Online chat 1x1 between users by type VK, is there a similar one for WP?

Question

Chats

You need a chat like VK, you can do without groups, emoticons, etc., you need just a similar design, that is, a pop-up window with contacts + a separate page with contacts, an alert (if there is also a sound, then super) and always in live, without reboots etc.
Both paid and free are interested. I searched, everywhere they rivet only for business for communication, 1x1 it is difficult to find something pleasing to the eye. Can anyone advise based on their experience?
Immediately ask without wp recall.
