At the moment we offer integration with Slack and JIRA.
You can link a document to a new Slack channel (private or public) and our Slackbot will then send notifications to that channel when new questions, arguments, and comments are added, a decision is made or poked.
We also offer an integration with JIRA where you can create new JIRA issues directly in Delibr. A link is also created on the issue in JIRA such that you never need to look for the specification.
Next up is probably Trell.
Please comment below if there are any other integrations that you would like us to look into.
