Quip has great integration, it's a great platform for project management and customer service is great.
Quip is a great tool to use for your team when quickly brainstorming and jotting down ideas. It strips itself of unnecessary formatting/UI options and provides you a clean slate to work smarter.
Beautiful UI design and user friendly. Import export functionalities are really good.
The only small complaint I have is that the text formatting controls are a bit limited. The other problem is how Quip doesn't work well with PDF's.
There is often latency issues that we run and some of the syncs are not done properly. It has some problem with commenting.
Some of the features can be hard to locate when switching over from other comparable platforms. Other than that there isn't too much to complain about.
