capabilities to the AJAX Language API in the future, so stay tuned.

I have been waiting for this Language API from Google Translator for a long long time. Now we are able to translate our web pages, paragraphs or even words into different languages in real time. The Language Detection function comes in very handy as well. How exciting is that!
