CDI is one of my favorite AI tools that I use in this day to time. It helps me with data analysis, decision making, predictive analytics etc. The interface can be improved but it's not bad at all! As far as cost goes - you get what u pay for. There are many free alternatives out there which have much better features than their paid counterparts so if price isn't an issue then go ahead with them first before considering paying more money later down the road.
