Rest assured that there is no dark arts being practiced here. InboundWriter is simply a product designed to put key insights and well established best practices into the hands of writers and online marketers so they can be well informed during their content creation process. Our software does not modify content automatically or spin it in any way.
The first type of information we think is valuable is the results of our topic research engine (topic modelling) which looks at how other people are talking about your areas of interest and extracts keywords which may be helpful to create more engaging content. Secondly we try to keep you informed of what is being shared on social networks (Twitter at the moment) regarding your topics of interest. Lastly we have a pretty sophisticated strategy and coaching engine that lets you tell us what the goal for your content is so that InboundWriter can give you tips and advise on how to best meet your goals.
We believe that striking a balance between creativity and optimization is best done by people who create the content and having good technology and key information at the right time can make that happen.
As for whether humble pie should be served I invite you try it yourself (it's a freemium product after all) or take a look at http://www.inboundwriter.com/impact at some of our results.
