TweetLytics is not a free service. Let’s start there. It is designed by a Chicago firm for brand and buzz tracking. They do offer a free trial before asking for $199 to $299 per month in a no contract service.
Their demo video shows the ability to split information and trending on gender, sentiment. You are able to monitor, analyze and then engage with their interface.
So you might ask why this review is so short? Because they have no screenshots of the interface (they had a slick video that was a great marketing piece) but nothing on the product itself.
I couldn’t create a trial account without credit card information and my ability to remember to come back and cancel in the 30 days before getting charged. I like the idea of having the free trial, but let it be free, no credit card and then close and hold my data if I choose not to continue. If I continue, unlock my data and parameters I established and let me roll on.
