Dialogflow CX is an advanced Natural Language Understanding system from Google that allows building larger, more complicated, flow-based conversation models using an API or graphical web-based UI. These conversation models can be used via an API and offer business logic integration through developer-written fulfillment code. For the classic, simpler, non-graphical, and incompatible NLU from Google, see the dialogflow-es tag.
Dialogflow CX is a more advanced Natural Language Understanding system that is suitable for large or very complex conversational agents. Flows and pages are the building blocks of conversation design, and state handlers are used to control conversation paths.
Dialogflow CX consists of several components including
- An API that allows you to do conversational processing and get a response from a text or spoken phrase
- An API and graphical web-based UI that allows you to build the NLU and conversational model
- The ability to apply additional business logic through fulfillments
There is an older, less advanced, system that was formerly known as just "Dialogflow" (and, before that, "api.ai"). It is now known as Dialogflow ES. Questions about that version specifically should be tagged dialogflow-es.
