The most useful feature I have found so far is the ability to create custom models for my customers using their historical data from other platforms like Facebook or Twitter. It's very easy to implement and you can also use your own dataset as long as you know how to code Python and/or R! We were able to build our own model without any issues, but we still need some more time before we will be ready with all features implemented. This platform helps us understand our customer better by giving insights about them through several different ways - gender, age groups, interests etc.
