Looks like an interesting idea! I've been thinking about doing something similiar.

Couple ideas:

- I see a lot of references to "zulip server" in the README. I have no idea what it is and whether I even need it? What I'm really interested in is what the app does, how to run it and how it looks like

- Consider swapping the top link to the one pointing to glitch. Much better to see it working rather than pointing to a signup form

- Perhaps add a screenshot of the app in the README.md?

- Maybe also provide a docker-compose file, so users can quickly try it out?

Good stuff!
