description Dialogflow Overview

Dialogflow, a Google product, offers a powerful NLP engine. While it has a visual interface, its true power lies in its API, allowing developers to build custom chatbot logic and integrate it with various platforms. It's a good choice for those wanting Google's NLP capabilities but needing more control than the visual builder provides. However, the free tier has limitations.

help Dialogflow FAQ

What is the difference between Dialogflow ES and Dialogflow CX?

Dialogflow ES is Google's older platform for smaller and simpler agents built around intents, while Dialogflow CX uses flows and pages for more structured conversations. Google's current pricing documentation lists ES Essentials text requests at $0.002 each and CX text requests at $0.007 each ([Google Cloud](https://docs.cloud.google.com/dialogflow/docs/editions?authuser=1)).

How do intents, entities, and fulfillment work in Dialogflow?

An intent represents what the user wants, while an entity extracts details such as a date, product name, or location from the message. Fulfillment calls a webhook or other service when the bot needs a dynamic answer, such as checking appointment availability ([Google Cloud](https://docs.cloud.google.com/dialogflow/es/docs/basics?authuser=2)).

Can Dialogflow connect a chatbot to a business database or API?

Yes. Fulfillment lets a matched intent call a service that you define, which can look up information or perform an action before returning the response. Google gives appointment availability as an example of data that a webhook can retrieve dynamically ([Google Cloud](https://docs.cloud.google.com/dialogflow/es/docs/basics?authuser=2)).
