How it works
Say a user is looking to buy a SmartPhone - a product with a lot of depth and many parameters:
Budget, OS, Size, Camera, Battery life, Special features (like water resistance, heart rate, etc), and much more.
An automated agent asks the user questions that help suggest the correct model, and where to buy it, and it works really well.
Example of niches where it is not effective
Think of VPN services, AntiVirus, website hosting - they are very narrow, essentially all the same feature-set and prices. A top 10 table with rating for each item serves better then a "personalization" technology in these cases.
