Aside from being able to import documents from various services, Quip can stream updates from 1,000's of services directly into a Chat Room or document thread.
Integrations enable you to connect hundreds of other products, including Dropbox, Zendesk, JIRA and more, directly to Quip. When you add an Integration, you can receive messages about activity on these other services. You can attach these messages to a group chat or a document, and your whole team can share, interact, and discuss the messages together. With Integrations, everything you add becomes something you can collaborate on!
