Google Allo is set to have a big change on the web version of the chat app that should make it far more useful going forward. In a Tweet last week, Google Principle Engineer for Google Allo, Justin Uberti said that device independence for the web version is on its way.
Yes, we are in the process of migrating the backend system to support completely independent devices.

What this would mean is that you could use Allo on your laptop without having to have it connected to Allo on your phone.
