I would like one like this.. (Slack/Discord alternative) with a native iOS app, realtime push notifications, and self-hosted backend such that my AI assistant can be a “user” on it and participate in conversations like a team member(who has a lot of knowledge at their finger tips).

I can’t find any such free thing that has a native iOS app.

Buzz was one I looked at but it was way too complicated with Nostr and a bunch of things that are way too much for what I intend to use it for… :-(

This - Strafe, Chatto, Stoat all fall apart in the native iOS app requirement..
