Create your own branded AI chatbot for WordPress powered by Google Dialogflow.

== Description ==

An artificial intelligent chatbot for WordPress powered by Google Dialogflow. [View Demo](https://danielpowney.com/my-chatbot-demo?utm_source=view-demo&utm_medium=free-plugin&utm_campaign=readme).

* Create your own branded chatbot
* Assume the appearance of a Dialogflow supported messaging platform to display rich message content. Currently supports quick replies and images, and displays these as messages to your website chatbot visitors.
* An overlay can be added on every page to display the chatbot. The overlay can toggle up or down.
* Shows conversation history across pages
* A shortcode and widget are available to display the chatbot.
* Add hyperlinks in response message content using HTML markup.
* Settings with color pickers for backgrounds and fonts, custom text (e.g. powered by) and opacity for old conversation bubbles.
* Lightweight and super fast as it uses the Dialogflow Agent API to process natural language queries.
* Enable the chatbot overlay to be displayed on specific posts.
* Secure. API authentication is server-side.
* In-built template system and plenty of extensible WordPress action hooks & filters.

**[my_chatbot] Shortcode**

Attributes:

 * debug - true or false. Default is false. If true, a textarea is added below the conversation area showing the Dialogflow JSON response data to assist debugging.

**Follow this plugin on [GitHub](https://github.com/danielpowney/my-chatbot)**

== Installation ==

1. Install and activate the plugin.
2. Create a Google Dialogflow agent. If you're a newbie I recommend you try importing the Small Talk prebuilt agent.
3. In the Google Cloud Platform console for your Dialogflow project, create a Google service account credential with DialogFlow API Client role permission. Download the credential key file in JSON format. Also enable the Dialogflow API.
4. Go to My Chatbot plugin options page under the Settings menu and configure key file settings.
5. Enabe the chatbot overlay or use the [my_chatbot] shortcode
