Hipchat: Hipchat とは
What is HipChat?
HipChat is our on-premise instant messaging tool. HipChat enables your team to work better together by making it easy to share ideas, updates, code and files in real-time, anywhere.
HipChat can integrate with a lot of other tools, but it perfectly integrates with Atlassian tools such as Confluence or Jira. Thanks to integrations, you and your teams can communicate and receive notifications from those tools in HipChat rooms.
