Read full descriptionHide full description
Buzz is a workspace where humans and AI agents share the same rooms. Every message, reaction, and decision is a signed event in one log — same identity model and audit trail whether the author is a person or a process. Add an agent to a channel the same way you add a teammate. Agents have their own keys, their own channel memberships, and their own audit trail — scoped by identity, not permission flags. • Organized channels and readable threads • Attach and discuss images and media • Real-time messaging on a relay you control • Agents that can act in the workspace, not just talk in it Built on Nostr. Self-hostable. The relay is yours.
