What it does in their own words:
Tweeting in more than one language is now possible thanks to this new tool. Tweetlator.com adds multilanguage support for your tweets for free.
Essentially this application will translate your tweet to 8 different languages simultaneously including English, Spanish, German, Italian, French, Portuguese, Japanese and Chinese. More languages will be added soon.
You just have to write a tweet on your own language and Tweetlator will translate it automatically. Your original message will be tweeted along with a link to a site with your tweet translations.
You can also edit the translations, retweet them and share them on Facebook.
Tweetlator is a viral application, with user generated content that allows you to internationalize your tweets.
How it beats the competition:
Now your followers will understand your no matters their native language, and all that with only one tweet. No more spam-like tweets with the same message in different languages.
