Pros: First, a shout-out to the developers and especially the founder for taking lead in such an awesome product with great support. I've been with them solely for creating funnels on facebook messenger bot but ActiveChat wow me with more channels like telegram and the ability to integrate NLP easily! Drag-drop interface for creating skills/sequences with functions/fields is also improving. Impressed!
Pros: Having a woocommerce site than activechat is a must have bot for your facebook page. Not only for facebook they have bots for other platforms like telegram, and whatsapp bots are about to launch in a while. They have launched a website widget too. NLP is an addition to this bot its just more interactive than any other bot available. I am waiting for whatsapp integration
