Chat bots as an additional channel for user acquisition?

Hello everyone,

I was thinking about using chat bots as simple interfaces to side-projects.
I don't mean future predicting, regular conversation supporting with full blown analysis solutions. But, rather simple chat interfaces to data and services provided by the projects.

The purpose of that solution would be to provide an additional way to interact with systems alongside mobile and web apps. Perhaps, it can be a way for potential users to learn about your projects.

Has anyone tried building one and using it for user acquisition purposes? Do existing messaging platforms actually give new bots any exposure for discoverability?

Thanks :)
