Frengly does translation, but does it beat Babelfish?
Frengly's language detection is even cooler than Google's, for a couple of reasons. First, you don't have to select auto-detection from a language list, like you do in Google Translate. If it's automatic, why should it take an extra step?
Second, you don't have to select a target language from a menu. You can just click it, and the original text remains on screen. If you want another language, just click again.
Frengly doesn't do webpages, and doesn't have a bookmarklet. If that's the bulk of what you want to do, stick with Google for now. On the other hand, it does save a list of your translations. If you're looking for a translator to help you do homework or understand a few words in a book you're reading, look no further.
