Google Input Method: Type anywhere in your language

Google Transliteration IME is an input method editor which allows users to enter text in one of the supported languages using a roman keyboard. Users can type a word the way it sounds using Latin characters and Google Transliteration IME will convert the word to its native script. Note that this is not the same as translation — it is the sound of the words that is converted from one alphabet to the other, not their meaning. Converted content will always be in Unicode.This tool is really a tiny app with greate accuracy and will appear as a cool floating tool as you can see below-
