Was searching for CHATBOT everywhere but could not find something for WordPress. What I found everywhere was about FaceBook chatbots. After sometime I gave up. Again next day started working on ChatBot research and luckily found something cool on Codecanyon.net.
It suits the bill. Is only costing $31. And is a WordPress plugin.
All great features.
Now I just wanted to try the demo, which was also available.
And I tested it thoroughly. And I liked it.
Will be buying it asap.
