In order to develop popular conversation apps, services and bots on the Messenger platform, it is necessary to understand the characteristics of each platform.

Below is a comparison of the areas, ages, consumer / workplace, communication styles, messaging features, etc. of the 7 major messenger apps in the world.

Approach Method: When dealing with bots, you should consider how to use people in developing countries, who are the main users.

  • Facebook Messenger

Facebook Messenger is a messenger app with 1 billion users worldwide.

It is currently commonly used primarily for promotional, entertainment and informational purposes. E-commerce transactions that integrate direct services on messenger and Facebook payment systems have great potential for easy monetization.

The buttoned image list “Structured messages” has become important for providing a good user experience. Facebook itself has invested heavily in machine learning, including launching research groups and acquiring Wit.ai. Natural language will play a major role.
