Conversition’s TweetFeel analyses Twitter sentiment

TweetFeel.com allows users to search for any word. Search results flow down the screen, and mentions of the search term are marked either green or red based on the sentiment of what is being said.

The site offers an overall percentage number to indicate whether the majority of results are positive or negative.

Conversition was launched earlier this year by former Ipsos executives Jean Davis and Tessie Ting, whose first offering was MatterMeter.com – a site where users can vote and debate on whether brands or products matter to them.
