Make Zulip the communication hub for your class.

Zulip is the organized team chat app that is ideal for both live and asynchronous conversations. Post lecture notes and announcements, answer students’ questions, and coordinate with teaching staff all in one place.

Use topics to organize the discussion

Zulip has the best user experience of all the chat apps I’ve tried. With the discussion organized by topic within each channel, Zulip is the only app that makes hundreds of conversations manageable.

Powerful formatting

I used Piazza & Zulip. Piazza lets students ask questions anonymously. Zulip better all-around for chatting, announcements, group work (has built-in LaTeX, as well as threading). Zulip basically replaced email for my class. Easy to pick up if you've used Slack & email before.

Interactive messaging

Participants across six continents signed up for my graduate-level classes when I decided to open them up to the world during the pandemic. Zulip became a central hub for asynchronous Q&A and posting Zoom links for lectures, whiteboard PDFs, and announcements. Zulip’s topics, and the ability to change the topic of someone else's message, has made it much easier for me to keep things coherent. It’s super easy to discuss technical material using the TeX integration, and spoilers are a great way to answer questions about homework without depriving students of a chance to keep thinking about the problem on their own.
