ManyChat helps you create Facebook Messenger bot easily for marketing, sales, and support. Their visual drag and drop bot builder helps you set up Facebook Messenger bot in a very short time. It provides you a set of tools to help you grow your Messenger audience. And it helps you broadcast your message effectively with Messenger. You can also automate your Messenger marketing.
Pros: The personal interaction with the team is probably the biggest draw for me. ActiveChat is one of the new players in the bot field, but they're clearly listening and responding to their early adopters via e-mail, the official Facebook Group and probably other channels as well. I am confident they will execute everything on their roadmap within a reasonable time frame, allowing us to create every type of bot we can imagine.
Cons: Botengine has reduced the workload on the helpdesk department . However ,I fear we may come one day have an advanced Botengine ,years down the line ; which is able to respond to the current complex queries we respond to and thus when that day comes , why would my employer keep me at the job ,when a Bot can do a better job ,without ever getting tired?
