About the course

Do you want to build a chatbot, so a bot that can talk? Yes, a bot that can talk to your friends or customers or fans while you sleep or do something else. You can make one for your customer that keep on asking the same questions. Or if you have a community for your fans and followers that want to know your details. Use your imagination, any time you have to reply the same thing over and over again, someone else like a bot can do it for you.

In the first part of the course, we'll make a chatbot without programming skills. We'll build a ChatBot that can answer frequently asked questions, and I'll show you how to teach your bot to have any other dialogs. We'll learn this by teaching our ChatBot to make job interviews.

We'll use DialogFlow to process natural language. DialogFlow will help the bot to understand what users want.

The chatbot will communicate to its customers via Facebook Messenger.

And in the second part, we'll use NodeJS to upgrade the bot. So the basic knowledge of javascript and NodeJS is needed.

With the new app, our bot will be able to remember things, that is, store information into a database or connect to other API services. With this, the bot will gain external knowledge and functionality.


At the end of the course, you'll have a fully functional ChatBot. And you'll also know how to teach the bot to have other dialogs with customers. You'll know how to make a bot for yourself and other people.
