ChhotuGoogle is a nice tool to search in Hindi and Tamil. The site is powered by Google’s custom search and offers a very unique way to search in these Indian languages.
I have already suggested Google’s Online onscreen keyboard for searching in Indian languages, but ChhotuGoogle works very differently from it. To search in Hindi and Tamil, just log-on the site and start typing in the Roman script. ChhotuGoogle will automatically convert this into Hindi or Tamil.
It supports Unicode characters and Kruti Dev 010 font.
A nice tool for searching. I hope that it will include other indic languages very soon.
Try ChhotuGoogle :)
