Hypothesis Slack

Some members of the Hypothesis community communicate with each other using Slack, an online tool that enables us to talk about annotation technologies, practices, and events in public and private groups and message each other directly.

Sign Up

Sign up online to join and share this page with your colleagues who are also interested in or working with annotation.

Once you sign up, you’ll receive an email that lets you know how to access the Hypothesis Slack for the first time.


When you log in, you’ll automatically be a member of the #public channel, where we talk about annotation generally, and the #random channel, where conversation is — well — random. Click on the word CHANNELS to browse other public channels in the Hypothesis Slack to find more specific conversations.
