I was about to say the same thing - I use Zulip at current employment - and after you get used to it it’s pretty great software that already solves all the problems struct aims to (without the AI nonsense)
Founder of Struct here. I looked at Zulip before starting Struct. And I'm sorry -- I don't think it's the same. Threads in Zulip are really sub-channels, and the idea of a unified feed like "All Threads" doesn't exist -- at least, that was my perception of Zulip. And just looking at the site right now, it feels the same as before. I could be wrong.
Struct is different. It's a reimagination of what a chat platform would look like if you were to completely give up the idea of chats in a serial log of channels (IRC, Slack, Discord), and embrace threads and feeds whole-heartedly. When everything is a thread, the platform can work remarkably well for users.
> the idea of a unified feed like "All Threads" doesn't exist
I believe it does. You get a feed of all messages; and still organized by a topic, quite conveniently.
I don’t use it, though, since from anywhere in GUI I can immediately jump to the next unread message, irregardless of topic or stream, simply by pressing “n” on keyboard (preceded by Esc if I happened to be typing; my draft is saved reliably).
I don't understand why I'd need or want this. I saw it in the video and was horrified. Multiple feeds updating as I'm watching them is just too much going on.
When I'm chatting, I don't want to pay attention to 10 different things at once. I'm most productive when I am working on one task (with a single topic), which may require me to refer back to Slack periodically.
Struct looks like it has two differentiating features: 1) it surfaces irrelevant distractions in the All Threads channel, and 2) it creates the tl;dr summary. The former seems actively harmful to productivity, and the latter seems like it could be useful.
You could create a focused custom feed. For example, I have one for "tasks assigned to me". That's what I set to when I'm focused working.
That's the beauty right -- you can control and filter what you see. As opposed to channel based interactions, where your boundaries are set in stone on channel creation.
