Google as a whole (especially in America) has a slew of services entirely comparable to WeChat. The problem is not many people use them.

They have phone and internet plans, they have mobile and desktop OSs, they have self-driving taxis, they have email, they have IM, they (had) a social network, they have a payment system, they have cloud storage and computing, they even have actual phones and computers. Sure, they miss a couple of things like a marketplace, but if US citizens somehow were forced to use all-Google devices they would definitely do everything with Google Search, Google Duo, GMail and Google Pay just like the Chinese do everything via WeChat. In that case obviously Google would integrate all their services even tighter by allowing almost everything to be done through their IM or email, but right now they are much more similar to WeChat than you might think
