I tried this interesting product called Quillpad. It lets you create and store documents in your mother tongue. It provides an user friendly interface that makes typing a joy. You can just type the way you speak and Quillpad gets it right. You don't have to use keys like ^, shift etc. unlike other transliteration tools.

Go ahead and and start expressing yourself in any of these languages - Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Nepali, Punjabi, Tamil and Telugu.
