We have asked that question to our users and here are some reasons they mentioned
It is open source 💚
The configuration is extremely open and flexible
The code is self-explanatory and easy to extend
E.D.D.I is channel independent, therefore can be used anywhere
The (NLP) parser is extremely cool
The framework is focused and does not pretend to be the magic bullet that solves it all
Great tech stack, when you want to build a chatbot product yourself
The Chatbot System - E.D.D.I (Enhanced Dialog Driven Intelligence), has been developed with the focus on the use in enterprise applications as well as the ease of connecting it to other resources (such as databases or other services).
This platform has been developed for over many years and completely restructured from scratch four times because of logical "dead ends" in the art of building chatbots - thus version 4.
