Botsify is the only chatbot solution which offers LiveChat with the users (beside the chatbot) using the Facebook Messenger App itself (See here: https://bit.ly/2DX3Kfx )
The best part about Botsify is it's the ability to link with several integrations namely.
1- Zapier (1000+ Apps)
3- Google Search
4- Google Sheet
6- Amazon Alexa
It's easy to use, and can easily be embedded on your website, and typically replace the expensive Intercom and Drift Chatbots with the lead collection as well as the page, behavior-based messaging.
It increases the conversion and provides beautiful analytics about the overall impact of the chatbot in the dashboard.
