Keyword research with smart search suggestions?

[TheDude]

I found a smart search suggestion plugin that looks amazing and thought I'd see if anyone has experience with it.  www.suggest.io looks like a great usability improvement and even helps to do keyword research with what your visitors are searching on your site.

I'm excited about it and feel like it is too good to be true.  Does anyone have experience with this plugin or something similar?

No experience with it, and their "blog" links to a twitter account with 4 posts in the last 2 years.
