Chatbot – Comparison of platforms

With everyone raging to adopt chatbots in different use cases to aid better customer experience, one of the challenge from a technology is which framework to build the chatbot on? Ofcourse custom and building from scratch is always an option however it would help if the process of development could be bootstrapped with the help of a platform or a framework that comes with pre-built features. Here is my take on the various chatbot platforms that are available and I will try to keep as much as updated as possible.

Dimensions Amazon Lex Google DialogFlow IBM Watson Microsoft LUIS
Ease of Use Uses speech language support similar to NLU Create rich custom UI and communicate using RESTful services via webhooks

Can be mixed with angular frontend and that provides flexibility

Complex given it has to fit within the IBM stack of products/suites and standards. No single API and no service to manage the conversation Deployment as HTTP endpoints and ability to converse as JSON is super helpful.

Natural language support is good similar to the one in powerbi

Voice Integration with Alexa is good

Ability to use skillsets from Alexa and mange is super helpful.

Google Assistant / Home – not as good as alexa Blends with Alexa skills Lacks voice capabilities and is not as good as its peers
Documentation Basic Basic Basic Basic
Validation Lambda integration helps Cannot block matches to context from intent Comes with very minimal validation

Has personality insights which is kinda cool

Has minimal validation functions
Prebuilt  AWS interoperability and ability to scale with EC2 instances Has prebuilt entities similar to LUIS Prebuilt models Entities such as location, money, age, date-time
