With so many Facebook Messenger tools, how do you choose?

In order to figure out tool is right for you, consider two things: how you're going to use the chatbot for, and your coding savy.

How will you use the chatbot?

Some businesses want natural language processing and machine-learning chatbots -- if that's your goal, you'll want to select a platform that supports these features.

Keep in mind that creating chatbots like this take time and expertise.

If you're looking for more of a customer support platform or marketing tool, you can be up and running within just a few minutes using a platform like MobileMonkey.

How are your coding skills?

If you're not a developer, don't worry.

Many of today's chatbot builders are code-free, allowing you to drag and drop sequences and deploy your chatbot with ease.

Keep in mind that you may want to test several Facebook Messenger chatbot tools before making your final decision.

Many of the platforms listed above have a free plan (including MobileMonkey!) that will give you enough working knowledge of the tool to make an informed decision.
