Is very interesting, kind of Discord over nostr. It supports clients for multiple platforms,, including a web version.

You can add multiple nostr relays that support NIP-29 group chats, public or private.
Then people can create group chats, private or public and manage them to discuss.

With a private relay (where only certain npubs can post, view) is a powerful tool,, even for companies.

This is unstoppable. This is the real power of nostr not bullshit public fights like on twatter and shitposting.

I suggest to give it a try:

• run your own private relay
• add it to nostrord
• create a bunch of groups
• invite friends and family and chat in private
• create some public group chats and let people test
• join to existing public chats (remember that are PUBLIC and anybody can read them, so be careful what you post)
