Zulip has been a game changer for our group’s collaboration. It combines the immediacy of chat with the structure of email, allowing complex projects and parallel discussions to stay organized without chaos. We no longer lose context between meetings; every idea, file, and decision is easy to find and build on.

For more than a year, Zulip has been the cornerstone of our online Category Theory community. We greatly appreciate the seamless integration of Latex in every message as well as being able to get sidetracked (which, let’s face it, happens a lot with mathematicians) without compromising an entire conversation: we can simply create a new topic for every tangent! Moreover, the flexible channels-and-topics system greatly helps us navigate through the constant influx of messages, as it is simple to tell if a message is relevant to one’s interests.

All in all, Zulip enabled us to create an unprecedentedly extensive, active and vibrant community for all category theory enthusiasts out there.

As a research consortium spread across 14 locations in Germany, we use Zulip to communicate with each other in a low-threshold manner, without the overhead of email. Even with more than 200 users across different institutions, Zulip’s model of topic-labeled conversations makes it easy for our team members to keep up-to-date on what’s relevant, and work productively together.
