Is Google Drive a chat app? Is Google Photos a drive app? I don’t know what you mean

Once you open a file, it is very much a chat app. Comments and chat work for anything you can preview btw, not just Google Docs stuff.

Not sure how you can access the chat in the directory view.

In Google Photos shared albums there is a tab that I can only describe as a chatroom.

Isn’t there a difference between having a tab that is similar to a chat, to being a chat app?
