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.

Let's Decide helps a group make a decision together, without the endless back and forth. Instead of a plain yes/no poll, everyone can say how much they want each option. Let's Decide then shows what the group actually prefers, so the loudest voice does not win by default. WHY PEOPLE LIKE IT • No login required. Create a poll, share a link or code, and anyone can vote in seconds • See the group's real preference, not just a raw count of first choices • Works for lunch, trips, movie nights, team decisions, and anything else a group needs to settle FOUR WAYS TO VOTE • Slider: say how much you want each option, from 0 to 100 percent • Ranking: drag the options into your preferred order • Star rating: give each option a star score • Quadratic: spend a budget of points across the options GROUPS AND RECURRING DECISIONS Create a free account to keep your groups and their polls in one place. Same question every week? Re-poll it with one tap instead of typing it again. Get a notification when a new poll is waiting for you (opt-in) PRIVATE BY DESIGN • Use the app without an account • Anonymous voting stores only a display name you pick • GDPR-ready: access or delete your data at any time • Delete your account and personal information from inside the app whenever you want Stop guessing what the Group wants.
