1. All the features support the APK and IPA or not?

ConverseKit for the web does not have APK or IPA. It is a plugin that is installed on your site. Are you referring to the Conversation app? The Conversation app allows you to build APK and IPA files, yes.

2. When will you get a Video chat into it?

We do not have an ETA on this yet.

sorry that I don't make you understand clearly about my question.

All the features of ConverseKit for Web will support my site or not? If I installed it into my website and then I convert my website into API and IPA. ConverseKit for Web still works the same or not with my APP?

The Conversation app allows you to build APK and IPA files (I don't talk about this one)

I have no idea what do you mean by converting your website to API and IPA. As long as it is rendered on the web, it would work on the web.
