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.
Smart Comms Hub

Every mailbox, calendar and workspace you own, in one calm, read-first place — Smart Comms Hub brings Gmail, Google Calendar, Google Tasks, Slack and Monday together, so you check one app instead of five. Start your day with an AI daily brief: emails awaiting reply, today's meetings, open tasks and unread threads, summarized before you've had coffee. Your inbox is triaged automatically. Messages that actually need a reply rise to the top, scored across every connected Gmail account, so nothing important gets buried under noise. See every Google Calendar merged into one view, with Google Tasks synced both ways. Slack DMs and mentions, plus Monday board updates, show up alongside your email so you stop switching apps to stay on top of work. When you want help replying, AI can suggest a response for email or Slack. Approved replies become Gmail drafts — nothing is ever sent or posted on its own. You're always the one who hits send. Stay in the loop with instant alerts and per-category controls, delivered even when the app is closed. Choose from five ambient themes with deep dark versions, unlock with Face ID, and keep your settings synced across every device. Privacy is built in from the start. You can delete your account and all its data from Settings whenever you want, no questions asked. Download Smart Comms Hub and turn your scattered inboxes into one calm, unified view of your day.
