In the Fall '16 product release, we upgraded the user interface for the Predictive Content (formerly Content Recommendations) application and also added Predictive Content for email.
Predictive Content is the place to nurture and engage your web visitors and email recipients with the most relevant content, powered by machine learning and predictive analytics to boost your content consumption, increase engagement rates and deliver more conversions at scale.
This doc explains how to access the new Predictive Content App.
NOTE: The Predictive Content App is a separately sold product by Marketo. It rolls out for existing Predictive Content App customers (and older RTP customers who had content recommendations) by mid-January 2017.
